Doubt about if conditions
Hi folks,

Please confirm below code is fine or not. I mean to say confirm if conditions are fine or not, because i need to test it on live server but before this i need confirmation. Below script first check the status of database and tell us database is up and then stop the database but after that it again check database is down or still up.

Code:
echo "Checking DB Status"

DBSTATUS=`ps -ef |grep ora_pmon_DB1 |grep -v grep |awk -F " "  '{print $8}'`

if [ "$DBSTATUS" = "ora_pmon_DB1" ]
then
echo "$DBSTATUS is up"

#commands stop databse

DBSTATUSF=`ps -ef |grep ora_pmon_DB1 | grep -v grep |awk -F " "  '{print $8}'`
if [ "$DBSTATUSF" = "ora_pmon_DB1" ]
then
echo "$DBSTATUSF is Down - FAILED"
else
echo "$DBSTATUSF is up - SUCCESSFUL"
fi
else
echo "$DBSTATUSF Down - FAILED"
fi

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.
