I have a script which builds a project and then runs junit tests. However, if the build fails, the junit tests fail with the same error message.Therefore the command which runs the junit tests should only be executed if the build was successful.

I want to loop through the folders and check if they end with *_p1 or *p2. If a given folder ends with *p1, I want to cd to that folder and manipulate certain files in that folder. If the folder ends with *p2, I want to perform different manipulations on certain files.

View 2 Replies View RelatedWhen running a program that has infinite loops in the terminal , how to bring back the command prompt ? ( I'm using Fedora core 5 )
View 7 Replies View RelatedI want a quick and simple way to execute a command whenever a file changes. I want something very simple, something I will leave running on a terminal and close it whenever I'm finished working with that file. Currently, I'm using this: while read; do ./myfile.py ; done And then I need to go to that terminal and press Enter, whenever I save that file on my editor. What I want is something like this: while sleep_until_file_has_changed myfile.py ; do ./myfile.py ; done
Or any other solution as easy as that. BTW: I'm using Vim, and I know I can add an autocommand to run something on BufWrite, but this is not the kind of solution I want now. Update: I want something simple, discardable if possible. What's more, I want something to run in a terminal because I want to see the program output (I want to see error messages).

View 2 Replies View RelatedI am working in a CentOS environment with numerous CentOS machines. Currently there are multiple developers that each have their own login/home directory and then for various admin tasks we all share a single super user account.
The problem
I have a number of aliases, variables, functions, and settings that exist in my personal login's .bash_profile. None of these are available in the shared super user's .bash_profile. My current work around is that everytime I sudo in as the super user and I re-execute my .bash_profile from my personal user's home directory. I am not allowed to edit the init stuff for the super user
The Question
Is there any way I can automate my sudo sequence such that it will execute my personal .bash_profile after I've executed sudo without requiring me to edit the super user's bash init stuff?

My laptop has a dead battery. Even when it's fully charged, if the power cable is pulled out it only lasts for about 4 minutes before it dies. I'm running Ubuntu Lucid Lynx 32-Bit. What I want to do is create some sort of script or program that will immediately set my computer to go into hibernation once it detects that the power cable has gone dead. I'm willing to look into all ways of doing this. I can program in C, but I'm not familiar with the API used to manage Power Management in Linux.

On my ubuntu I have a command pm-suspend, which puts the computer to sleep. It has to be run with sudo. Since it is inconvenient to be forced to type the password every time I want my computer to sleep, I thought maybe there's a way around it. Naively I thought that if I'd create a script as root, that invokes pm-suspend, and then let anyone execute that script, I could run that script as my own user and then that script would be considered run by root and hence be allowed to run pm-suspend. Obviously that didn't work. The root-check procedure in pm-suspend still found out that the original executor was someone different from root.
Still I think something similar (although slightly more elaborate) should work.I'm thinking about the process that allows the user to mount hard drives for example. Normally root is required, but it is somehow bypassed by the gnome utility mounting.

I have a big bash script ,its goal is to download movie one by one . But I often get into a problem: if this script is executed in cron,it often does not completely download the movie.I often find the movies it downloaded are several KB while the movie is actually 20MB.So I think it is because it did not wait for finishing one task ,and jump to download another.So I want to know ,is there a way to force the bash script to wait until one movie downloaded completely and then start to download another movie ?
