# gzip

> Compress/uncompress files with `gzip` compression (LZ77).
> More information: <https://www.gnu.org/software/gzip/manual/gzip.html>.

- Compress a file, replacing it with a `gzip` archive:

`gzip {{path/to/file}}`

- Decompress a file, replacing it with the original uncompressed version:

`gzip {{[-d|--decompress]}} {{path/to/file.gz}}`

- Compress a file, keeping the original file:

`gzip {{[-k|--keep]}} {{path/to/file}}`

- Compress a file, specifying the output filename:

`gzip {{[-c|--stdout]}} {{path/to/file}} > {{path/to/compressed_file.gz}}`

- Decompress a `gzip` archive specifying the output filename:

`gzip {{[-c|--stdout]}} {{[-d|--decompress]}} {{path/to/file.gz}} > {{path/to/uncompressed_file}}`

- Specify the compression level. 1 is the fastest (low compression), 9 is the slowest (high compression), 6 is the default:

`gzip -{{1..9}} {{[-c|--stdout]}} {{path/to/file}} > {{path/to/compressed_file.gz}}`

- Display the name and reduction percentage for each file compressed or decompressed:

`gzip {{[-v|--verbose]}} {{[-d|--decompress]}} {{path/to/file.gz}}`
