# ouch
`ouch` is the Obvious Unified Compression (and decompression) Helper.
## How does it work?
`ouch` infers commands from the extensions of its command-line options.
```
ouch 0.1.0
ouch is a unified compression & decompression utility
USAGE:
ouch [OPTIONS] --input <input>...
FLAGS:
-h, --help Displays this message and exits
-V, --version Prints version information
OPTIONS:
-i, --input <input>... Input files (TODO description)
-o, --output <output> Output file (TODO description)
```
### Examples
#### Decompressing a bunch of files
```bash
$ ouch -i file{1..5}.zip
info: attempting to decompress input files into single_folder
info: done!
```
When no output file is supplied, `ouch` infers that it must decompress all of its input files. This will error if any of the input files are not decompressable.
#### Decompressing a bunch of files into a folder
```bash
$ ouch -i file{1..5}.tar.gz -o some-folder
info: attempting to decompress input files into single_folder
info: done!
```
When the output file is not a compressed file, `ouch` will check if all input files are decompressable and infer that it must decompress them into the output file.
#### Compressing files
```bash
$ ouch -i file{1..20} -o archive.tar
info: trying to compress input files into 'archive.tar'
info: done!
```
### Error scenarios
#### No clear decompression algorithm
```bash
$ ouch -i some-file -o some-folder
error: file 'some-file' is not decompressable.
```
`ouch` might (TODO!) be able to sniff a file's compression format if it isn't supplied in the future, but that is not currently implemented.
