I'm not sure why I'm getting the permission denied, and also I can't see whats wrong with line 5.

IIRC you need spaces
if [ "foo" = "foo" ]; then
between '[' and another character.
Edit: Got it.
current_state=cat /home/phil/.screen_state
This is plain wrong. I get 'Permission denied' too.
Try
current_state=$(cat /home/phil/.screen_state)

[solved]Need help with a bash script for MOC conky artwork.

I need some help with a bash script for displaying artwork from MOC.
Music folders have a file called 'front.jpg' in them, so I need to pull the current directory from MOCP and then display the 'front.jpg' file in conky.
mocp -Q %file
gives me the current file playing, but I need the directory (perhaps some way to use only everything after the last '/'?)
A point in the right direction would be appreciated.
thanks, d

You should also quote the variables and output in double quotes to make the code robust, e.g.
filename="$(mocp -Q %file)"
dirname="${filename%/*}"
cp "$dirname"/front.jpg ~/backup/art.jpg
Without the quotes, whitespace will break the code. Even if you don't expect whitespace in any of the paths, it's still good coding practice to include the quotes imo.
thanks for the tip.
here it is, anyhow:
#!/bin/bash
filename=$(mocp -Q %file)
dirname=${filename%/*}
cp ${dirname}/front.jpg ~/backup/art.jpg
then in conky:
$alignr${execi 30 ~/bin/artc}${image ~/backup/art.jpg -s 100x100 -p -3,60}
thanks for the help.

Help with simple Automator script

I have a simple Automator script for updating a specified folder with files from another folder. It consists of only two actions:
1. Get Folder Contents (from the folder I drop on the Automator executable).
2. Copy Finder Items.
I left the option "replace existing files" unchecked because there's no point in replacing a bunch of files that already exist (we're talking about 4000-5000 files in the source folder). I assumed that meant to ignore any existing files but, on the contrary, I found out that the script is copying duplicates of all the existing files -- making my target folder about 9000 files strong!
How do I get a command into the middle of this script to restrict the Copy Finder Items command to files that do not already exist in the target folder? (It would be even nicer if it could check for files that are older than the files being copied and actually replace (only) those as well.)
Any ideas?

If you need the Terminal window to stay open, then you're looking at scripting Terminal. You can do this with Automator's run applescript action, or you can just use Script Editor (in Applications > AppleScript). Either way you will need to save the workflow/script as an application and drag it to your Login Items (in System Preferences > Accounts).
click here to open this script in your editor<pre style="font-family: 'Monaco', 'Courier New', Courier, monospace; overflow:auto; color: #222; background: #DDD; padding: 0.2em; font-size: 10px; width:400px">tell application "Terminal"
activate
set commands to "cd /Users/lenny/ventrilo/
/Users/lenny/ventrilo/ventrilo_srv"
do script commands in front window
end tell</pre>

While my `mv` code will throw an error the error will not stop the moving of the files, you'll just get 26 messages about being unable to move the directory to itself. I could probably find a way to avoid this that doesn't require the use of find(which I personally dislike) or a second dir, probably just using a file prefix like "_" or something. It would only be a small edit:
#!/bin/bash
for I in {a..z}; do
echo "Moving $I";
mkdir "_$I";
echo "mv $I* \"$(echo $I | tr [:lower:] [:upper:])\"* _$I/";
# mv $I* "$(echo $I | tr [:lower:] [:upper:])"* "_$I/";
mv "_$I" $I
done
well, i have to politely disagree: one, invoking find once is much better IMHO than mv with tr in a subshell. and two, my ./sorted/ idea adds one additional mv command and one additional rm command where you're _$I suggestion added 26 additional mv commands.... just sayin'
but we could also paint the bikeshed blue. .
anyways, i think the OP's got more than he bargained for, hopefully we'll see a [SOLVED] on this one soon.

