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  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.
