shell-scripting skillA
shell-scripting is agent-read markdown (skill) from iuliandita/skills: Write and debug Bash, Zsh, POSIX sh, and Fish scripts, commands, quoting, dotfiles, and shell completions..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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 …

mdr add iuliandita/skills/shell-scripting@git:20260920.ac01853mdr add iuliandita/skills/shell-scripting@sha256:c6374e034bcda6d7Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
