Your script works - I added an infinite loop so I have that script constantly running in the background. Started it with nohup & in the background and tried to start that script again:

Code:

root@isau02:/data/tmp/testfeld> ./loop.ksh
exit code: 0
script name: ./loop.ksh
The process ./loop.ksh is already running. Aborting the current instance of the job ./loop.ksh
root@isau02:/data/tmp/testfeld> ps -ef| grep -i loo
root     29647 32139  0 09:25 pts/0    00:00:00 /usr/bin/ksh ./loop.ksh
root     29685 29659  0 09:26 pts/1    00:00:00 grep -i loo


root@isau02:/data/tmp/testfeld> cat loo*
#!/usr/bin/ksh

typeset -i A=0
SCRIPT_NAME=$0

if [ `ps -ef | grep " ${SCRIPT_NAME}" | grep -v "grep" | wc -l` -gt 1 ]; then
        echo "exit code: $?"
        echo "script name: ${SCRIPT_NAME}"
        echo "The process $0 is already running. Aborting the current instance of the job $0"
        exit 1
fi

while (( $A != 1 )); do
        sleep 1
done

exit 0

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.
