and i want to kill that script with only script name.....
so what's the solution..

for your info
my script name is "testscript" n it contains "sleep 100"

If your system has pidof, use that. Otherwise, the customary solution is to run grep on a ps listing of your processes, and use that to find the PID to pass to kill. However, a naive attempt will have the problem that it will find itself in the process listing, and commit suicide instead of kill the intended target. The proper workaround for that is to use a regular expression which does not directly match itself as the search string.

Unfortunately, the options and output format of ps varies from one system to another. The following works for me on a recent version of Ubuntu.

The use of [t] instead of just a plain t is the workaround for the "script will kill itself" problem. The use of xargs -r prevents kill from being run at all if there are no matches (there would only be a warning message about running kill with no arguments, so that is not a very fatal problem).

The option t and the field numbers $1 and $5 might need to be changed for your system. If you google for a similar solution for your particular platform, look out for the problems outlined above. For stylistic reasons, a single awk script should be preferred over what is affectionately called Useless Use of Grep.

If you are using Linux, you can use the killall command to kill a process using the process name(s) (not the PID).

See, for example: killall(1): kill processes by name - Linux man page

Se all, pkill: http://linux.die.net/man/1/pkill

I got the solution
Use
kill `ps -C test.sh -o pid=`

On Linux, you could simple type:

killall testscript

Something simple:
killall procname

Another way:
inside your script, create a temporary file that holds the current pid of your script. When you wish to terminate the process, use that as such: kill -9 `cat pidfile`

If you want something very specific and accurate:
- setuid() to another user which only runs that process (script)
- pkill -9 -u youruser
You can also use pkill to kill all processes using a certain terminal pkill -9 -t pts/1

(But don't use kill -9 if you don't know exactly what you are doing.)
