NAME
bzgrep, bzfgrep, bzegrep - search possibly bzip2 compressed files for a regular expressionSYNOPSIS
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)
