Pipe it through  'col -b'

col <infile >outfile

perl -npe 's/\015//g' < infile.cgi > outfile.cgi

perl -i -p -e 's/\r$//' your files

fromdos

dos2unix

tr -d "\r" < dosfile > outfile

Emacs "replace-regexp".  
you can enter the control character ^M by typing ^Q^M.  When asked what
to replace it with, just hit return.


The vim editor has a neat feature:  if you edit the file and ":set ff=unix"
the file will be saved without CR caracters, and if you ":set ff=dos" it
will save the file with CR characters.

Otherwise, most vi version can do ":%s/^V
$//" as the equivalent of the
emacs command above.
