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 --extended-regexp --ignore-case "{{search_pattern}}" {{path/to/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 --with-filename --line-number "{{search_pattern}}" {{path/to/file}}

• Search for lines matching a pattern, printing only the matched text:

bzgrep --only-matching "{{search_pattern}}" {{path/to/file}}

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

bzgrep --recursive "{{search_pattern}}" {{path/to/tar/file}}

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

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