How to use Getpid

[crystal28]

Please can anyone give me the syntax in cshell how to get the value that returns from the function getpid,so that i can use it to kill a process

 

[Chapter11]

getpid is a C library function, not a command available to csh.

If you want to find PIDs from a shell script, use "ps".

will it be like

set v_pid=ps

In ksh , a shell veriable $$ contains the id of the current process .

So ,

kill $$

will kill the currecnt process , which generally does not look like a logical task .

If u want to kill some perticular process ,

ps -e -o "%p %y %a"

will give u only the process id , terminal name and process description . grep or with some logic select your processes to be killed and then use the id to kill processes .
