Hi

If you copied the file from a PC then put it through dos2ux

in vi

:1,$s/cntrlVcntrlM//

cntrlV = Control+v
cntrlM = Control+m

Hi, the ^M is a DOS CR/LF identifier. I guess the file has been modified on a DOS/Windows PC at some time. To remove from within vi try:

: 1,$s/^M//g

N.B For ^M press Ctrl+v then imediatltly press m

Sorry Steve got it right, you need to keep the CTRL pressed i.e ctrl+v ctrl+m.

Silly thing was I actually tested before I sent the reply.

Inside vi, press:
!Gcol -bx

See what happen?

Hello Idris,

You can do this within vi

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

(NOTE You need the ^V then ^M
in order to enter the ^M charatcer)

This will erase the ^M character from each line.

HTH,

John

see man dos2ux.

If you get it from Win and ftp use ascii mode.

Hi,

...or you could do this in vi:

:%s/.$//

to remove the last char from every line.

Rgds, Robin.

in vi

:%s/cntrlV invio//g

with cntrlV you can insert ^M with invio.

Hi

Another solution

Problem Description

I have transferred a file from another system, and I am editing the file
with the vi editor. The file has embedded carriage returns, which the
editor is displaying as ^M. How can I remove these extra characters?

Configuration Info

System 9000 HP-UX

Solution

Use the tr(1) command to remove these characters from the file.
First, quit the vi editor and then do the following:

Execute the tr command:

1. tr -d \\015 < inp_file > new_file

2. Inspect the file new_file with vi to check that the ^M's are gone.

Care should be taken when attempting to remove ^M from a file in vi. You really should anchor it to the end of line. I have really hosed up shar files w/o doing this when there was a ^M but it wasn't meant as a LF/CR.

%s/^V^M$//g

Should take care of your anchor.
