The Tin Summer

If you do a significant amount of programming, you'll probably end up with build artifacts scattered about. sn is a tool to help you find those artifacts.

sn is also a replacement for du. It has far nicer output, saner commands and defaults, and it even runs faster on big directories thanks to multithreading.

Installation

Binary install

The easiest way to install is to download a binary from the releases page.

Cargo

If your platform doesn't have binaries, get cargo. Then:

 $ cargo install tin-summer

Make sure you are on nightly; otherwise

 $ rustup run nightly cargo install tin-summer

Shell completions

After setting BASH_COMPLETIONS_DIR or FISH_COMPLETIONS_DIR, you can install the bash or fish features like so:

 $ cargo install --features fish tin-summer

Note that this might need to be run as root, depending on your setup.

Use

To list directory and file sizes for the current directory:

$ sn all -f

To get a list of directory sizes concurrently, excluding version control:

 $ sn p --exclude '\.git|\.pijul|_darcs|\.hg'

To get a sorted list of the 12 biggest directories in $DIR:

 $ sn sort $DIR -n12

To search current directory for directories with build artifacts:

 $ sn ar

To look for artifacts or directories containing artifacts that occupy more than 200MB of disk space:

 $ sn ar -t200M

Accessibility

To turn off colorized output:

export CLICOLOR=0

Comparison

Reasons to use du

• Reads disk usage, not file sizes
• Optionally dereferences symlinks
• Slightly faster on small directories
• Well-supported

Reasons to use sn

• Faster on large directories
• Uses regex for exclusions, making it dramatically faster than du when used with the --exclude flag.
• Defaults to human-readable output
• Colorized output
• Nicer help via clap
• Provides Sorted output
• Finds build artifacts
• Reads file sizes, not disk usage
• Extensible in Rust
• Benefits from upstream improvements in Rust ecosystem

Heuristic for build artifacts

Currently, sn looks for files that either have an extension associated with build artifacts, or executable files that are ignored by version control. It also looks for "build directories", like .stack-work, elm-stuff, etc. and it considers all their contents to be build artifacts.

Languages Supported

The following is a list of languages sn artifacts has been tested with. The intent is to support basically anything, so feel free to open a PR or start an issue.

• Haskell (incl. GHCJS)
• rust
• julia
• python
• Elm
• nim
• Vimscript
• Idris
• FORTRAN
• C
