Is there a problem with a command?

On UNIX platforms, be careful when including special characters, for example, back slash (\) and double quote (") characters, in descriptive text for some commands. If you use either of these characters in descriptive text, precede them with a \, that is, enter \\ or \" if you want \ or " in your text.

See Characters allowed in commands for more information about commands.
