shell script on the command line

[jerehart]

Hey I am trying to watch a file being written to pipe it into grep looking for a string and kill a process on that string. this is what I am doing:

tail -f some.file | grep ERROR | kill #PID

but it kills the process right away. Any ideas or need more from me?

hi

i don't think you can do that with tail -f and greping it with error...

what you need is a cron job which is activited a certain time to check for Error and then killing it...not a simple script like that.

hope that helps,

It helps. I was trying to be lazy and hoping I could. I was afraid I would have tobulk it up. So it was not the answer I wanted but the one I thought I would get Thanks Hui

jerehart,

That sounds quite do-able, two questions:

1 - What's the format of the file and where do you get the PID from?

2 - What tools do you have? Perl? Awk? Ksh? Mike

Mike,

the file format is just a text ascii file nothing special. I get the PID from
ps -elf | grep <The process name>

I would use perl myself I like it a lot more than anything else. I have awk and tcl available but don't like them too much but could do it in all.
