Simple bash-batch-compiler improvements

hey there,
i made a simple bash script for compiling many *.cpp files in one dir.
#! /bin/bash
find . -name "*.cpp" -exec g++ {} -o {}.sh \;
but if an *.sh already exists it shouldn't compile, also it would be nice to have it named program.sh not program.cpp.sh my bash skills are rather limited, think one could help me out folks
cheers,
detto

Mh, got another one here :< Still didn't find a GOOD sed tutorial with regexp. It's so damn complicated in my eyes.
Well, I figured something out, but it has a error inside
for f in *.jpg ; do mv "$f" `echo "$f" | sed 's! 1280!!'` ; done
When executing it prompts for every *jpg file with "mv: specified target »(10).jpg« is no directory". :?

Watchless - a simple Bash helper for LESS to CSS compilation

Here is a simple Bash tool for LESS files compilation, watching your .less files using inotifywait and compiling CSS on file change.
Supports @import-ed files. Compiled files can go in the current directory or in another directory, keeping the directory structure intact (~/Project/less/style.less to ~/Project/css/style.css for example)
Not well tested, may be dangerous.
AUR: https://aur.archlinux.org/packages/watchless/

I place all my LESS files, along with all of the JavaScript files in a sub-directory called _src (for source files). The _scr folder is Cloaked so that it is not included in file transfers. The structure looks like
_src
    js
          bootstrap
              ..... // files go here
          fonts
              ..... // files go here
          jquery
              ..... // files go here
          myscripts.js // scripts of my own that I want added
          scripts.js // contains imported JS files that are combined and minified into one production script
    less
          bootstrap
              ..... // files go here
          fonts
              ..... // files go here
          footer.less //
          form.less //
          header.less // these files are for the various parts of the template and or documents
          main.less //
          nav.less //
          styles.less // contains imported LESS files that are combined and minified into one production style sheet
I will then use PrePros to compile the JS and CSS files making for just two HTTP requests.
Have a look at source code (lines 7 and 110) of this site.
Incidentally, by using PrePros, not only do the LESS and JS files get compiled automatically, any saved changes are immediately visible in my browser without having to refresh each time.

Shell script for batch compilation of forms 10g on AIX 5.3L AS

Can anybody provide me the Shell script for batch compilation of forms 10g and reports 10g on AIX 5.3L AS?

Simple bash scripting help needed..

I want to learn som simple bash scripting in order to automate various tasks.. Im totally noob, so bear with me
First of all I would like to set configs without using nano.. is there a simple command for this? For example if i want change my hostname in /etc/rc.conf.. how can i print the current vallue and how can i change it`?
i was thinking something like this to get the current value:
# cat /etc/rc.conf | grep HOSTNAME=
which returns HOSTNAME="myhostname"
how can i change this value with one or more commands whitout touching the rest of the file?

A slightly naive solution:
CHOICE="lisa"
NAMES="homer marge lisa bart maggie"
if [ "`echo \" $NAMES \" | grep \" $CHOICE \"`" ]; then
echo "this is how you do it"
fi
The extra spaces inside the escaped quotes are to ensure that only a whole word is "matched".
You can also replace the elif's with a loop through a list of "the other variables". Then you'd use the loop variable instead of $CHOICE above.
grep can check on word-bounderies with \< and \>, or with the -w switch. The -q switch suppresses any messages and exits with exit-code 0 when the first match is found:
if echo "${NAMES}" | grep -qw "${CHOICE}"; then
Nice and readable, should work, but i haven't tested it
EDIT:
Procyon wrote:CHOICE="lisa"
NAMES="homer marge lisa bart maggie"
if [[ $NAMES =~ $CHOICE ]]; then echo match; fi
This one also matches elisa, ie. no check on word bounderies. You should be carefull with that

Forms 11g Batch Compilation Script

Hi,
I have seen few threads in this forum on the topic "Batch Compilation of Forms"
For instance batch file to convert fmb to fmx
But i could not find a way to do the batch compilation in Forms 11g?
How do I batch compile my Forms in 11g?
Thanks,
Ram

Nothing has changed from the old versions to version 11. Compilation is done the same way as it always has in the past. The only difference (depending on which version you start from) is the the name and location of the compiler executible. The new file name is frmcmp (.exe if you are using Windows and .sh for Unix). All old example scripts should work in the new version as long as you make this change.

