Re: [TCLUG:1906] Shell Script Question -- CR/LF

[Luke Francl <fran0382@tc.umn.edu>]

Hi All.  I work in a Windows 95 environment making and modifying HTML
documents to go on a Unix server. This of course means I am plauged with
the CR/LF nonsense constantly. Whenever I download a page to work on
offline, Windows goes and adds another ^M to the end of the line --
after several edits there can be a page of returns between every line of
text. I have tried to keep this crap to a minimum by saving files in
"unix" format in Homesite 3.0 (our development tool), but that doesn't
completely eliminate the problem. Also, our unix sysadmin is well...a
moron, so there are no real tools installed on the server (no X, no
emacs, not even pico...hell, less isn't even installed), and no ability
to install them myself. Vi is the only editor I have avalible. 

This helps me somewhat (just last week I tried to figure out how to get
vi to remove the accurssed ^M's, unsuccessfully):

But what I would like to do is write a shell script to remove the ^M
from every file in a directory. Brad says tr can be used for this, but I
have no experience with this tool...what parameters would I need to give
it in order to make this work?
