I'm piping the results of a tcpdump into a shell script and want certain commands executed (specifically the firing of an SNMP alert) based on a grep for certain contents in the output of tcpdump.
For example, I have
However, this simply waits for a string that matches ttl64 and then waits for one matching ttl128, I need it to continually spot matches and fire the packet based on which is matched. Any ideas for a better script?
I need to have an if statement in a script to run if there are certain processes running. Easiest way I can see to do this is to run a ps and grep the results based on what I am looking for:
$ ps -ef | grep wtrs

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
