bzgrep

Find patterns in bzip2 compressed files using grep.

More information.

• 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}"
