# 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}}"`
