Mastering Linux CLI in 2026: Advanced Tips

If you are still using `ls` and `cat` in 2026, you are working too hard. The Rust rewrite revolution has given us better, faster tools.

Modern Replacements

• Replace `ls` with `eza`

  It has colors, icons, and git integration out of the box.

• Replace `cat` with `bat`

  Syntax highlighting and line numbers for every file.

• Replace `grep` with `rg` (ripgrep)

  It's orders of magnitude faster and respects your .gitignore.

AI in the Terminal
