Top Forums Shell Programming and Scripting How do I search a File for a string exact match Post 302219383 by era on Tuesday 29th of July 2008 01:20:51 AM

Only coincidentally, actually. The addition of the square brackets is probably not correct, if I managed to understand your requirements.

You are trimming whitespace with tr -d ' ' -- are we to infer that spaces are allowed in the file before or after the match, on the same line?

Code:
grep "^ *$l_string *$" $l_tmp_file

If you don't want to allow spaces, remove both occurrences of space, asterisk.

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 is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep. If no file is speci- fied, 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 zgrep is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. For example: for sh: GREP=fgrep zgrep string files for csh: (setenv GREP fgrep; zgrep string files) AUTHOR
