Oxidize your shell

5+1 modern CLI tools for Ye Olde rusty geekos

Brace yourself

We are going to replace

• cat
• find
• grep
• ps
• time
• PS1

Why ? I like my old tools!

... and they work flawlessly

• A pillar of free software: diversity, richness, freedom of choice... The Bazaar!
• New users use them on other platforms, maybe you want to know what those foolish young hipsters mess around with
• Totally optional, use at your own pace. Nothing disappears installing them
• Good OSS projects, small enough to start contributing in a new programming language (also because they may lack features that unix veterans can bring in )
• Why not ? Trying something new won't hurt

And of course...

... because there's a cute mascot like Ferris the crab

The tools 1/2

1. bat an alternative to cat , with syntax highlighting and git integration. Shows non-printable characters
2. procs a modern replacement for ps: colored output, integrate filtering and paging
3. fd a simple, fast and user-friendly alternative to find. Smart case, colored output, .gitignore integration, parallel command execution

The tools 2/2

4. ripgrep a grep alternative specialized in code search. Fast, unicode+git aware and with replacement support
5. hyperfine a command-line benchmarking tool with many features: analysis across multiple runs, realtime feedback, warmup runs, statistical outlier detection

Bonus mention

Starship

The minimal, blazing-fast, and infinitely customizable prompt for any shell!

How they can be useful ?

• A richer and pleasant CLI experience can improve day to day productivity
• Green field for innovation: no legacy constraints, no limit to try out new ideas
• Learning from well written Rust source code
• Packaged in OpenSUSE (check out how they are packaged on OBS)
