Searching for a string in file and replacing it could be done very easily with "sed", look at the forum base for various examples. Why you want this in perl ? You're gonna have to open the file, search / grep for string, then replace and close the file - uncecessary long.

GZGREP(1) General Commands Manual GZGREP(1)
NAME
gzgrep, gzegrep, gzfgrep - search possibly compressed files for a regular expression
SYNOPSIS
gzgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
gzgrep 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 gzgrep is invoked as gzegrep or gzfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, gzgrep
uses it as the grep program to be invoked. For example:
for sh: GREP=fgrep gzgrep string files
for csh: (setenv GREP fgrep; gzgrep string files)
