Objective-C - How to convert file path to shell conform file path

I want to execute a shell command (I want to touch a file). I use system("shell command") to execute the command.

For example I want to touch the file at path /Users/username/New Folder/. Now I need to convert the NSString in a format that is conform to shell commands like /Users/username/New\ Folder.

Is there any method that does a conversion like this?

NOTE: It is NOT just replacing a whitespace with \. If you have a special character in the path like /Users/username/Folder(foo)/ the "shell path" looks like this /Users/username/Folder\(foo\)/

Don't use system. It's insecure and unpredictable. Surrounding the string with quotes is not sufficient.

Use the execve style functions instead. They are simple and secure.

You can enclose the parameters that contain spaces with " " marks.

touch "/Users/username/New Folder/"

At least this works at the shell prompt

There is no need to convert the path, you can surround it in single quotes. Just use:

touch 'path'
