Top Forums Shell Programming and Scripting Inconsistent `ps -eaf -o args | grep -i sfs_pcard_load_file.ksh | grep -v grep | wc -l` Post 302911248 by Chubler_XL on Wednesday 30th of July 2014 05:04:49 PM

As Corona688 pointed out, try and use a PID file - It's more portable reliable and best practice.

As for your ps issue, avoid using -f and -o args these two arguments are at odds with each other -f is for full listing and -o is limiting to specific list of arguments.

One popular way to avoid counting the grep command is to use an RE that doesn't match itself for example:

Code:
ISRUNNING=`ps -e -o args | grep -i [s]fs_pcard_load_file.ksh | wc -l`

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
