The current script says it is based on a Lintian scripts check with copyright ancestry from Richard Braakman, Josip Rodin, and Julian Gilbey. ### Adoption history checkbashisms entered devscripts as a new script in the August 2003 changelog. Because devscripts is a standard Debian developer utility package, the command spread first through Debian and Ubuntu workflows, then through repackaging in Homebrew, Alpine, Nix, Arch, and openSUSE as recorded in the batch input. ### How it is used Users run `checkbashisms script ...` to warn about constructs not required by POSIX, with options for stricter POSIX checking, force-checking, lint-style editor output, extra context, and early failure. ### Why package nerds care checkbashisms is package-nerd folklore because it encodes Debian Policy and POSIX shell portability expectations into a tiny linter, catching scripts that accidentally require bash when packaged as /bin/sh-compatible. ### Timeline - 1997: devscripts split off from debmake. - 1998: Lintian-era scripts checks provide part of checkbashisms' ancestry. - 2003: checkbashisms added to devscripts. - 2018: Debian devscripts repository created on Salsa. - 2026: devscripts 2.26.9 source published in Debian unstable. ### Related projects - devscripts is the Debian utility collection that ships checkbashisms. - Lintian is the source of the original check logic described in the script and manpage. - dash, POSIX sh, Debian Policy, and bash are the compatibility context for the command. ### Sources - - - - - ## Security Notes generalized runtime or code generation signal. - **Geiger risk:** yellow / medium - generalized runtime or code generation signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** checkbashisms - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Nix - checkbashisms: normalized package name match | nixpkgs package indexes: pkgs/by-name/ch/checkbashisms/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - apk - checkbashisms - 2.26.5-r1: normalized package name match | Alpine Linux edge package indexes: checkbashisms from https://dl-cdn.alpinelinux.org/alpine/edge/main/x86_64/APKINDEX.tar.gz | Debian developer scripts (checkbashisms) | https://tracker.debian.org/pkg/devscripts - pacman - checkbashisms - 2.26.9-1: normalized package name match | Arch Linux sync databases: checkbashisms from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | Debian script that checks for bashisms | https://tracker.debian.org/pkg/devscripts - zypper - checkbashisms - 2.26.9-1.1: normalized package name match | openSUSE Tumbleweed package metadata: checkbashisms from https://download.opensuse.org/tumbleweed/repo/oss/repodata/be8d3611d25469107f32075a1697e69ec57a2b850b42348a658cc671ad5ec2b50760d02c3e59524d50da9a11d5be799bdaffba2e166e8ca8858512e3c0bd665d-primary.xml.zst | Tool for checking /bin/sh scripts for possible bashisms | https://salsa.debian.org/debian/devscripts ## Related links - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [bashate](https://www.automicvault.com/pkg/brew/bashate/) - Shares av.db curated category or tags: cli, developer-tools, linting, shell. - [shellcheck](https://www.automicvault.com/pkg/brew/shellcheck/) - Shares av.db curated category or tags: cli, developer-tools, linting, shell. - [shellspec](https://www.automicvault.com/pkg/brew/shellspec/) - Shares av.db curated category or tags: cli, developer-tools, posix, shell. - [shfmt](https://www.automicvault.com/pkg/brew/shfmt/) - Shares av.db curated category or tags: cli, developer-tools, posix, shell. - [actionlint](https://www.automicvault.com/pkg/brew/actionlint/) - Shares av.db curated category or tags: cli, developer-tools, linting. - [aliae](https://www.automicvault.com/pkg/brew/aliae/) - Shares av.db curated category or tags: cli, developer-tools, shell. - [bar](https://www.automicvault.com/pkg/brew/bar/) - Shares av.db curated category or tags: cli, developer-tools, shell. - [bpmnlint](https://www.automicvault.com/pkg/brew/bpmnlint/) - Shares av.db curated category or tags: cli, developer-tools, linting. - [reprepro](https://www.automicvault.com/pkg/brew/reprepro/) - Local package facts share a topical domain.
