The following code for search a pattern in file name (or entire file name) and look at its size, code is derived from an ebook about scripting. It is working in HP Unix but I am unable to run in Linux (Ubuntu) Please advise me what is wrong for Linux?
And besides , how can I get rid of errors in case of the file is not available?
The grep command doesn't search the pattern in the file name, the search is made in the file content.
Another point about grep, the right syntax is :
You can replace the grep command by an expr command :
or if you are using ksh or bash :

Dear Help,
Is it possible to continue the loop by going to the next available value, if the 'expected value' is not found. I have a list of values which might not get incremented by fixed value and hence the loop could break and the script could terminate.
Any suggestion is appreciated.

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.
