[solved] recursive bulkrenaming

Hi, I have been using a renaming script from brisbin33, he was posting in "Handy self made command line utilities".
#!/bin/bash
# pbrisbin 2009
# take a retardedly named file or directory and rename it
# sanely
# adjust translate() as needed
message() { echo 'usage: renamer (--fake) <target> ...'; exit 1; }
# could always use more shit here...
translate() {
tr -d '\n' | tr -d '\t' | tr -d \' | tr -d \" |\
sed -r -e 's/.*/\L&/g' \
-e 's/[ -]/_/g' \
-e 's/_+/_/g' \
-e 's/^_|_$//g' \
-e 's/ä/ae/g' \
-e 's/ö/oe/g' \
-e 's/ü/ue/g' \
-e 's/ß/ss/g'
rfile() {
local dir old new
dir="$(dirname "$1")"
old="$(basename "$1")"
new="$(echo $old | translate)"
if [[ "$old" != "$new" ]]; then
if $fake; then
echo "$dir/$old --> $dir/$new"
else
mv -iv "$dir/$old" "$dir/$new"
fi
fi
rdir() {
local dir
while IFS='' read -d '' -r dir; do
rfile "$dir"
done < <(find "$1" -depth -print0)
[[ -z "$*" ]] && message
# allow a pretend run
if [[ "$1" = '--fake' ]]; then
fake=true
shift
else
fake=false
fi
# do it to it
for arg in "$@"; do
if [[ -d "$arg" ]]; then
rdir "$arg"
elif [[ -e "$arg" ]]; then
rfile "$arg"
else
message
fi
done
It saved me years of lifetime...but I still have one problem with it. When there is a name collision (a file with that name already exists and the script can't proceed therefore) the script just stops. I would prefer it, if the script could rename the file anyways, but append a number to get a unique filename (img.jpg => img02.jpg). Then I could do the cleanup later.
Sadly my scriptingskills are almost nonexistent. I am not even sure, if I have to implement that logic in the rfile-/rdir-functions or in the "do it" part of the script. As I have absolutely no clue, a little help would be much appreciated.
Thanks.

This seems to work.
Sorry, I should have posted the whole function before ;-)
// Edit: I only tested it with one file at first; Now i noticed my mistake
rfile() {
local dir old new
dir="$(dirname "$1")"
old="$(basename "$1")"
new="$(echo $old | translate)"
if [[ "$old" != "$new" ]]; then
if [[ -e "$new" ]]; then
local i=1
while [[ -e "${new}_$i" ]]; do
let i++
done
new="${new}_$i"
fi
if $fake; then
echo "$dir/$old --> $dir/$new"
else
mv -iv "$dir/$old" "$dir/$new"
fi
fi
This time it should be correct ...
Sorry again.

Need help solving recursion in workflow

Here is the workflow, which kicks off automatically when a list item is changed. ULS logs report recursion occurring. I don't see where. I assume because oldmodifiedtime field is being updated, but I would think the Stop workflow action would prevent
looping.
Step 1
If Current Item:Case Status equals Closed
Stop the workflow and log Workflow stopped because case status is closed
Else if Current Item:OldModifiedTime is less than Current Item:Modified
and Current Item:Modified By equals Current Item:Requester
and Current Item:EMailed Assigned equals Yes
Email AAC IT Distribution
then Set OldModifiedTime to Current Item:Modified
then Stop the workflow and log Requester updated case
Else if Current Item:OldModifiedTime is less than Current Item:Modified
and Current Item:Assigned To contains Current Item:Modified By
and Current Item:EMailed Assigned equals Yes
Email Current Item:Reguester
then Set OldModifiedTime to Current Item:Modified
then Stop the workflow and log IT updated case
(Note: the last line Stop workflow goes with last Else clause, it just pasted here spaced down and I can't seem to get rid of the extra line spacing.)
Can anyone help with a resolution?
Thanks,
Joan

