# zegrep
|
|
|
|
> Find extended regular expression patterns in compressed files using `egrep`.
|
|
> More information: <https://www.unix.com/man-page/freebsd/1/zegrep/>.
|
|
|
|
- Search for extended regular expressions (supporting `?`, `+`, `{}`, `()` and `|`) in a compressed file (case-sensitive):
|
|
|
|
`zegrep "{{search_pattern}}" {{path/to/file}}`
|
|
|
|
- Search for extended regular expressions (supporting `?`, `+`, `{}`, `()` and `|`) in a compressed file (case-insensitive):
|
|
|
|
`zegrep {{[-i|--ignore-case]}} "{{search_pattern}}" {{path/to/file}}`
|
|
|
|
- Search for lines that do not match a pattern:
|
|
|
|
`zegrep {{[-v|--invert-match]}} "{{search_pattern}}" {{path/to/file}}`
|
|
|
|
- Print file name and line number for each match:
|
|
|
|
`zegrep {{[-H|--with-filename]}} {{[-n|--line-number]}} "{{search_pattern}}" {{path/to/file}}`
|
|
|
|
- Search for lines matching a pattern, printing only the matched text:
|
|
|
|
`zegrep {{[-o|--only-matching]}} "{{search_pattern}}" {{path/to/file}}`
|
|
|
|
- Recursively search files in a compressed file for a pattern:
|
|
|
|
`zegrep {{[-r|--recursive]}} "{{search_pattern}}" {{path/to/file}}`
|
