Pedant point of the day. Be careful of combining the -n and -p flags
on the perl command line, as they mean contradictory things. '-n' is
loop over all the lines of the input *without* printing then, whereas
'-p' is loop over all the lines of the input and print them to stdout.
The command as written will work, for as perlrun(1) says:
A -p overrides a -n switch.
but it would be better to write the command as:
perl -i.bak -pe 's/\r\n/\n/g'
Cheers,
Matthew
