stripping control characters from line !!!!

[Henrique Silva_3]

Now, I have done this in vi before but have not done in a long time, so, here is my questions. How do you strip control character from the end of the line on a file ? This happens usually when you ftp a file back and forth from a windows machine to unix.

so, you will have file such as :

line 1^M
line 2^M

For the life of me, I tried all kinds of sed commands, inside vi, such as
:1,$s/\^M//g

etc, but nothing seem to work. What kills me is that I had the same problem some 10 months ago and did it without thinking !!! I must be getting old :-(((

A search on google or looking at my vi book did not help either :-(((

Can somebody shed some light out there ???

Thanks

Hi,

If your copying files back and forth
from a dos box, there are two utilities
that are available for this. The first
is 'dos2ux' which is for files coming
from dos to Unix. The second is 'ux2dos'
which of course goes from unix to dos.

You could use the vi method or even sed
but why bother when you can use these.

Hi Henrique,

First thing, always ftp text files in ASCII mode. That way you don't have to be concerned with whether or not the files have the LF-CR in Windows and only LF (actually referred to as NL - newline) in UNIX.

If you do get a text file in UNIX from Windows that was transferred in binary mode, simply run dos2ux file >newfile

Inside of your vi session enter

:%s/^M//g

where ^ is cntl-v and M is cntl-shift-M

and tada... gone.

Thanks for the replies, especially the last one, which gave me the sed syntax. That was really what I was looking for, but will take a look at the utilities to convert files back in forth. I was not aware of them.

No comprende. No apunta para mi? Excusa mi espanol.
