fcat, short for fastcat, is a
cat implementation in Rust using Linux's
With that little trick, it's more than three times as fast as the system
cat in our benchmarks.
Read the announcement here.
cat myfile | pv -r > /dev/null [1.90GiB/s]
fcat myfile | pv -r > /dev/null [5.90GiB/s]
Note: Only works on Linux.
(But you can send me a pull request for other operating systems.)
cargo install fcat
fcat file1 file2 file3
- Be the fastest cat in town.
- Be a drop-in replacement for (POSIX) cat.
- Provide any additional functionality other than what
If you're looking for a more beautiful cat, check out bat.
If you run
fcat /dev/zero >> myfile, it will fail with exit code
EINVAL because, according to the splice manpage: "The target file is opened in append mode."
- You probably won't ever need this, but it's a fun little experiment.
Still, I wonder why this is not part of e.g. GNU cat...
- What I like the most about the project is the logo.
