Bash, Zsh, POSIX sh, Fish scripts, one-liners, dotfiles, completions. Use for quoting or globbing bugs, shellcheck warnings, porting between shells.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Shell Scripting and Configuration Write commands, scripts, dotfiles, and completions for their actual shell. Detect the target before writing code, then load the smallest relevant reference instead of borrowing syntax from a similar shell. **Version-specific behavior**: read the matching shell reference before relying on release-specific behavior. ## When to use - Writing shell commands, scripts, or one-liners - Configuring dotfiles (`.zshrc`, `.bashrc`, `.profile`, `config.fish`) - Writing completions, shell functions, or aliases - Porting scripts between shells or debugging quoting, globbing, array, or expansion behavior - Choosing a target shell for a new script or interactive command ## When NOT to use - Remote FreeBSD/OPNsense/pfSense commands; use **opnsense-pfsense** - Ansible shell/command modules; use **ansible** - CI/CD pipeline design or runner constraints; use **ci-cd** - General Linux administration that is not a shell-syntax task; do the domain task directly ## AI Self-Check - [ ] Shebang matches the detected target shell, not an assumed Bash default - [ ] Error handling matches the declared shell; expected nonzero statuses are handled deliberately …

How to install
mdr add iuliandita/skills/shell-scripting@sha256:aa214a8139cfcff6The line at the top of this page pins the label git:20261105.aa96fb6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
