+# The `gunzip` command
+
+The `gunzip` command is an antonym command of [`gzip` command](015-the-gzip-command.md). In other words, it decompresses files deflated by the `gzip` command.
+
+`gunzip` takes a list of files on its command line and replaces each file whose name ends with _.gz_, _-gz_, _.z_, _-z_, or *\_z* (ignoring case) and which begins with the correct magic number with an uncompressed file without the original extension. `gunzip` also recognizes the special extensions *.tgz* and *.taz* as shorthands for *.tar.gz* and  *.tar.Z*  respectively.
+
+### Examples:
+
+1. Uncompress a file
+
+```
+gunzip filename.gz
+```
+
+2. Recursively uncompress content inside a directory, that match extension (suffix) compressed formats accepted by `gunzip`:
+
+```
+gunzip -r directory_name/
+```
+
+3. Uncompress all files in the current/working directory whose suffix match *.tgz*:
+
+```
+gunzip -S .tgz *
+```
+
+4. List compressed and uncompressed sizes, compression ratio and uncompressed name of input compressed file/s:
+
+```
+gunzip -l file_1 file_2
+```
+
+### Syntax:
+
+```
+gunzip [ -acfhklLnNrtvV ] [-S suffix] [ name ...  ]
+```

+[This video](https://www.youtube.com/watch?v=OBtG8zfVwuI) shows how to compress and decompress in a Unix shell. It uses `gunzip` as decompression command.
