Top Forums Shell Programming and Scripting Help with multiple instance script checking Post 302370137 by TonyFullerMalv on Tuesday 10th of November 2009 01:22:45 PM

The code:

Code:
ps -ef | grep process | grep -v grep

Is quite normal for what you are trying to achieve, not sure what the "a" parameter is adding?
I would compare what the output from "ps -eaf" looks like on each server and make sure they are identical.

Another method to achive the above (not so simple whjen the process name is a variable) is:

Code:
ps -ef | grep [f]irefox

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. AUTHOR
