.SH NAME
bzgrep, bzfgrep, bzegrep \- search possibly bzip2 compressed files for a regular expression

.B bzgrep

.BI  [\ -e\ ] " pattern"
.IR filename ".\|.\|."
.br
.B bzegrep

.SH DESCRIPTION
.IR  Bzgrep
is used to invoke the
.I grep
on bzip2-compressed files. All options specified are passed directly to
.I 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
.I grep.
.PP
If
.I bzgrep
is invoked as
.I bzegrep
or
.I bzfgrep
then
.I egrep
or
.I fgrep
is used instead of
.I grep.
If the GREP environment variable is set,
.I bzgrep
uses it as the
.I grep
program to be invoked. For example:

    for sh:  GREP=fgrep  bzgrep string files
    for csh: (setenv GREP fgrep; bzgrep string files)