Two errors:
AutoStart Workflow: Microsoft.SharePoint.SPException: Recursive workflows are not permitted. at Microsoft.SharePoint.Workflow.SPWorkflowAutostartEventReceiver.<>c__DisplayClass1.<AutoStartWorkflow>b__0(SPSite superUserSite,

WinWF Internal Error, terminating workflow Id# 8c200992-8b03-4533-8cc1-e66f4472794a
The Id# matches with the history list. Also spot checked other times, different list items. Same errors, matching with history list.
No errors in UI. No one who updates an item (user or IT) reports error. When I tried to run Cancellation & Error report in UI, I get Error, report contains no data. Return to site.

[SOLVED]Recursively use makepkg with python...or bash!

I am basically trying to build a base Archlinux system from scratch on my eee pc. I researched Pacbuild a little bit but decided to try my own had at this.
After being completely unsuccessful at trying to write bash scripts with loops and variables and whatnot, I took a look at python. I basically just searched a bunch of python tutorials on google and came up with this. So..this being my first script and all I was wondering if this would be the right way to do this. It basically works except with no error checking and if I want it to stop i have to press ctrl-c until the loop ends...but other that it works fine.
#! /usr/bin/env python
#import bash commands
import os
import sys
#open pkglist file
pkglist = open('/home/rhune/list', 'r')
pkgname = pkglist.readline() #read pkgname in file
while len(pkgname) != 0:
pkgname = pkgname.rstrip('\n') #delete newline
os.chdir('/home/rhune/eeepkgs')
os.chdir(pkgname) #cd /home/rhune/pkgname
os.system('makepkg') #run makepkg in working dir
os.chdir('/home/rhune/eeepkgs') #cd ../
pkgname = pkglist.readline() #read pkgname in file
pkglist.close() #close file
The "list" file is a list of folders in the directory im pointing to.
I also plan on having it accept an argument of what folder to run in and using the tempfile to create the directory list, and with some sort of error checking. But thats a whole nother project.
Any comments or contributions appreciated!
edit: is there a way to check if makepkg successfully compiles the package? i.e. does it return a 1 or 0 or some sort of value? Or would i have to parse the actual output of it?
Last edited by rhune (2009-08-28 04:48:05)

Thanks much! This works, just gotta pick a better place to store the output.
#!/bin/bash
cd $1
for folder in $(find * -type d)
do
cd $folder
makepkg -s
if [ $? -gt 0 ]; then
echo $folder >> '/home/rhune/failed'
else
echo $folder >> '/home/rhune/passed'
fi
cd ../
done
Also figured out this in python:
!/usr/bin/env python
import os
import subprocess
base = "/home/rhune/test/pkgs"
failed=[]
dir = os.listdir(base)
dir.sort()
os.chdir(base)
print dir
for x in range(len(dir)):
os.chdir(dir[x])
retcode = subprocess.call(['makepkg', '-s'])
if retcode==1:
failed.append(dir[x])
os.chdir(base)
print failed
The bash one seems a bit simpler though.
Also, this:
#! /usr/bin/env python
import os
import sys
deplist=[]
depname=""
count=0 #count apostrophes
#search for depends= line in pkgbuild
with open('/home/rhune/pkgs/yaourt/PKGBUILD', 'r') as pkg:
for deps in pkg:
if "depends" in deps: break
deps=deps.strip('depends=')
#insert depnames into deplist
for x in deps:
if x=="'": count+=1 #counts apostrophes
if x.isalpha(): depname+=x
if count==2:
deplist.append(depname)
depname="" #reset depname
count=0 #reset count
#pbget for each dependency in list
for x in range(len(deplist)):
os.system('pbget --arch=i686 '+deplist[x])
Reads a PKGBUILD file and pbgets dependencies. Need to change sys to subprocess, didnt realize it was outdated. Still needs a little work, but its practically done. Also made a sed script to go through each directory and change the PKGBUILD to use gcc-4.5 for the atom optimization.
#!/bin/bash
cd $1
ls -l
for folder in $(find * -type d)
do
cd $folder
sed -s 's/\.\/configure/CC=gcc-4.5 \.\/configure/' PKGBUILD > tmpfile ; mv tmpfile PKGBUILD
cd ../
done
These being the first time ever writing any sort of scripts, i think im getting the hang of it. Thanks to a little (and i mean little) bit of c++ knowledge.
So im basically ready to compile the whole system, hopefully itll all work!
Thanks
edit: also, maybe a stupid question, but why does $0 -gt 0 work? does the script return a 1 or 0 after each iteration or is it from makepkg?

