# 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 don’t 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
