Bash

What this skill does

Writes, debugs, and hardens Bash shell scripts — quoting, arrays, strict mode, traps, argument parsing, and macOS/Linux portability. Use when writing or reviewing any script, one-liner, cron job, deploy script, container entrypoint, or CI step; when a script breaks on spaces in filenames, exits silently, ignores set -e, hangs, or returns the wrong exit code; when quoting, IFS, globs, arrays, heredocs, process substitution, trap, getopts, or mapfile misbehave; when shellcheck flags SC2086 and friends; when unbound variable, bad substitution, command not found, ambiguous redirect, or unexpected end of file show up; when a script works by hand but fails under cron, systemd, sudo, or a CI runner; or when porting between macOS bash 3.2, GNU/Linux, WSL, and POSIX sh. Not for interactive zsh or fish configuration, not for PowerShell, and not for host-level cron, systemd, or permission failures (linux).

Bash is part of the Developer Tools category — developer tools that help your agent write, review, debug, and ship code. You can install it on its own or alongside other developer tools skills from the OpenClaw catalog.

How to install Bash

The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:

1. Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
2. Open the in-app Skills panel.
3. Search for bash and click Install.
4. The skill activates automatically when an incoming message matches its description.

Install from the command line

If you already run the OpenClaw CLI, add Bash with a single command:

openclaw skills add bash

This pulls bash from ClawHub and installs it into ~/.openclaw/skills/bash/. Restart the OpenClaw gateway afterwards so the new skill is discovered.

How to use Bash

Once installed, Bash activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.

Manual install (advanced)

If you prefer manual installation:

1. Click the Download .zip button above to grab bash-1.0.6.zip directly from our S3 mirror.
2. Unzip into ~/.openclaw/skills/bash/ (create the directory if it does not exist).
3. Restart OpenClaw Easy (or the OpenClaw CLI gateway) so the new skill is discovered.
