ZGREP
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 compressâed or gzipâed files. All 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 neces-
sary 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)

Performance Tuning for firefox
Firefox has Memory issues. If the browser is kept open for a while, even if I close all tabs except one Firefox doesn't clear the memory that it occupied. In my case I kept the browser open for more than a day; 2 windows with 4 tabs each. From the second day onwards it takes up more than 512Mb of memory and even typing becomes slow.
I found this article that explains how to fix the memory leak issue in firefox. Its basically tuning for better performance.
Hope this helps you.
