# cachedir
[](https://crates.io/crates/cachedir)
[](https://github.com/jstasiak/cdir/actions?query=workflow%3ACI+branch%3Amaster)
[](https://codecov.io/gh/jstasiak/cachedir)
A Rust library and a CLI tool to help interacting with cache directories and CACHEDIR.TAG files
as defined in [Cache Directory Tagging Specification](https://bford.info/cachedir/).
You can find the [library documentation on docs.rs](https://docs.rs/cachedir/).
To install the CLI tool run `cargo install cachedir`. To see what options are available
run `cachedir --help`. Only one subcommand, `is-tagged`, is implemented right now.
It allows checking if a directory is tagged with `CACHEDIR.TAG` (prints the relevant
information to stderr *and* sets an appropriate exit-code: 0 for true, 1 for false, 2 for an error):
```
~/projects/cachedir% ls -lah target
total 16
drwxr-xr-x@ 6 user staff 192B Dec 10 17:02 ./
drwxr-xr-x 10 user staff 320B Dec 10 17:16 ../

Versions 0.1.0 and 0.1.1 of this crate on [crates.io](https://crates.io) are actually distributions of
[a different, abandonded project by Lilian Anatolie Moraru](https://github.com/lilianmoraru/cachedir).
Credits to Lilian for transferring the name to me.
