how to get start time of a running process
I am trying to see if a process is running what was its start time.

here is the code that I am using

Code:
if [ `ps -elf | grep batch_output_x | grep -cv grep` = 0 ]
then
    echo 'Gateway output processing started.' 
else       
 VAR=$(ps -ef | grep batch_output_x )
...

fi

now the problem i see is when the process is running i get two lines like this

Code:
splgwdv 29898 29893  0 11:01:20 pts/ta    0:00 grep batch_output_x
splgwdv 29827 18757  0 11:01:08 pts/tb    0:00 /usr/bin/ksh ./batch_output_x.sh

I need to get the second line time (11:01:08) as the first line is the current time.

Why is that line giving me two results
and how do I get the second line?
because when I am doing this

Code:
        VAR=$(ps -ef | grep batch_output_x )

        FTP_HOUR=$(echo $VAR|cut -c23-24)
        FTP_MIN=$(echo $VAR|cut -c26-27)
        FTP_SEC=$(echo $VAR|cut -c29-30)

        echo "Time: $FTP_HOUR:$FTP_MIN:$FTP_SEC"

its returning Time: 11:01:20

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.
