Bash idioms — strict mode, parameter expansion, arrays, trap cleanup, heredocs, and POSIX portability. Auto-load when working with .sh, .bash files, or when the user mentions bash, shell, shellcheck, set -e, or pipefail.
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
# Bash
## Strict mode
```bash
set -euo pipefail
IFS=$'\n\t'
```
- `-e` is suppressed in conditional contexts (`||`, `&&`, `if`, `!`); explicit subshells `(...)` **do** inherit it — use `|| true` to absorb expected failures.
- `-u` treats unset variables as errors; unset arrays trigger it: declare before use (`arr=()`) or guard with `${arr[@]+"${arr[@]}"}` for optional arrays.
- `IFS=$'\n\t'` prevents accidental word-splitting on spaces in `for` loops and command substitution.
## Quoting and tests
- Always `"$var"` — bare `$var` triggers word splitting and glob expansion.
- `'literal'` for fixed strings with no expansion needed.
- Prefer `[[ ]]` over `[ ]`: supports `=~` regex, no word splitting, lexical string comparison.
- `$()` over backticks: nestable, readable, no escaping required.
```bash
if [[ "$filename" =~ \.(sh|bash)$ ]]; then
shellcheck "$filename"
fi
```
## Parameter expansion
- `${var:-default}` — substitute default if unset or empty.
- `${var:?error msg}` — abort with message if unset; pairs well with `set -u`.
- `${var%suffix}` — strip shortest suffix match (e.g. strip extension).
- `${var//pattern/repl}` — replace all occurrences in-place.

How to install
mdr add lugassawan/swe-workbench/language-bash@sha256:932a1297a598f495The line at the top of this page pins the label git:20260828.71a6399, 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.
