Usage:

zzgrep [ option ... ] [ - ] regex file-or-dir ...

zzgrep [ option ... ] regex

Reads STDIN and prints all lines which contain matches of the regex.

Options:

File Selection:

--dont-sort-directory-members

By default directory members are sorted lexicographically in order to achieve deterministic results.

--look-into glob

Look into compressed and archive contents if "format:path" matches the glob. The default is to look into any recognised archive or compressed contents.
Supported archive formats in this runtime configuration are:
${archive.formats}
Supported compression formats in this runtime configuration are:
${compression.formats}

--exclude regex

--include regex

Excludes files and archive entries from the search iff the file's / archive entry's path matches the regex.

Any number of --exclude and --include options can be given, and later take precedence over the earlier.

The default is that all files and archive entries are included; thus you would always begin with a --exclude option.

--zip

--zz

--nested-zip

--gzip

Deprecated - Use --look-into instead.

-i