[SOLVED] Delete recursively all files with certain extensions

Hi all,
I am trying to recursively delete files with specific extensions. Many of these files have names containing spaces. The following, that I found googling around, didn't work:
find /media/TSUNAMI -name '*out' -or -name '*aux' -or -name '*log' -or -name '*.blg' -or -name '*.toc' -or -name '*.bcf' -or -name '*.swp' -or -name '*blx' | rm
find /media/TSUNAMI -name '*out' -or -name '*aux' -or -name '*log' -or -name '*.blg' -or -name '*.toc' -or -name '*.bcf' -or -name '*.swp' -or -name '*blx' -type f -ok rm '{}' ';'
find /media/TSUNAMI -name '*out' -or -name '*aux' -or -name '*log' -or -name '*.blg' -or -name '*.toc' -or -name '*.bcf' -or -name '*.swp' -or -name '*blx' -exec rm -f '{}' \;
find /media/TSUNAMI -name '*out' -or -name '*aux' -or -name '*log' -or -name '*.blg' -or -name '*.toc' -or -name '*.bcf' -or -name '*.swp' -or -name '*blx'| xargs /bin/rm -f
find /media/TSUNAMI -name '*out' -or -name '*aux' -or -name '*log' -or -name '*.blg' -or -name '*.toc' -or -name '*.bcf' -or -name '*.swp' -or -name '*blx' -exec /bin/rm -f '{}' \;
find /media/TSUNAMI -name '*out' -or -name '*aux' -or -name '*log' -or -name '*.blg' -or -name '*.toc' -or -name '*.bcf' -or -name '*.swp' -or -name '*blx'| xargs -0 rm
and I think that it was the following that deleted all the files (except the directories):
find /media/TSUNAMI -name '*out' -or -name '*aux' -or -name '*log' -or -name '*.blg' -or -name '*.toc' -or -name '*.bcf' -or -name '*.swp' -or -name '*blx' -type f -delete
What am I doing wrong here?
Thanks a lot in advance.
PS. While writing this I realized that I fogot the dot in out, aux, log, and blx
PS2. I'm experimenting around and don't mind deleting all the files if I do a mistake

The implicit "and" operator binds stronger than the "or" (-o) operator. Therefore
| -name a -o -name b -delete |
will be grouped like this:
| (-name a) -o ( -name b -delete ) | .
You want to group it like this:
| ((-name a ) -o ( -name b )) ( -delete ) | ,
so you need to add some manual grouping:
| ( -name a -o -name b ) -delete |

Firefox 3.6 when I open a SWF file, a wrong mouse click, it show a recursive open window until the PC resource is used up or the system hang up, I try to reinstall firefox but not solved.

Windows XP SP3, flash player 10.2, Shockwave 11.5.9.240 , when I open a SWF file with firefox 3.6.15, it shows some options to choose action and I made a wrong click. The firefox nightmare is a "open recursive windows" until the system hang. When I use Internet Explorer 8 to open it, it is fine, Try to uninstall firefox and reinstall it, but in vain, how can I restore it?

