Confusion with PS
Hello All,

I have a problem in counting number of process getting run with my current script name..

Here it is

Code:
ps -ef | grep $0 | grep -v grep

This display just one line with the PID, PPID and other details when i print it in the script.

But when I want to count the numbers in my script , just like below, it comes out as 2... Whereas only one process is running..

Code:
count=$(ps -ef | grep $0 | grep -v grep | wc -l)
echo $count

My mind completely gone blank, help me here..
Help me how I will get my script to print the correct number of Process running with its name. Thanks.

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.
