A curated list of command-line utilities written in Rust

A curated list of command-line utilities written in Rust

Note: I have moved this list to a proper repository. I'll leave this gist up, but it won't be updated. To submit an idea, open a PR on the repo.

Note that I have not tried all of these personally, and cannot and do not vouch for all of the tools listed here. In most cases, the descriptions here are copied directly from their code repos. Some may have been abandoned. Investigate before installing/using.

The ones I use regularly include: bat, dust, fd, fend, hyperfine, miniserve, ripgrep, just, cargo-audit and cargo-wipe.

  • atuin: "Magical shell history"
  • bandwhich: Terminal bandwidth utilization tool
/* So how does this work?
I'm using ANSI escape sequences to control the behavior of the terminal while
cat is outputting the text. I deliberately place these control sequences inside
comments so the C++ compiler doesn't try to treat them as code.*/
//
/*The commands in the fake code comment move the cursor to the left edge and
clear out the line, allowing the fake code to take the place of the real code.
And this explanation uses similar commands to wipe itself out too. */

Forgot to sign-off commits?

No problem,

run

git filter-branch --msg-filter "cat - && echo && echo 'Signed-off-by: Your Name <Your.Name@example.com>'" HEAD~2..HEAD

To sign-off the last two commits.

Then force to push them to the remote repo with the -f option:
