name: bash-use description: Ultra-concise bash command patterns. Use when constructing shell commands or one-liners.

Bash Use Skill

Patterns for interactive bash commands, one-liners, and CLI usage.

---

When to Use

• Constructing shell commands
• Writing one-liners
• Interactive CLI usage
• Command debugging or improvement

---

Quick Reference

Quote paths with spaces:

Copycd "/path with spaces/dir"

Relative paths with rm:

Copyrm -rf ./build  # Not $HOME/...

Chain commands:

Copycmd1 && cmd2 && cmd3  # Stop on failure
cmd1; cmd2; cmd3      # Continue regardless

Command substitution:

Copyresult=$(command)  # Not `command`

Check command exists:

Copycommand -v jq &>/dev/null || echo "not found"

Output redirection:

Copycommand 2>&1        # Stderr to stdout
command &>/dev/null # Suppress all

Process substitution:

Copydiff <(cmd1) <(cmd2)

Full Guidelines

Read: ~/.claude/skills/code-implement/resources/loqui/languages/bash/reference/commands.md

Use Read tool to access (paths outside cwd require direct reads).

Anti-Patterns Checklist

• ✘ Unquoted paths with spaces
• ✘ Absolute paths with rm
• ✘ Using ; when && is needed
• ✘ Backticks instead of $()
