I use the following to strip <CR>

tr -d '\015'

If this is in a script called rm_cr.sh for example you could 
do the following to strip <CR> from the file dos.txt:

  rm_cr.sh < dos.txt > unix.txt

DOS files have a ^Z as the last line, this should also be removed.

BTW, I find that doing an ftp with transfer mode set to ASCII
properly strips the carriage returns and ^Z automatically.

Hope this helps.

vi will read the file and display the carriage returns as ^M's.  You
can nuke these with this one-liner:

:s/^V^M$//

You'll be left at the bottom of the file, positioned just where you
would want to zap the ^Z.  Note that the ^V^M sequence above is ctrl-V
and ctrl-M.

> :s/^V^M$//

	I usually add a g to the end of this and get rid of the $ at the
	end of the pattern string, ie:

:s/^V^M//g

	this gets rid of all carriage-returns even when there are multiple
	ones on a line (some things embed more than one).

    I am trying the VI approach... thanks for all this help folks... but
    this is only stripping out ^M from the line on I'm on, it does not go
    through the entire file. What could be the cause? 4.0b unix using the
    c-shell.

If you have SoftWindows installed you can use the provided dostounix() command 
to strip the carriage returns (or the opposite unixtodos() to put them back).

:1,$s/^V^M//g

The "1,$" does all lines; the "g" does all occurrences in each line.

Or use the vi-clone "vim" which has "textmode" that automatically detects a
DOS-format file; ":set notextmode" will make it write the file in UNIX format.

Or use the tr command mentioned earlier; from within vi, you can invoke it

1G!Gtr -d '\015'

Explanation: 1G goes to the top of the file.  !G filters the entire file
through the following command.

Like most simple text processing problems, there are an almost infinite
number of ways to do the task in UNIX.

    How about the col(1) command.  It works great at
    fixing those ugly ^M's.
    
    Just do this...
    
    col -b < file_to_be_fixed > new_fixed_file
    
    Give it a shot right, from your unix prompt.
    
    The file names may need to be different, but
    the mv command can restore the original name.

Our version of col will make other changes to the file (from col(1)):

...
  -h  [Digital]  Compresses spaces into tabs. This is the default.
...

Moreover you can't turn this "feature" off.  The -h flag doesn't appear
to actually do anything.  (Perhaps the manual page should have added
the phrase "see figure 1".) :-)

This compression of spaces may or may NOT be desireable...



>    col -b < file_to_be_fixed > new_fixed_file
    
    
>    The file names may need to be different...

The file names WOULD need to be different.  When you redirect stdout to
a file, the shell first truncates that file to zero length if it already
exists.  So foo <input_file >input_file will wipe out input_file.

There is a public domain flip program (source available from gatekeeper) that
does the flip from UNIX to DOS and DOS to UNIX. I've used it on every UNIX box
I've ever worked on and have never had a problem with it.

I have the source code on my UNIX machine and also on my PC at home. When
transferring files between the two (via mtools, zip or whatever), all you need
to do is flip it to your host environment (flip -u == "to unix", flip -m == "to
msdos"). Note that you don't need to use the annoying "/" as the switch
delimiter, even when on DOS.

See http://ftp.digital.com/cgi-bin/grep-index?flip

    UNIX POWER TOOLS gave me the following which is in my bin directory as
    script.tidy and invoked as 
    
    	script.tidy <mumble.in >mumble.out
    
    #!/bin/sh
    # Public domain.
    # Put CTRL-M in $m and CTRL-H in $b
    # Change \010 to \177 if you use DEL for erasing
    eval `echo m=M b=H | tr 'MH' '\015\010'`
    exec sed "s/$m\$//
    :x
    s/[^$b]$b//
    t x" $*
