Hi, I'm using delayed_job to run jobs, with new jobs being added every minute by a cronjob. Currently I have an issue where the rake jobs:work task, currently started with 'nohup rake jobs:work &' manually, is randomly exiting.

I have a bash script that cuts out a section of a logfile between 2 timestamps, but because of the size of the files, it takes quite a while to run. If I were to rewrite the script in Perl, could I achieve a significant speed increase - or would I have to move to something like C to accomplish this? #!/bin/bash if [ $# -ne 3 ]; then ...
I've done something to break my Bash Shell Prompt in OS X (10.5.7) Terminal. This is the PS1 that I had configured: PS1='\[\e[1;32m\]\h\[\e[0m\]:\[\e[1;34m\]\w\[\e[0m\]\$ ' As far as I can tell I have the color commands escaping correctly. However when I scroll up and down in my command history I often get line wrapping issues if the...
I have this bash script on the server that runs every hour, via cron. I was perfectly happy, but now the user wants to be able to configure the frequency through the web interface. I don't feel comfortable manipulating the cron configuration programmatically, but I'm not sure if the other options are any better. The way I see it, I can...

I need to write a OS X login hook script that is aware of the users current home folder. Since the users are Active Directory users, their home folders are not stored in /Users so I can't simply hard code the full path. Since the login hook is run by a daemon as root, I can not use $HOME, ~, etc either. The only piece of info I have i...

I was thinking of using inotifywait to watch the original folder where the original folders are in, then when ever it detects that a folder has been deleted, then delete the same symbolic link in the other folder. So my question is, is that the best way? Or are there better ways to delete a symbolic link when the original folder gets de...
I have some long running scripts with breaks requiring input/interaction to continue but when I switch to another window I'd like to be notified (by sound) that a task is complete and now awaiting input. I would prefer to be able to play an audio clip (*.mp3, *.ogg, etc.) but wouldn't care if the only solution is to make the PC Speaker ...
Hi, I have the below awk command-line argument and it works aside from the fact it performs the print argument on the entire file (as expected). I would like it to just perform the formatting on the last 10 lines of the file (or any arbitrary number). Any suggestions are greatly appreciated, thanks! I know one solution would be to ...
