Bash Portable

Bash Portable is a portable version for Windows of the bash shell. Bash is a command processor that allows the user to type commands which cause actions.

Bash can also read commands from a file, called a script. Like all Unix shells, it supports filename wildcarding, piping, here documents, command substitution, variables and control structures for condition-testing and iteration.

The keywords, syntax and other basic features of the language were all copied from sh. Other features, e.g., history, were copied from csh and ksh. Bash is a POSIX shell but with a number of extensions.
