sqn · 07-09-2003, 04:04 PM

I want to make a script that will capture/serch for a specified string in the stdout of a program and put it in a file:
example
i give a ping command to a host and the reply with 0% pachets lost/100% pakets lost i need to put it in a file witch will b emaild to later. The problem is how can i capture that reply?

Thx in advance

PS I use pure shell script

This is too simple I suppose :

ping 192.168.1.1 > /root/grepin
grep -n "packet loss" /root/grepin > /root/grepout

If it's not flexible enough you could go with variables instead.
