Unix Script -- To Skip killing a specific process

Hi,

By using

ps -aux | awk '/mine/{split($15,a,"/");print $1,$2,a[length(a)]}'

i get the below listed PID's with there corresponding processes.

adm 1522 ABC_Process.tra
adm 1939 GENE_Process.tra
adm 2729 GENE_Archive.tra
adm 3259 xyz_Process.tra

I use

ps -aux | awk '/mine/{split($15,a,"/");print $1,$2,a[length(a)]}' | while read a PID b; do kill -9 $PID; done

to kill the process gracefully.

But from the listed processes i do not want "GENE" processes to be killed, and the rest should be.

Is there a way to perform it in the unix script and print me the output of the same, in which GENE process should not be touched.

Expecting output like :

1522 ABC_Process.tra  is killed gracefully
3259  XYZ_Process.tra is killed gracefully

Any alternative ways are most welcome

What do you mean GENE processes?

Where do the words "is killed gracefully" in your expected output come from? There's nothing graceful about "kill -9".

Since you have already concocted a somewhat overly-complicated command (which I'm sure someone will take the time to simplify), you could simply add a grep -v GENE before the while

ps -aux | awk ... | grep -v GENE_ | while ...

kill -9 kills a process abruptly
to cleanly kill a process kill -15 is used.

the difference between the two is,
kill -9 murders the process [doesn't care if it has any unfinished job], whereas
kill -15 requests the process to die hence, the process can finish it's unfinished jobs and die peacefulle [RIP :D]

you can google more about kill signals

Or you could just read the manual page: signal(3)
