Well, TIMTOWTDI, however your version inserts extra spaces that were
not in the original file. This is why the tr alternate in the
handbook uses "tr -d '\r'". Also, the extra cat is not needed as
the handbook example shows:
tr -d '\r' < dos-text-file > unix-file
Personally, I normally recommend a slightly modified version of the
perl simply because many people I work with are also on Macs:
perl -pi.bak -e 's/\r\n|\r/\n/g' file
Or if you want the call style that the tr example uses, you can use:
perl -pe 's/\r\n|\r/\n/g' < dos-or-mac-text-file > unix-file
perl -e 'print unpack "u", "82G5S=\"!!;F]T:&5R(%!E<FP\@2&%C:V5R"'
