ps l

Hi

When I kick off a script I then need to check whether or not it is running (in another sesssion) by another script.

ps -fu$USER | grep scriptname.sh | grep -v grep |wc -l

Most of the time it is ok but if you run above command immediately after kicking off the script then you can get more than one process returned. Why is that ?

Think of changing command above to use ps l command but do not understand what the first column represents. It is F for field but I do not understand how to understand the results in the F column.
ie what does 200001 mean

Any help much appreciated.
Cheers

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  is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep.  If no file is speci-
       fied, 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  zgrep  is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep.  If the GREP environment variable is set, zgrep uses
       it as the grep program to be invoked. For example:

	   for sh:  GREP=fgrep	zgrep string files
	   for csh: (setenv GREP fgrep; zgrep string files)
