Find patterns in `bzip2` compressed files using `grep`.

Search for a pattern within a compressed file
bzgrep "{{search_pattern}}" {{path/to/file}}
Recursively search files in a bzip2 compressed `.tar` archive for a pattern
bzgrep {{-r|--recursive}} "{{search_pattern}}" {{path/to/tar_file}}
Print 3 lines of Context around, Before, or After each match
bzgrep {{-context|--before-context|--after-context}} 3 "{{search_pattern}}" {{path/to/file}}
Print file name and line number for each match
bzgrep {{-H|--with-filename}} {{-n|--line-number}} "{{search_pattern}}" {{path/to/file}}
Search for lines matching a pattern, printing only the matched text
bzgrep {{-o|--only-matching}} "{{search_pattern}}" {{path/to/file}}
Search `stdin` for lines that do not match a pattern
cat {{path/to/bz_compressed_file}} | bzgrep {{-v|--invert-match}} "{{search_pattern}}"
Use extended `regex` (supports `?`, `+`, `{}`, `()`, and `|`), in case-insensitive mode
bzgrep {{-E|--extended-regexp}} {{-i|--ignore-case}} "{{search_pattern}}" {{path/to/file}}

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 neces‐
       sary  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)
