Install Cargo, the package manager for the Rust programming language. Then run:
sh
$ cargo install len
```sh $ cat /usr/share/dict/words | len
2.4 MiB ```
len
will print its output in human-readable format if the output is a terminal,
or a plain number otherwise, in which case it is the same as using wc -c
.
