Whitespace is only a problem if you type the whole command as a single string to a shell, which will split the string on unescaped whitespace to find a command and arguments. Quoted strings are also not split, so quoting user-provided arguments when they're used in shell scripts is easier than escaping them. If you're passing the arguments using NSTask, whitespace is not a problem. In fact, adding unnecessary quotes and/or escapes to NSTask arguments will *create* a problem, because NSTask - like everything *except* the command shell - uses arguments exactly as given, without processing quotes or escapes. sherm-- -- Cocoa programming in Perl: http://camelbones.sourceforge.net _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
