I don't know what you mean. On Linux (or other UNIX-like operating 
systems), you specify the command line parameters as an array of strings 
when executing an external program. There is by definition no "messing 
about" with strings. Whatever syntax the shell uses to escape quotes and 
backslashes is irrelevant to ProcessBuilder, as it doesn't use the shell 
to start programs, but rather invokes some flavor of the exec function 
directly.
