bzgrep
BZGREP(1) General Commands Manual BZGREP(1)NAME
bzgrep, bzfgrep, bzegrep - search possibly bzip2 compressed files for a regular expression
SYNOPSIS
bzgrep [ grep_options ] [ -e ] pattern filename...
bzegrep [ egrep_options ] [ -e ] pattern filename...
bzfgrep [ fgrep_options ] [ -e ] pattern filename...
DESCRIPTION
Bzgrep is used to invoke the grep on bzip2-compressed 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 necessary and fed to
grep.
If bzgrep is invoked as bzegrep or bzfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, bzgrep
uses it as the grep program to be invoked. For example:
for sh: GREP=fgrep bzgrep string files
for csh: (setenv GREP fgrep; bzgrep string files)
