When I create a Automator action in XCode using Bash, all files and folder paths are printed to stdin. How do I get the content of those files? Whatever I try, I only get the filename in the output. If I just select "Run shell script" I can select if I want everything to stdin or as arguments. Can this be done for an XCode project to? ...
I've tried parsing a list of users currently connected via SSH to a server, but the results are very irregular, so I was forced to simply do: $users = shell_exec('who'); echo "<pre>$users</pre>"; Is there a better way to parse the output of who in the command line before I let PHP mess around with it? I want it in an array which conta...
I'm writing a simple program to run through a bunch of files in various directories on my system. It basically involves opening them up and checking for valid XML. One of the options of this program is to list bad xml files. This leads me to my question. What the best output to format this for use with XARGS. I thought putting each ...

I know there are a lot of things like this around, but either they don't work recursively or they are huge. This is what I got: find . -name "*.so" -exec mv {} `echo {} | sed s/.so/.dylib/` \; When I just run the find part it gives me a list of files. When I run the sed part it replaces any .so with .dylib. When I run them together t...

I want to redirect FULL output of my program to a file (including Exceptions) in bash. I can't change content of class. I run it like that: java -Djava.security.manager -Djava.security.policy=JLPPolicy -Xmx16M -Xms2M -cp /var/tomcat/bin/ Main > File Exceptions are send to console, which is bad for me. Can I do something with it? ...
When using the find command, why is it that the following will successfully ignore hidden directories (those starting with a period) while matching everything else: find . -not \( -type d -name ".?*" -prune \) but this will not match anything at all: find . -not \( -type d -name ".*" -prune \) The only difference is the question mark...

lets say we were to use standard bash terminology to write a for loop which loops srm to securely erase a item on your drive. Now lets say we set it to iterate 10 times, after it is done the first iteration, How can it still work on the file? The file should no longer exist, so how can It erase it? Not a question specific to srm, anyt...
Whats an easy way to convert 00:20:40.28 to seconds with a bash script? (Split seconds can be cut out, it’s not essential.) ...
I'm not a scripting expert and I was wondering what was an acceptable way to run a script for at most x milliseconds (and yet finish before x milliseconds if the script is done before the timeout). I solved that problem using Bash in a way that I think is very hacky and I wonder if there's a better way to do it. Basically I've got on...
I am trying to run this script which changes my desktops background to a random picture in a directory. It works from the command line, and the cronjob gets run (added output and it gets spit out to a log file), but I can't get it to change my background. Here's my current line (set to run every minute for testing). 01 * * * * username ...
