bzgrep

Find patterns in bzip2 compressed files using grep. More information: https://manned.org/bzgrep.

• Search for a pattern within a compressed file:

bzgrep "{{search_pattern}}" {{path/to/file}}

• Use extended regular expressions (supports ?, +, {}, () and |), in case-insensitive mode:

bzgrep {{[-E|--extended-regexp]}} {{[-i|--ignore-case]}} "{{search_pattern}}" {{path/to/file}}

• Print 3 lines of [C]ontext around, [B]efore, or [A]fter 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}}

• Recursively search files in a bzip2 compressed tar archive for a pattern:

bzgrep {{[-r|--recursive]}} "{{search_pattern}}" {{path/to/tar/file}}

• Search stdin for lines that do not match a pattern:

cat {{/path/to/bz/compressed/file}} | bzgrep {{[-v|--invert-match]}} "{{search_pattern}}"
