# 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}}"`