Solaris 11 - run a simple BASH script on computer startup

I need to have a simple BASH script run on my Solaris 11 machine automatically whenever the computer (re)starts. It should be run with root permissions and after the computer has fully booted. What is the easiest way to do that?
Thank you
Dusan

Hi user9368043
Yes, that should be right, and be intended this way.
See /etc/rc3.d/README and the following part from smf(5):
Legacy Startup Scripts
Startup programs in the /etc/rc?.d directories are executed
as part of the corresponding run-level milestone:
/etc/rcS.d milestone/single-user:default
/etc/rc2.d milestone/multi-user:default
/etc/rc3.d milestone/multi-user-server:default
Your question concerning upgrading to Solaris 11.1:
In the Gnome menus, you should look for (and start)
System --> Administration --> Update Manager
Let it do its work. It will give you a new boot environment, containing Solaris 11.1. Possibly, you have to perform upgrading twice. With "beadm activate", see beadm(1M), you can go back to Solaris 11.0 whenever you want.
"Local" parts of your zfs root pool, like /usr/local, home directories, /root, and so on, should be in separated file systems, and be mounted outside the root pool before upgrading. They are availlable then from any boot environment, and will not be duplicated. See more in zfs(1M), zpool(1M).
I strongly recommend upgrading. Solaris 11.1 is great.

Simple BASH script to update subversion files

This is just a simple BASH script that will update all .svn files in a specified directory. If an update fails, it will attempt to update all the subdirectories in the failed one, so as much will be updated as possible. Theoretically, you should be able to supply this script with only your root directory ( / ), and all the .svn files on your computer will be updated.
#! /bin/bash
# Contributor: Dylon Edwards <[email protected]>
# ================================
# svnup: Updates subversion files.
# ================================
# If the user supplies no arguments
#+ then, update the current directory
#+ else, update each of those specified
[[ $# == 0 ]] \
&& dirs=($PWD) \
|| dirs=($@)
# Update the target directories
for target in ${dirs[@]}; do
# If the target file contains a .svn file
if [[ -d $target/.svn ]]; then
# Update the target
svn up $target || {
# If the update fails, update each of its subdirectories
for subdir in $( ls $target ); do
[[ -d $target/$subdir ]] &&
( svnup $target/$subdir )
done
# If the target file doesn't contain a .svn file
else
# Update each of its subdirectories
for subdir in $( ls $target ); do
[[ -d $target/$subdir ]] &&
( svnup $target/$subdir )
done;
fi

Simple bash menu

I wanted a simple bash menu where arrow keys could be used to select items. So here it is. It requires cuu and cud in the teminfo or it fails to look nice.

Feel free to modify and adapt for your own personal usage.

[[ $# -lt 1 ]] && exit 2 # no menu items, at least 1 required
[[ $# -gt $(( `tput lines` - 1 )) ]] && exit 3 # more items than rows
# set colors
cn="`echo -e '\r\e[0;1m'`" # normal
cr="`echo -e '\r\e[1;7m'`" # reverse
# keys
au="`echo -e '\e[A'`" # arrow up
ad="`echo -e '\e[B'`" # arrow down
ec="`echo -e '\e'`" # escape
nl="`echo -e '\n'`" # newline
tn="$#" # total number of items
{ # capture stdout to stderr

Nice code.
I manually added j, k, and o (~Return) into the key checking part. I could use j,k or up,down to choose, but I wonder if that possible you can re-code to make it can accept multiple keys set in $au,$ad, and $nl.
Thanks. In the case statement you can add multiple keys, like:
"$au"|k)
<snip>
"$ad"|j)

I didn't want this which is why it's not in the script. At the bottom of the script, change tput cud $(( tn - 1 )) to tput dl $tn ; tput cuu1 and it should delete the lines.
Bug: does not work with fish shell, set distro (./smenu ArchLinux Debian Ubuntu Gentoo); I wonder how it fares with other shells and terminals.

