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:
cd "/path with spaces/dir"
Relative paths with rm:
rm -rf ./build # Not $HOME/...
Chain commands:
cmd1 && cmd2 && cmd3 # Stop on failure
cmd1; cmd2; cmd3 # Continue regardless
Command substitution:
result=$(command) # Not `command`
Check command exists:
command -v jq &>/dev/null || echo "not found"
Output redirection:
command 2>&1 # Stderr to stdout
command &>/dev/null # Suppress all
Process substitution:
diff <(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).
