Which shell? Normally the programming language does not specify existence of any shells or others environmental tasks. What happens if the program is run as an [[OS]] driver, a system service, or without any [[OS]] at all on the bare board? Otherwise, how does this task differ from [[Execute a System Command]]? Does spawning a shell qualify? --[[User:Dmitry-kazakov|Dmitry-kazakov]] 13:15, 26 August 2008 (UTC) |

:I guess we could restrict it to mean systems that have command line shells such as bash/tcsh/... on Unix systems, cmd.exe on Windows, or ''[http://www.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html posix-like]'' shells. Maybe we should state what shell the command line is compatible with? --[[User:Paddy3118|Paddy3118]] 13:55, 26 August 2008 (UTC) |

The examples on the page seem to indicate that the task is running a line of the programming language ''from'' a shell; and not doing anything of the shell from the programming language. I am not sure exactly what you are allowed to use; because the OCaml example just echoes a string and pipes it into the ocaml program. You can do that with any language with an interpreter that reads from standard input, so it seems kind of trivial. --[[User:Spoon!|Spoon!]] 19:25, 26 August 2008 (UTC) |
