27 3. Great error message feedback.
28 4. No runtime dependencies required (for _Linux x86_64_).
29 5. Accessibility mode ([see more](https://github.com/ouch-org/ouch/wiki/Accessibility)).
30 6. Shell completions and man pages.
34 Ouch has three main subcommands:
36 - `ouch decompress` (alias `d`)
37 - `ouch compress` (alias `c`)
38 - `ouch list` (alias `l` or `ls`)
40 To see `help` for a specific command:
44 ouch <COMMAND> --help # equivalent
49 Use the `decompress` subcommand, `ouch` will detect the extensions automatically.
54 # Decompress multiple files
55 ouch decompress a.zip b.tar.gz c.tar
58 The `-d/--dir` flag can be used to redirect decompression results to another directory.
61 # Decompress 'summer_vacation.zip' inside of new folder 'pictures'
62 ouch decompress summer_vacation.zip --dir pictures
67 Pass input files to the `compress` subcommand, add the **output file** at the end.
70 # Compress two files into `archive.zip`
71 ouch compress one.txt two.txt archive.zip
73 # Compress file.txt using .lz4 and .zst
74 ouch compress file.txt file.txt.lz4.zst
77 `ouch` detects the extensions of the **output file** to decide what formats to use.
84 # Example with tree formatting
85 ouch list source-code.zip --tree
114 | Format | `.tar` | `.zip` | `.gz` | `.xz`, `.lzma` | `.bz`, `.bz2` | `.lz4` | `.sz` | `.zst` |
115 |:---------:|:---:|:---:|:---:|:---:|:---:|:---:|:---:|:---:|
116 | Supported | ✓ | ✓¹ | ✓² | ✓ | ✓ | ✓ | ✓² | ✓ |
118 ✓: Supports compression and decompression.
120 ✓¹: Due to limitations of `.zip`, it doesn't support streaming (de)compression.
122 ✓²: Supported, and compression runs in parallel.
124 `tar` aliases are also supported: `tgz`, `tbz`, `tbz2`, `tlz4`, `txz`, `tlzma`, `tsz`, `tzst`.
126 Formats can be chained:
130 - `.tar.gz.gz.gz.zst.xz.bz.lz4`
132 If the filename has no extensions, `Ouch` will try to infer the format by the [file signature](https://en.wikipedia.org/wiki/List_of_file_signatures).

146 ## On Windows via Scoop
158 ## Download the latest release bundle
160 Check the [releases page](https://github.com/ouch-org/ouch/releases).
162 ## Compiling from source code
164 Check the [wiki guide on compiling](https://github.com/ouch-org/ouch/wiki/Compiling-and-installing-from-source-code).
168 If you installed `ouch` using the download script, you will need no dependencies (static MUSL binary).
170 Otherwise, you'll need these libraries installed on your system:
172 * [liblzma](https://www.7-zip.org/sdk.html)
173 * [libbz2](https://www.sourceware.org/bzip2/)
174 * [libz](https://www.zlib.net/)
176 These are available on all mainstream _Linux_ distributions and on _macOS_.
180 Benchmark results are available [here](benchmarks/results.md).
181 Performance of compressing and decompressing
182 [Rust](https://github.com/rust-lang/rust) source code are measured and compared with
183 [Hyperfine](https://github.com/sharkdp/hyperfine).
184 The values presented are the average (wall clock) elapsed time.
186 Note: `ouch` focuses heavily on usage ergonomics and nice error messages, but
187 we plan on doing some optimization in the future.