You don't have the Shockwave Flash Player installed for Firefox. You may have the ActiveX version installed for IE, but Firefox needs the Plugin version. And Shockwave 11.5.9.240 that is installed for Firefox isn't the same thing.
1.Download the Flash setup file from here: 
[http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player.exe Adobe Flash - Plugin version]. 
''Or maybe get the previous '''r102''' version from here. IMO, there's problems with the latest version of Flash.'' 
http://kb2.adobe.com/cps/142/tn_14266.html 
Save it to your Desktop. 
2. Close Firefox using File > Exit 
then check the Task Manager > Processes tab to make sure '''firefox.exe''' is closed, 
{XP: Ctrl+Alt+Del, Vista: Shift+Ctrl+ESC = Processes tab}
3. Then run the Flash setup file from your Desktop.
* On Vista and Windows 7 you may need to run the plugin installer as Administrator by starting the installer via the right-click context menu if you do not get an UAC prompt to ask for permission to continue (i.e nothing seems to happen).

[solved] PCRE recursive replacing

Hi all,
I have tried to understand PCRE but am ATM busy untying the knot in my brain. Maybe someone of you is so proficient the he/she can point to a solution easily.
I want to use PHP's preg_replace to replace some bbcode with valid html, but want to handle nested bbcodes.
Example:
This is [ i ]some text in [ i ]italics[ /i ] that has [ i ]italics even [ i ]inside[ /i ] of itself[ /i ][ /i ] so it can be a mess.
(with spaces so it doesn't get formatted by the forum software here.)
What I want my html do is switch between '' and ''. I suppose with those spans I can use nesting in turn, so I don't need to before switching, provided that I deliver the closing where the closing bbtag is. But with all those recursions and lookaheads, let alone replacing, the resources I could find got me lost.
Up to now (before me messing with it), the actual code looks like this:
$pattern = array(
"/\[i\](.*?)\[\/i\]/si",
$change = array(
"$1",
$string = preg_replace($pattern, $change, $string);
Any ideas? TIA,
Andreas

im pretty sure that regex pattern can be improved, but i don't know enough to help;
but you did mention that it's slow, so i thought maybe regex wasn't necessary since you're only matching and
<?php
$str= 'This is [i]some text in [i]italics[/i] that has [i]italics even [i]inside[/i] of itself[/i][/i] so it can be a mess.';
function clock($t)
return sprintf('%f', round(microtime(TRUE) - $t, 6));
echo "$str \n\n";
class MYCLASS
var $currentlyItalics;
function bbToHtmlItalics($input)
$regex = '#\[i]((?:[^[]|\[(?!/?i])|(?R))+)\[/i]#';
if (is_array($input)) {
if($this->currentlyItalics) {
$input = ''.$input[1].'';
} else {
$input = ''.$input[1].'';
if(preg_match($regex, $input)) $this->currentlyItalics = !($this->currentlyItalics);
return preg_replace_callback($regex, array(&$this, 'bbToHtmlItalics'), $input);
function altbb($str)
$alt = FALSE;
$out = '';
$tks = explode('[i]', $str);
$end = array_pop($tks);
foreach ($tks as $tok) {
if ($alt) {
$sub = 'italic';
} else {
$sub = 'normal';
$out .= "$tok";
$alt = !$alt;
return str_ireplace('[/i]', '', $out.$end);
$bb = new MYCLASS();
$t = microtime(TRUE);
echo $bb->bbToHtmlItalics($str).clock($t);
echo " ";
$t = microtime(TRUE);
echo altbb($str).clock($t);;
?>
i just posted everything i used,
as you will see, the string method is a lot faster than the regex one and i think a lot simpler also
i haven't done much testing or anything, just implemented a thought. hope it helps

This sounds like a problem that is specific to the package or the code itself. I'm don't use either of those, but I can give you some general recommendations.
`pacman -Syu` has been known to fix compilation errors when a package depends on a header file that is owned by another package. Unfortunately this works the other way around, too: the packages you're trying to install might depend on an older header file that has been upgraded by pacman. The latter is usually a result of outdated code and is much harder to fix.
`grep png_error_ptr_NULL -R /usr/include` will show you which header files the identifier appears in (if any). One of them should contain the declaration, so make sure that file is #include'd in i_sshot.c
For best results, I recommend contacting the package maintainer, posting a comment on the AUR package page, or contacting upstream directly. Those users are likely to be more knowledgeable about this software than the rest of us on the forum.

