The library function, ask, parameterized by a shell descriptor, such as bash,
spawns a process that interacts with that shell by feeding it a list of
commands, and returns a transcript of the interaction.
Here is a self-contained command line application providing a limited replacement
for the ls command.
<lang Ursala>#import std
#import cli
#executable ('parameterized','')
myls = <.file$[contents: --<''>]>@hm+ (ask bash)/0+ -[ls --color=no]-!</lang>
