How to remove strange return-commands ?

How to remove strange return-commands ?

[Martin Horoba]

Hi,

I want to get some files from noEmacs-windows-editors into Linux GNU
Emacs Editor.

But you cannot work because of "strange" return-commands from windows
in these files (->  ^M ).

How it's possible to remove/replace these commands with Emacs or any
other tools in Unix-Systems ?
(with the Emacs-replace-function you cannot find ^M)

Thanks for Help,
	Martin

Those are carriage return characters (decimal value 13).  If you were searching for an up arrow (shift 6) followed by an M emacs will not match that with a carriage return.
Try this to match them:  C-Q C-M
This will insert a carriage return character into the search string.

I have seen much discussion on removing these from a buffer.  I am certain that there are many packages available to do this.  Since I wrote my own function before I discovered emacs packages I have not paid much attention to them.  You might want to take a look at the packages list at http://www.emacswiki.org/elisp/.  Or you could look in the archives of this list.  (My function is not quite ready for primetime).

I made a keyboard macro out of this which removes all ^M and saves the file.

;strip MS-DOS carriage return from file thus:
;1. goto top of file, 2. S-M-% C-Q C-M <RET> <RET> ! 3. C-x s
(fset 'stripCR
   [home ?\M-% ?\C-q ?\C-m return return ?! ?\C-x ?\C-s])
(global-set-key [f11] 'stripCR)

For RedHat & Cygwin the dos2unix utility works nicely.  When uploading bash
scripts (for instance) from an M$ box to a RH Linux box, I run...
     dos2unix -k *.sh
...and that removes the carriage returns from all scripts ending in '.sh'.

Other *nix OSes use something else as I noticed in a post in this
group some time in the past month.

Many people use perl to do this. The perl script is about 3 lines long
(actually, you can probably do it in one line). 

I'm wondering though - perhaps you can achieve the desired behavior by
playing around with the various coding style settings? I have'nt tried
it, but it may be worth looking at.
