 chmod(+File, +Spec) is det
Set the mode of the target file. Spec is one of +Mode, -Mode or a plain Mode, which adds new permissions, revokes permissions or sets the exact permissions. Mode itself is an integer, a POSIX mode name or a list of POSIX mode names. Defines names are suid, sgid, svtx and all names defined by the regular expression [ugo]*[rwx]*. Specifying none of "ugo" is the same as specifying all of them. For example, to make a file executable for the owner (user) and group, we can use:
?- chmod(myfile, +ugx).
