Programming

Hi All,
I want to find if a certain exe is running and if it is running i want to stop the execution of this exe (the exe has been created by me) on solaris.
What are the unix command i need to use and can i put these comand in a shell script or create a new exe to do this task (i would prefer an exe cos i need to call this from a browser based frontend, i m not using cgi.)

Thanks in advance

To kill a process, not a program, you need to know the process id or pid. Manually, you might do "ps -ef | more" and look at the output until you find the process in question. Then you do "kill 123" or whatever. A process can detect this and shut itself down. If that doesn't kill it, then "kill -9 123" is in order.

Since you wrote the program, one useful trick is to have the program write its pid to a file, which by tradition would be called myprog.pid or something. Then you do "kill `cat myprog.pid`".

All of this is possible in C via kill() and getpid().

There are man pages on all of this stuff. So become familiar with commands like:
man -k kill
man -s1 kill
man -s2 kill

But also, if you don't know how to kill a process, I must say that it's premature to writing in C on Unix. I would advise you to read a book on unix programming.

Finally, our rules state: By simply putting "kill" in as keyword, you would find lots of threads about killing processes.

Hi Zing,

Looking from inside your program you could do the following :

fuser -fu </file/to/program/>

to find any running processes, accessing this file (program)

or

ps -ef | grep <name of program> | grep -v grep | awk '{ print $2}'

This is a possibility too, to find a running process. As you understand this will have to be translated into C. To be honest, I am not this far in Programming C, but it might get you a little closer to your solution.

Please don't use the term exe anymore. It sounds too much like .exe .An executable would be preferred

i have to stop a program from running please i want to know how to do this

If you mean you want to terminate the program, please read the above thread. If you want to halt it but not kill it, please make a relevant thread instead of asking new questions in an unrelated one.
