bash-minimal1
A bash version configured with minimal features
Usage
bash [options] ...
[file]
Overview
bash-minimal is configured using --enable-minimal-config, which produces a shell with minimal features, close to the historical Bourne shell. This means:
- •
-
No alias expansion and the `alias' and `unalias' builtins.
- •
-
No support for the alternate form of the `for' command that behaves like the C language `for' statement.
- •
-
No support for one-dimensional array shell variables.
- •
-
No support for `csh'-like history substitution.
- •
-
No `csh'-like brace expansion ( `b{a,b}c' ==> `bac bbc' ).
- •
-
No support for recognizing `time' as a reserved word and for displaying timing statistics for the pipeline following `time'. This allows pipelines as well as shell builtins and functions to be timed.
- •
-
No support for the `[[' conditional command.
- •
-
No support for a `csh'-like directory stack and the `pushd', `popd', and `dirs' builtins
- •
-
No support for the `((...))' command.
- •
-
No support for the extended pattern matching features.
- •
-
No `help' builtin, which displays help on shell builtins and variables.
- •
-
No command history and the `fc' and `history' builtin commands.
- •
-
No job control features.
- •
-
No special handling of filenames of the form `/dev/tcp/HOST/PORT' and `/dev/udp/HOST/PORT' when used in redirections.
- •
-
No process substitution.
- •
-
No interpretation of a number of backslash-escaped characters in the `$PS1', `$PS2', `$PS3', and `$PS4' prompt strings.
- •
-
No programmable completion facilities.
- •
-
No support for command-line editing and history with the Bash version of the Readline library.
- •
-
No support for a "restricted shell". If this is enabled, Bash, when called as `rbash', enters a restricted mode.
- •
-
No `select' builtin, which allows the generation of simple menus.
