you use an treatment on every line but you took only the first line. It's more logical to put the head -1 before the awk treatement. Moreover the grep has the option "-m x" which stop reading file when the x patterns are found.

so the code should be :
Code:
ACTIVE_PSE_COUNT=`grep -m 1 'Current number of Active Requests to the PSE'  /home/xmp/bin/radstats_output.txt | awk '{print $NF}' `

I do not want the last letter "A" here, because of which it does not reastar the process. Please advice.
Code:
ACTIVE_PSE_PROC_1=`xms show pr PRESENCE-STORE.1.* |awk '{print $1 $3}' |grep "A" |tail -1`

awk is a powerful tool, if you use a simple grep you must filter lines with awk :
For your code :
Code:
ACTIVE_PSE_PROC_1=`xms show pr PRESENCE-STORE.1.* |awk '$3 ~ /A/ {print $1 $3}' |tail -1`

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.
