Modern CLI Tools
Use faster, ergonomic command-line tools installed on this system.
Quick Reference
| Task | Modern | Traditional | Why Modern |
|---|---|---|---|
| Search text | rg | grep | 10-100x faster, respects .gitignore |
| Find files | fd | find | Simpler syntax, ignores .git |
| View files | bat | cat | Syntax highlighting, line numbers |
| List files | eza | ls | Icons, git status, tree view |
| Replace text | sd | sed | Intuitive regex, preview mode |
| Disk usage | dust | du | Visual tree, sorted by size |
| Processes | procs | ps | Tree view, sortable columns |
| Diff files | delta | diff | Syntax highlighting, side-by-side |
Examples
# Search: rg instead of grep
rg "TODO" --type go # Search Go files
rg -A 3 "error" # 3 lines after match
rg -l "import" # List files only
# Find: fd instead of find
fd "\.go$" # Find Go files
fd -e json src/ # By extension in src/
fd -x wc -l {} # Execute on matches
# View: bat instead of cat
bat main.go # With syntax highlighting
bat -n file.py # Line numbers only
# List: eza instead of ls
eza -la --git # Long format with git status
eza --tree -L 2 # Tree view, 2 levels
# Replace: sd instead of sed
sd "old" "new" file.txt # Simple replacement
sd -p "pattern" "new" # Preview changes first
# Disk: dust instead of du
dust -d 2 # 2 levels deep
# Processes: procs instead of ps
procs --tree # Process tree
