# zipping and unzipping files
gzip, gunzip, tar
## gzip
gzip (GNU zip) - used to compress individual files(single files only)
**Note: replaces original file with zipped file**
Usage ->
```sh
gzip [filename]
```
## gunzip
By default it replaces the compressed file with decompressed file
```shell
gunzip [filename]
```
### By using \`-k\` we can keep the original compressed file too
```
gunzip -k [filename]
```
