Fast CLI Tools

Execute fast CLI commands with smart defaults. These modern replacements are significantly faster and more ergonomic than their traditional counterparts.

Tool Mappings

Traditional	Fast Alternative	Purpose
`ls`	`eza`	List files with git status, icons
`find`	`fd`	Find files by pattern
`grep`	`rg`	Search file contents
`cat`	`bat`	View files with syntax highlighting
`du`	`dust`	Disk usage visualization
`df`	`duf`	Disk free space
`top`	`btop`	System monitor
`cd`	`z` (zoxide)	Smart directory jumping
`diff`	`delta`	Beautiful diffs
`jq`	`jq`/`jless`	JSON processing

Smart Defaults

eza (file listing)

bash

# Basic listing with git status and icons
eza -la --git --icons

# Tree view (2 levels deep)
eza --tree --level=2 --icons

# Show only directories
eza -D --icons

# Sort by modification time (newest first)
eza -la --sort=modified --reverse --icons

# Group directories first
eza -la --group-directories-first --icons

fd (find files)

bash

# Find by pattern (faster than find)
fd "pattern"

# Find specific extension
fd -e py

# Find and execute command on each
fd -e json -x jq .

# Find hidden files too
fd -H "pattern"

# Find only directories
fd -t d "pattern"

# Exclude directories
fd -E node_modules -E .git "pattern"

rg (ripgrep - search contents)

bash

# Search for pattern
rg "pattern"

# Search specific file types
rg -t py "import"

# Show context (3 lines before/after)
rg -C 3 "pattern"

# Case insensitive
rg -i "pattern"

# Fixed string (not regex)
rg -F "exact match"

# Count matches per file
rg -c "pattern"

# Files with matches only
rg -l "pattern"

dust (disk usage)

bash

# Disk usage of current directory
dust

# Limit depth
dust -d 2

# Show hidden files
dust -a

# Reverse order (smallest first)
dust -r

# Only show N items
dust -n 10

# Specific path
dust /path/to/dir

bat (file viewing)

bash

# View file with syntax highlighting
bat file.py

# Show line numbers only
bat -n file.py

# Plain output (no decorations)
bat -p file.py

# Specify language
bat -l json file.txt

# Show non-printable characters
bat -A file.txt

# Multiple files
bat file1.py file2.py

fzf (fuzzy finder)

bash

# Interactive file selection
fd | fzf

# Preview files while selecting
fd | fzf --preview 'bat --color=always {}'

# Multi-select with tab
fd | fzf -m

# Search in file contents
rg "" --files | fzf --preview 'rg --color=always {} {}'

zoxide (smart cd)

bash

# Jump to frecent directory
z project-name

# Interactive selection
zi

# Add current directory to database
z add .

jq / jless (JSON)

bash

# Pretty print JSON
jq . file.json

# Extract field
jq '.key' file.json

# Filter array
jq '.[] | select(.active == true)' file.json

# Interactive JSON exploration
jless file.json

duf (disk free)

bash

# Show disk usage
duf

# Only local filesystems
duf --only local

# Specific path
duf /home

delta (diffs)

bash

# Git diff with delta (configure in gitconfig)
git diff

# Diff two files
delta file1.txt file2.txt

Custom Utilities (dotfiles)

Located in custom_bins/:

Command	Purpose
`utc_date`	Outputs date in DD-MM-YYYY format
`utc_timestamp`	Outputs DD-MM-YYYY_HH-MM-SS
`tmux-clean`	Start tmux with minimal environment
`tsesh`	Tmux session management
`twin`	Tmux window management
`rcopy`/`rpaste`	Remote clipboard (SSH)
`machine-name`	Get machine hostname
`sync-secrets`	Sync secrets with GitHub gist
`clear-claude-code`	Clean up Claude Code sessions
`clear-mac-apps`	Clean up macOS application data

Execution Guidelines

When asked to perform file operations:

•Prefer fast alternatives - Use eza over ls, fd over find, rg over grep
•Use smart defaults - Include --icons for eza, -C 3 for rg context
•Limit output - Use -n 10 or head for long listings
•Combine tools - Pipe fd to fzf for interactive selection

Common Patterns

bash

# Find large files
dust -n 20

# Search and preview
fd -e py | fzf --preview 'bat --color=always {}'

# Recent files
eza -la --sort=modified -r | head -20

# Project overview
eza --tree --level=2 --icons -I 'node_modules|.git|__pycache__|.venv'

# Find TODO comments
rg -t py "TODO|FIXME|XXX" -C 1
