I guess what you mean is starting that command from within a Ciao program. Have a look at the 'system' library in the Ciao manual. The system/1, system/2, popen/3, exec/3 and exec/4 predicates do what you want (with different levels of sophistication).
If what you mean is starting it from the Ciao development environment (i.e., within emacs, extended with the ciao 'mode'), then simply start a shell (M-x shell) and type the command within the shell.
Hope this helps.

The 'system' library includes several predicates to do this. As an example,
% Load the module into the toplevel:
?- use_module(library(system)). Note: module system already in executable, just made visible
yes ?- system('ls -l'). %% Note it _has_ to be an atom total 2292 drwxr-xr-x 2 boris profesor 4096 Feb 19 19:41 CVS -rw-r--r-- 1 boris profesor 996 Feb 14 17:06 Makefile [...lots of junk...]
yes %% If you have to use an string, you must convert it to an atom first ?- atom_codes(Command, "ls -l"), system(Command).atom_codes(Command, "ls -l"), system(Command). total 2292 drwxr-xr-x 2 boris profesor 4096 Feb 19 19:41 CVS -rw-r--r-- 1 boris profesor 996 Feb 14 17:06 Makefile [...again the same junk...]
Command = 'ls -l' ?
Hope this helps.
Cheeers,
MCL