(solved)How to use jpegoptim recursively in subfolders.

Hello ,
I want to optimize some images without changing names with many subfolders loaded.
I am not good at shell script. I found this for jpegtran but package does not work.
How can I modifiye it for jpegoptim?
#! /bin/sh
# Usage 1:
# optimize-images.sh /images/dir
# Usage 2:
# cd /images/dir
# optimize-images.sh
EXTENSIONS="jpe?g"
if [ -z "$1" ]; then
DIR="`pwd`"
else
DIR="$1"
fi
# Optimize JPEG images
find "$DIR" -regextype posix-egrep -regex ".*\.($EXTENSIONS)\$" -type f | xargs -I{} jpegtran -optimize -progressive -outfile "{}.optimized" "{}"
# Rename xxx.jpg.optimized -> xxx.jpg
find "$DIR" -name '*.optimized' -print0 | while read -d $'\0' file; do
chown $(stat -c "%U:%G" "${file%.optimized}") "$file"
chmod $(stat -c "%a" "${file%.optimized}") "$file"
mv -f "$file" "${file%.optimized}";
done
ps1: also found this while google in but I dont know where to write it :
optimize() {
jpegoptim *.jpg --strip-all
for i in *
do
if test -d $i
then
cd $i
echo $i
optimize
cd ..
fi
done
echo
optimize

works with jpegoptim. I think the same will occur with jpegtran. I had a $PATH value for ruby , it was ruining my bashrc. I commented it and works now.
How exactly were you trying to use the script for jpegtran? Did you put it in your ~/.bashrc? You don't have to put your script location in your $PATH to run it, you just need to use the full path then.

[Solved] Kde unstable: Folderview recursive mouseover gone?

In folderview you used to be able to mouseover a folder and browse it's contents (handy, no need to open a file manager)but now it just tells me how many items are in it. Is there an option somewhere I need to tag? Can't believe such a useful feature would have been removed...
Cheers!

It looks like in KDE 4.4 there is no option to disable it. (see http://chakra-project.org/bbs/viewtopic.php?id=1310)Maybe for 4.5 they added the option, but disabled by default. Have you checked the folderview settings? (sorry, I feel stupid asking that question)

[SOLVED] bash recursive function

#!/bin/bash
IFS=$'\n'
function low {
if [ -d "$1" ];
then
DIR="$1"
cd "$DIR"
fi
pwd
for f in `find . -maxdepth 1`; do
[ -d "$f" -a "$f" != "." ] && low "$f"
file=$(echo $f | tr A-Z a-z | tr ' ' '_')
[ -e "$f" ] && [ ! -e "$file" ] && mv "$f" "$file"
done
[ "$DIR" ] && cd - > /dev/null
low .
unset IFS
this should walk through all subdirectories and rename the files inside there
however, it only goes through the first directories it finds.
i.e. i have:
/tmp/test1/
/tmp/test1/sub1/
/tmp/test2/
/tmp/test2/sub2/
and the script does:
[rob:/tmp/] ./lowandspace
/tmp/
/tmp/test2
/tmp/test2/test2_2
what am i missing?
or is bash screwing up?
Last edited by robmaloy (2009-05-20 09:46:54)

why would you test -f $file after a find?
this should work, i use something very similar except mine renames directories too so it's a bit easier to manage. i overused the double quotes b/c i can't test right now and i want to be sure it handles spaces appropriately
find ./ -type f | while read file do
dir="$(dirname "$file")"
old="$(basename "$file")"
new="$(echo "$old" | tr A-Z a-z | tr ' ' '_')"
if [ "$new" != "$old" ]; then
mv "$dir"/"$old" "$dir"/"$new"
echo "$old was renamed to $new"
fi
done

I have installed XE Oracle Database Version 9.0.1.4.0 in VISTA Home Premium and Oracle Developer suite10g version 9.0.4.0.19
I received the following error message when I try to connect the Database in Form Developer or sqlplusl.
ORA-00604: error occured at recursive SQL Level 1
ORA-01009: missing mandatory parameter
but when i run through XE-database it works fine..
Any one can you help to solve this problem.
Thanks in Advance.

