dfish (DarkF's Interpreting SHell)

A minimal POSIX-like shell written in Haskell.

Example usage:

./dfish
$ echo hi
hi
$ echo there > foo.txt
$ echo hi | cat - foo.txt
hi
there
$ quit

It supports running commands with arguments, command piping (|) and file redirection (< to pipe to a command's input, > to pipe a command's output to a file).

Arguments and operators must be separated with a space.

You may run the shell with the -c argument and supply a command after it to immediately execute the command and return, for example: ./dfish -c "echo hi".