RH9 Batch Compile Failures

I have a batch file set up to batch compile numerous projects one after the other for RoboHelp 9. The output is CHM format. When doing the compile, usually at least one project fails to completely compile and the log file shows only this information:
Adobe (R) RoboHelp Project Command Line Compiler version 9.0.0.228
Copyright (C) 2006-2007, Adobe Systems Incorporated and its licensors. All rights reserved.
Project: C:\TechComm\SPIRIT\source\projects\directd\directd.xpj
Layout: ssl_directd_hdi.
Output: C:\TechComm\SPIRIT\output\help\directdhdi.chm.
Scanning project for compilation....
Scanning finished.
Warning: No baggage file description.
There are no files attached to the project. The baggage file contains some CHMs that were used for remote links, but they are not included in the project.
Additionally, if I recompile this project using the batch file, it will build fine. How can I stop these initial failures? It's not just this project, but others will randomly not generate and the log file shows the same information.

Thanks for your suggestions.
Matt, I have tried "Mass Compile" and it is nothing to do with the FPGA. It just opens all your VIs, resaves them, and relinks them to their subVIs. This helps with some cross-linking issues.
Bruce, the behavior you describe is what I would have expected initially. However, it seems like I do have to recompile all the subVIs. Right now I don't see anything changing on the FPGA side if I recompile my FPGA shell VI, but not my subVIs.
It makes some sense that compiling the FPGA shell VI would not automatically recompile all the subVIs - the full compile including all subVIs takes about three hours, as compared to less than an hour to recompile the shell VI alone. So there is a strong reason to want subVI compiles to be independent of the shell compile.
Thanks,
Dave

Batch compile for FPGA?

Dear all,
I have an FPGA VI with many subVIs in my project. I would like to compile the entire project at once, but I can't seem to find a way to do this. So right now I have to pull up 30+ subVIs individually and compile them at the rate of about one every 20 minutes, which is really inconvenient.
Is there any way to do a batch compile of my project?
Thanks,
Dave Kielpinski

Batch Compilation of Reports

Hi ,
I have followed the Note:191529.1 and developed a script for a batch compilation.
#UNIX COMPILE REPORTS
#compile_rep.sh
for i in `ls *.rdf`
do
echo Compiling Report $i ...
rwconverter.sh userid=scott/tiger@bs817 batch=yes source=$i
stype=rdffile dtype=repfile overwrite=yes
done
My Code:
for i in `/letters_reports/acesrdf_10/ *.rdf`
do
echo Compiling Report $i ...
rwconverter.sh userid=aces/aces@acesdev1 batch=yes source=$i
stype=rdffile dtype=repfile overwrite=yes
done
--- i am getting the below error for the script.
"compile_rep.sh: line 21: /letters_reports/acesrdf_10/: is a directory"
if i try to test the script for one single report i get the below error:
"compile_rep.sh: line 21: /letters_reports/acesrdf_10/LE-CMG002A.RDF: cannot execute binary file".
Please let me know the correct way.
Thanks,
Yugi

U could try this:
for i in `ls /letters_reports/acesrdf_10/ *.rdf`
do
echo Compiling Report $i ...
rwconverter.sh userid=aces/aces@acesdev1 batch=yes source=$i
stype=rdffile dtype=repfile overwrite=yes
done
If it works, u forgot the "ls" in your loop.

Another simple bash script to clean pacman cache

here is a simple script that I have written which cleans pacman cache folder in a way that only the packages which are now "updated" in the repositories, will get removed. This is different from what "pacman -Sc" does. pacman -Sc also removes any package which is not installed, while this script keeps all the packages which are updated whether they are installed or not.
The functionality is some how like what "apt-get autoclean" does in debian.
to use this script you need to run it with "list" or "clean" arguments. you can also use the "help" argument for more help.
I hope it helps

