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:

cd "/path with spaces/dir"

rm requires relative paths — absolute paths through $HOME, /, etc. are blocked:

rm -rf ./build       # relative: allowed
rm -rf $HOME/build   # absolute: blocked

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)
