zgrep

Zgrep is a command line tool used for searching and manipulating text files compressed with gzip compression. It allows you to search for specific patterns or strings within compressed files without having to decompress them first. Here are some key points about zgrep:

1. Zgrep works with gzip compressed files and can search for patterns in these files directly.
2. It is similar to regular grep, but with the ability to work on compressed files.
3. By default, zgrep prints matching lines to the standard output.
4. It supports various search options like case-insensitive searches, multiple patterns, and regular expressions.
5. You can use zgrep to search for patterns across multiple compressed files at once.
6. Zgrep automatically decompresses the compressed input files on-the-fly while searching for the patterns.
7. The tool can handle files compressed with other compression formats like .Z and .bz2 using appropriate options.
8. Zgrep offers additional options for controlling the output format, such as printing the matching filenames alongside the matched lines.
9. It provides options to limit or expand the search to specific line numbers or byte offsets within the compressed files.
10. Zgrep is a powerful tool for efficiently searching and analyzing text within compressed files, saving time and storage space.