[SOLVED] Help with systemd .service script

Hello,
I have been using ArchLinux (ARM version) on some “plug computers” for over a year and love it. Recently I forced myself to move to systemd by upgrading all my computers from scratch. I migrated all my applications and learned new ways of doing things but am having trouble with one last migration. I run a c++ communication program that monitors a TCP port for traffic. In the past I started this program (daemon) from an entry in rc.conf. I have read all I can about systemd’s new approach to starting daemons (https://wiki.archlinux.org/index.php/Systemd and https://wiki.archlinux.org/index.php/Systemd/Services)
So far I created what I thought is the correct systemd .service file listed below.
[Unit]
Description=EQBCS
After=network.target
[Service]
Type=simple
ExecStart=/home/public/EQBCS/eqbcs -p 12947 -d &> /dev/null
[Install]
WantedBy=multi-user.target
I put this file in /usr/lib/systemd/system/eqbcs.service. I then ran the following commands in the following order:
systemctl daemon-reload
systemctl enable eqbcs.service (created a link in /etc/systemd/system/multi-user.target.wants)
systemctl start eqbcs.service
Here is output from systemctl (status)
eqbcs.service loaded failed failed EQBCS
I thought this would start the service but no luck. I also thought maybe a reboot would work but no luck. I verified I can start the daemon manually if I run /home/public/EQBCS/eqbcs -p 12947 -d &> /dev/null from the command line.
I think I am close, but after several hours of looking at examples of .service files and other posts, I am at a loss. I am not one of those types who posts a question without taking the time to read the wealth of information on these boards, but I am truly out of ideas and can’t figure out what to do next. I sincerely could use some help/advice.

Thank you for the suggestions, I believe I am getting closer to success. When I run systemctl start eqbcs.servcie it starts the service but the only way I can get out of systemctl is to ^c out.

Help with a bash script, please :)

Arkane wrote:I didn't know about disown before, but if I understood things correctly it will make the program we just started independent of the shell running the script, so that it keeps running when the shell exits.
Yeah, the shell keeps track of its jobs, and when the shell exits, it sends a SIGHUP signal to its jobs. The "disown" command tells the shell not to bother (and stop keeping track of this job), allowing you to close the shell without disturbing the running jobs.
You can get this effect other ways also.
Here is a better version of the script:
#!/bin/bash
CMD='mplayer -playlist http://www.emapdigitalradio.com/emapdigitalradio/metafiles/kiss105.asx'
MPID=$(ps u -C mplayer | grep "$CMD" | awk '{print $2}')
if [ -z "$MPID" ]; then
#echo -n starting kiss...
$CMD &>/dev/null &
disown %1
#echo done
else
#echo -n stopping kiss...
kill $MPID
#echo done
fi
This one is less ambitious in killing all instances of mplayer. Uncomment the "echo" lines if you want some feedback.

Need help with simple python script (renaming and moving folder)

I have this script for use with sabnzbd, what it does is rename all folders in the desired directory, replacing any spaces with dots (example: Movie 2011 HD -> Movie.2011.HD).
#!/usr/bin/env python2
workdir = '/media/stuff/movies' #### CHANGE this line to your movie directory
for path, dirnames, filenames in os.walk(workdir):
print "path:", path
for dirname in dirnames:
if dirname.find(' ') > -1 :
# Yes, a space in the directory name, so replace it:
newname = dirname.replace(' ','.')
fulldirname = path + '/' + dirname
fullnewname = path + '/' + newname
print "Rename" , fulldirname, " ", fullnewname
os.rename(fulldirname, fullnewname)
What I would like it to do is 1. rename only the movie I run the script on (instead of /media/stuff/movies as above, the entire movie folder), and then 2. move the movie into /media/stuff/movies. Or vice versa! (I'd just prefer not to have it run on the entire movie directory).
Appreciate any help!

Just my two cents:
I would not use walkdir but as usual a combination of find and python.
A simplified version of the script could look like this:
#!/usr/bin/python
# -*- coding: utf8 -*-
import os, shutil
# Define target dir
target_dir = "/media/stuff/movies/"
# Loop through all found files
for source_file in os.popen ("find ."):
# Remove \n
source_file = source_file[:-1]
extension = source_file[-3:]
# Only process video files
if (extension == 'mkv') or (extension == 'avi') or (extension == 'mp4'):
target_file = source_file.split('/')
target = target_file[len(target_file)-1]
target = target.replace(' ','.')
shutil.copy (source_file, targetdir + target)
Of course you might first want to print out instead of really copy files.

