# zgrep
> Grep text patterns from files within compressed file (equivalent to `grep -Z`).
> More information: <https://manned.org/zgrep>.
- Grep a pattern in a compressed file (case-sensitive):
`zgrep {{pattern}} {{path/to/compressed/file}}`
- Grep a pattern in a compressed file (case-insensitive):
`zgrep -i {{pattern}} {{path/to/compressed/file}}`
- Output count of lines containing matched pattern in a compressed file:
`zgrep -c {{pattern}} {{path/to/compressed/file}}`
- Display the lines which dont have the pattern present (Invert the search function):
`zgrep -v {{pattern}} {{path/to/compressed/file}}`
- Grep a compressed file for multiple patterns:
`zgrep -e "{{pattern_1}}" -e "{{pattern_2}}" {{path/to/compressed/file}}`
- Use extended regular expressions (supporting `?`, `+`, `{}`, `()` and `|`):
`zgrep -E {{regular_expression}} {{path/to/file}}`
- Print 3 lines of [C]ontext around, [B]efore, or [A]fter each match:
`zgrep -{{C|B|A}} {{3}} {{pattern}} {{path/to/compressed/file}}`