1. `echo -e 'foo\nbar\nbaz'` gets long and unreadable quickly. Instead, use here documents:
cat <<EOF
What should I do?
Valid Argument are "list", "clean" or "help"
EOF
2. Use a case command, looks cleaner:
case "$1" in
list) ... ;;
clean) ... ;;
help|-h|--hep) ... ;;
# Check if the user is sure!
echo "This might take a while based on the amount of cached packages."
echo -n "$MESSAGE(y/n) "
read ANS
if [ $ANS = "y" -o $ANS = "Y" -o $ANS = "yes" ]
then
echo "Processing packages..."
elif [ $ANS = "n" -o $ANS = "N" -o $ANS = "No" ]
then
echo "Exiting on user request"
exit 0
else
echo "Invalid answer"
exit 1
fi
Try:
read -p "hello: " -r
echo $REPLY
And again, `case` should be cleaner in this case.
# Process the packages
cd $DIR #change to cache directory.
pacman -Sl | awk '{ print $2" "$3; }' > $TMPFILE
While you quoted a lot, you left these two out. "$DIR" and "$TMPFILE" should be quoted, otherwise whitespaces will break the code.
for f in $(ls $DIR)
Apart from the same missing quotes, calling `ls` is a waste here. The following is sufficient and (maybe surprisingly) more accurate:
for f in *
How is it more accurate? Run this test script:
#!/bin/bash
DIR=/tmp/foo
mkdir -p "$DIR"
cd "$DIR"
touch a\ b c$'\n'd
for i in *; do
printf '+%s+\n' "$i"
done
printf '%s\n' ---
for i in $(ls $DIR); do
printf '+%s+\n' "$i"
done
Let's not go too far here. Just get the idea.
do
pname=$(file $f | cut -d: -f1) #Produces filename, like: fetchmail-6.3.19-1-i686.pkg.tar.xz"
Calling `file` here is, again, unnecessary. Also, filename of a package can contain ":", e.g., vi-1:050325-1-i686.pkg.tar.xz, which breaks your code.
Don't complicate things:
pname=$f
spname=$(echo $pname | sed 's/-[0-9][0-9]*.*//g') #removes package version: fetchmail
Broken for ntfs-3g-2011.4.12-1-i686.pkg.tar.xz, nvidia-173xx-utils-173.14.31-1-i686.pkg.tar.xz, etc... Something less lousy:
sed 's/$-[^-]\+$\{3\}$//' <<< "$pname"
pver=$(echo $pname | sed 's/.*-$[0-9\-\.][0-9\-\.]*-[0-9\-\.][0-9\-\.]*$.*/\1/g') #using pacman -Qi for all files takes a lot of time.
Although this might work for now, this would break if we had an architecture that starts with a digit, e.g. 686. Something less lousy:
sed 's/$.*$-$[^-]\+-[^-]\+$-[^-]\+$/\2/' <<< "$pname"
if [ $(echo $pver | grep '[^0-9\-\.\-\-]' | wc -l) != 0 ] #checks if package version is alright
then
pver=$(pacman -Qpi $f | grep Version | awk '{print $3}')
fi
Again, calling `wc` here is a waste. Anyway, why is this check necessary at all?
newpver=$(grep -e "^$spname " $TMPFILE | awk '{ print $2 }')
if [[ $newpver != $pver ]]
then
$ACTION $f
fi
done
rm -f $TMPFILE
echo "Outdated packages processed successfully!"
exit 0
The post is getting too long, so so much from me. If there's anything you don't understand yet, read bash(1).
If I sound harsh or anything, don't be discouraged. Just keep reading, keep improving.

Batch rename improvements

While liking the batch rename feature, I'd like to suggest some improvements:
1) The ability to save renaming schemes - eg "standard", "web"
2) Character replacements - eg new filename = first 5 characters of old filename + "dog" + all characters after 16th character of old name
3) Search and replace - eg replace "dog" with "cats"
If any of these aren't clear, I'd happily elaborate.

I second the request for improvements in batch renaming. In my view the "standard" for this function is the Bulk Rename Utility (www.bulkrenameutility.co.uk) by Jim Willsher and Paolo Messina, if I were Adobe I would look at that feature set as the goal.

Simple bash-batch-compiler improvements