Help with Simple Perl script, its sooo simple!!!

i know this isnt java but i need to know how to do this for class for this class is a prerequisite to the java servlets class. Please help, i am just starting to learn perl and this error doesnt make sence to me.
this is my error...
Unquoted string "cnt" may clash with future reserved word at c:\inetpub\wwwroot\ANDwebs\cgi-bin\form2.pl line 19.
Can't modify constant item in postincrement (++) at c:\inetpub\wwwroot\ANDwebs\cgi-bin\form2.pl line 19, near "cnt++"
Execution of c:\inetpub\wwwroot\ANDwebs\cgi-bin\form2.pl aborted due to compilation errors.
this is my code...
#!/usr/bin/perl -w
print "Content-type: text/html \n\n";
read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'});
@fields = qw(fullName compName add1 add2 city state zip email dayPhone evePhone fax);
@pairs = split(/&/, $buffer);
@values;
$cnt;
foreach $key (@pairs)
($name, $value) = split(/=/, $key);
$value =~ tr/+/ /;
$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C",hex($1))/eg;
$value =~ s///g;
$values[cnt++] = $value;
foreach $key (@fields){
print "$key";
}

$values[cnt++] = $value;cnt should be $cnt.
Also remember to always put:
use strict;
at the beginning of all your Perl programs!!!
However, the fact that this is for a class that is a prerequisite for a Java class doesn't make this a Java question. Please post your Perl questions to the comp.lang.perl.* newsgroups.

Help With Simple if Script??

Hi
I have a text field named literature. In the text box i have Not Required as the default.
At the bottom the form i want to create something that tells shipping Literature Required Yes or No.
Basically if they leave the field literautre no touched so it says Not Required the bottom would say No but if they change it to anything else it would say Yes.
I tried putting in a text field at the bottom of the page called litreq and tried to add in a script but i cant get anything to work.
Here is one i tried.
form1.#subform[0].#subform[1].litreq::initialize - (JavaScript, client)
if
literature="Not Required"litreq
="No"
else
litreq
="Yes"

Move the script to the exit event on literature and change the script to....
if (literature.rawValue == "Not Required") {
litreq.rawValue = "No";
else {
litreq.rawValue = "Yes";

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"

if [ "`echo \" $NAMES \" | grep \" $CHOICE \"`" ]; then
echo "this is how you do it"

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

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]>

# 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

# Update each of its subdirectories

Help with simple script

I was wondering if someone could help me with a simple bit of action script 3. I need to make a movie clip (single_mc) disappear when the user clicks on the mouse (stop_btn). Here’s what I have so far.
function setProperty(event:MouseEvent):void
single_mc.alpha=0;
stop_btn.addEventListener(MouseEvent.CLICK, setProperty);
Also I was wonder if you could recommend an Action script 3 book for me. I would like one that is not a training book, but has situations and then the script written out. For example: I click a button and a movie symbol disappears from the stage. I am a graphic artist, that from time to time, needs simple interaction in flash, but cant justify the time to learn the script.
Thanks for your time

use the snippets panel to help with you with sample code for basic tasks.
function setProperty(event:MouseEvent):void
single_mc.visible=false;
stop_btn.addEventListener(MouseEvent.CLICK, setProperty);

Out of curiosity i put the ALL parameter and that did not work either o,0 Either something has gone very wrong or Im in need of a lesson in sudo'ing. Can someone help? btw i looked at tutorials on the web and from what i can see im doing everything right. and before you suggest i checked that rkhunter is in /usr/bin/. here is my sudoers file.
EDIT: removed the comment in the first line i did not have that there when i ran it.

rkhunter is not is /usr/sbin i checked specifically for that before i tried doing it in sudo. Its output is
bash:/usr/bin/rkhunter: Permission Denied
I tried your suggestion xyne with no luck. I double checked and im in the wheel group. The problem is, it is important I see the output the of rkhunter, if i didn't it would be pointless, and annoying to check the log. Also rkhunter has breaks in its output that require me to press enter to continue. So it will never finish if i dont see it. My plan is to have pop up in a terminal in front of me do its job, finish, and thats it. I was thinking I can use a simple shell script with the command. "urxvt -e rkhunter -c" Then run that shell script as a cron job. Can I get the results I want in the root crontab? Im also new to cron as well. Ive been using linux for while and I have little experience with both of these programs. Its time to learn them.
Thanks for your effort so though,
