Still it might be worthwhile to step back and reconsider the entire approach. The comments in your other thread, esp.
this post and post#11 there still apply. The entire thing might be doable in one single
awk script.
The below code fails as there will be no file having such pattern. $i is not available in the log files at start of the day till evening.in that case the below grep fails.
grep $i /home/lim/updates/logs/log*$d*
If this fails automatically the next two grep/awk fails.
Currently the working condition for me is using if and based on that proceed with script.

How do I evaluate the result of a command assigned to a variable??
Example:
var1=`cmd`
rc=$?
rc will be the result of the assignment rather than cmd since it executes after. How do I evaluate the result of the command itself?

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.
