Try to use a 'dir > text.txt', or 'ls > text.txt', or 'dmesg | grep a'
on the command line.

The symbols OptionPArse doesn't accept are reserved by the OS.

(| is the pipe in *NIX, && allows comamnd chaining in Windows and *NIX,
< and > are redirectors, which allow the use of a file as input to a
command, or direct the output of a command to a file, respectively.

There is no way *I* am aware of to circumvent these, except "Stop using
them". Maybe others know more.
