Modern CLI Tools

Use faster, ergonomic command-line tools installed on this system. Pick the tool by target, not habit. Habit is how grep -R survives.

Quick Reference

• Search code structure — ast-grep / sg (vs grep): AST-aware patterns, language constructs, safer refactor candidate search.
• Search text — rg (vs grep): fast literal/regex search, respects .gitignore.
• Find files — fd (vs find): simpler syntax, ignores .git.
• View files — bat (vs cat): syntax highlighting, line numbers.
• List files — eza (vs ls): icons, git status, tree view.
• Replace text — sd (vs sed): intuitive regex, preview mode.
• Disk usage — dust (vs du): visual tree, sorted by size.
• Processes — procs (vs ps): tree view, sortable columns.
• Diff files — delta (vs diff): syntax highlighting, side-by-side.
