There are a few different ways to convert a DOS file to Unix format, but the most available is probably this:

$ col -bx < dosfile > unixfile

If you're using os.system to run a command (such as xterm running man) and you get "broken pipe" errors, you can restore standard pipe functionality with the signal module:

import signal
signal.signal(signal.SIGPIPE, signal.SIG_DFL)

# Call os.system after calling signal.signal.

Given an array @slobber, replace all the CR-LF with CR:

foreach (@slobber) {
   s/\015\012$/\n/; print;
}
