Okay...just for completeness, here are two other solutions that don't use
the dos2unix binary.  The first one uses perl, and it's my favorite.

$ perl -p -i.bak -e 's/\015//g' filename

If you don't have dos2unix (but you do have perl), just put the following
in your .tcshrc:

alias dos2unix "perl -p -i.bak -e 's/\015//g'"

or if you're using bash put this in your .bashrc:
alias dos2unix="perl -p -i.bak -e 's/\015//g'"

If you don't have Perl, you can always use tr to strip the newlines.  If you
have GNU tr you can use this:

$ tr -d '\r' < filename > new_filename

If you have some older version of tr, this should always work:

$ tr -d '\015' < filename > new_filename
