BZGREP(1) General Commands Manual BZGREP(1)

# [NAME](#NAME)

bzgrep, bzfgrep, bzegrep - search possibly bzip2 compressed files for a regular expression

# [SYNOPSIS](#SYNOPSIS)

**bzgrep** \[ grep\_options ] **\[ -e ] pattern** *filename*...  
**bzegrep** \[ egrep\_options ] **\[ -e ] pattern** *filename*...  
**bzfgrep** \[ fgrep\_options ] **\[ -e ] pattern** *filename*...

# [DESCRIPTION](#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)
