软件包摘要

POSIX-compliant descendant of NetBSD's ash (the Almquist SHell)

命令和别名

  • dash

历史

项目历史与用法

dash is a small POSIX shell descended from the Almquist shell lineage. In package-manager culture it is the fast, minimal `/bin/sh` candidate: less interactive shell comfort than Bash, but a tighter target for scripts that claim POSIX portability.

项目历史

dash descends from NetBSD's ash, the Almquist shell, and is maintained as a lightweight command interpreter for POSIX shell scripts. Its manual documents a shell focused on command execution, scripts, redirection, expansions, and built-ins rather than interactive user features.

The project became especially visible through Debian and Ubuntu system-shell work, where dash's speed and small size made it a candidate for `/bin/sh`. That history turned a modest shell implementation into an important compatibility test for shell scripts.

采用历史

Debian's dash-as-bin-sh effort made dash part of everyday Linux packaging culture: maintainer scripts and `/bin/sh` scripts needed to stop relying on Bash-only behavior. The result was not just adoption of a shell, but pressure toward cleaner POSIX shell scripting across packages.

Homebrew packages it as `dash-shell` to avoid name ambiguity while still exposing the `dash` executable. Other Unix-like distributions package it simply as `dash`, often as a system scripting shell rather than an interactive login shell.

使用方式

Typical use is running POSIX shell scripts directly with `dash` or using it as `/bin/sh` on systems configured that way. It normally has no package-specific user config or credential store; shell startup behavior and scripts are governed by POSIX shell conventions and the system configuration.

为什么软件包爱好者会关心

dash matters because it catches accidental Bashisms. If a package maintainer script works under dash, it is more likely to be genuinely portable `/bin/sh`; if it breaks, the package has probably encoded an undeclared Bash dependency.

时间线

  • Almquist shell era: ash provided the small POSIX shell lineage that dash descends from.
  • Debian dash-as-bin-sh era: dash became a prominent `/bin/sh` implementation for package scripts.
  • Present: dash is maintained in the kernel.org source tree and packaged across Unix-like systems.

Related projects

  • dash is related to ash, NetBSD sh, BusyBox ash, Bash in POSIX mode, and the broader family of `/bin/sh` implementations used by Unix package scripts.