I guess you meant to ask on the XE forum, as this has nothing to do with ADF or JDeveloper.

THE ONE WHO SOLVES THIS PROBLEM IS GREAT!

I'm serious. I am so fed up I am with this problem. Ground rules: you must NOT just give me code. I need to be able to know why my problem is happening, and how to fix it myself. I'm a grad student and am bound by a code of conduct. I don't have any more time to spend investigating this. It could be something simple or complex...I am at a loss.
Here is the situation: I'm developing this console java application on my Windows PC. When I run it on my pc, it runs in under a minute. However, when I transfer my program to the servers at my school (sun unix workstations) it takes a ridiculous amount of time to run the same program. I am told that 80% of the students in my class have their programs running in less than 5 minutes. Almost all of them didn't have to do any kind of optimizations. They just wrote it, and it worked. My program is averaging 10-15 min, but my prof runs it locally at school, and says it takes 40 min!
The entire program is posted below. Please forgive me for not commenting so great. They were better at first, but when I started moving things around and changing everything, I threw comments out the window. Still, the existing comments should be helpful in understanding what I'm doing. NOTE: Below the code is the DTD that all the .xml files I'm parsing conforms to. Here are a few links to .xml files that represent part of the dataset. The actual dataset consists of 40 files totaling 30MB.
http://www.geocities.com/c_t_r_11/items-1.xml
http://www.geocities.com/c_t_r_11/items-10.xml
http://www.geocities.com/c_t_r_11/items-20.xml
the dtd is at:
http://www.geocities.com/c_t_r_11/itemsdtd.txt
And here is the code:
/* Instructions:
This program processes all files passed on the command line (to parse
an entire diectory, type "java MyParser myFiles/*.xml" at the shell).
At the point noted below, an individual XML file has been parsed into a
DOM Document node. You should fill in code to process the node. Java's
interface for the Document Object Model (DOM) is in package
org.w3c.dom. The documentation is available online at
http://java.sun.com/j2se/1.4/docs/api/index.html
A tutorial of DOM can be found at:
http://java.sun.com/webservices/docs/ea2/tutorial/doc/JAXPDOM.html#67581
Some auxiliary methods have been written for you. You may find them
useful.

REMEMBER: Please do not just post the correct code. This will violate my code of conduct. I need tutoring--consultation.

If I was trying to get someone else to do my work,
I wouldn't be posting this saying what I have said
would I? I'm not unwilling to do the work myself.From what was stated in your OP, it seemed that you
were.I'm sorry if it seemed that way. I don't want something for nothing. I've spent MANY hours, which I don't have, trying to work this out. I have hit a point where I don't think my expertise is going to solve the problem. That's why I've turned to some experts who might say something along the lines of, "Hey, I know what that is...you're compiling against... and on the Unix box, it's compiling against..." I was NOT looking for something like, "See the code below that fixes your problem."
The only problem is that I don't have direct access
to the sun unix machines I'm running the app on,
so I can't run a profiler on it. Ah, okay. So the only knowledge you have of how it
performs on those machines is from your instructor
running it and then telling you how long it took?No. I can SSH into the servers and run the program from a command line. But I wouldn't be able to install any profiler programs.
You could ask your prof to run it with -Xprof or
-Xhprof or whatever. Or you could put in a bunch of
timing statements to get a rough idea of which parts
are making it take that extra 39 minute or whatever.is -Xprof a java command line option? If so, I will look into doing that. Maybe it's available on the machines at school. Thanks for that input.
