Can't grep name of process
Hi

I am trying to grep the name of the user running a specific process on one of my systems.
Code:
[apm@ccbapprts1 enterprisemanager]$ ps -efl | grep 'Introscope_WebView.lax' | grep -v grep| awk '{print $3}'
[apm@ccbapprts1 enterprisemanager]$ ps -efl | grep 'Introscope_WebView.lax'

0 S apm      14572 17108  0  80   0 - 28164 pipe_w 10:31 pts/4    00:00:00 grep --color=auto Introscope_WebView.lax

I would presume that would return "apm" but nothing appears

When I do the same code on a different unix server it works as expected:
Code:
[casupport@wycvlapph048 ~]$ ps -efl | grep 'Introscope_WebView.lax' | grep -v grep| awk '{print $3}'
50011
[casupport@wycvlapph048 ~]$ ps -efl | grep 'Introscope_WebView.lax'
0 S 50011      635 32387  0  80   0 - 25830 pipe_w 10:25 pts/0    00:00:00 grep Introscope_WebView.lax

Why is this?

Cheers
Alex

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.
