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"
