Remove ^M character from file

Nameesh — Tue, 13 Jan 2004 02:55:14 GMT

Hi,

I ftp'ed few files from my Windows machine to HP-UX machine. But, the *.ksh files contain
^M character. How can I get rid of the characters ? Is there a software that can be installed on UX box to convert all the files ?

Regards,
Nameesh.

Hi!

There's a Utility which is called dos2unix which is able to convert these Files.

There is a tool to remove these:

# dos2ux uncoverted_file > converted_file

There is a man page for this as well

# man dos2ux

It is part of the standard OS. it should be in /usr/bin or /usr/sbin

How else to find it:

# whereis dos2ux

# whence dos2ux

# find /usr -name dos2ux -print

When FTP is used to send ASCII files to a UNIX box, just send these files in ascii mode then you do not have to use the dos2unix tools.

ftp hostname
user password
ascii
put ascii.txt
quit

Hope this helps,

Hi,

Thnx for the input. But, the problem with the do2ux is that we need to copy the file into another file ie.,

dos2ux file1 > file2

file2 has got all the ^M character removed. So, need to perfomr one more step of copying file2 to file1 to have the original file with no ^M.

Please advice script for same.

Regards,
Nameesh.

simply:

# dos2ux myfile >myfile

will convert the original file and not save a copy.

Hi,

When I do the operation as :

dos2ux file1 > file1

Size of "file1" becomes "0" and there is nothing in file1.

Nameesh.

Hi,

vi /tmp/file1

:1,$s/+v +m//g

This replaces all special character(+v) ^M with nothing, multiple times per line. If you would have searched this subject would have returned at least 20 results.

did you try the FTP session using ascii mode? Then you won't need to convert dos2ux.

Hi,

yes, 'dos2ux file1 > file1' doesn't work proper.
Do 'dos2ux file1 > file2' and 'mv file2 file1' - tested ;-)

dos2ux $i >$i.new
mv $i.new $i
done

Hi,

Peter and Sanjay are right!!!
Sure, it is a text file and your problem just is that you transferred it in a type different than ASCII.
Anyway now you can use sed command to solve your problem, here like to do it by one command:

# sed 's/^M/ /' >

I hope this helps you.

Best regards,
Ettore

Hi,

Michael:ouch.. the shell creates an outfile always before starting the command. So indeed the command saves nothing. ;-))

Otherwise ascii ftp or sed or use another outfile and then rename as already posted.

BTW: are the ^M allways at the end?

greetings,

Michael

Hi,

you have 2 ways to get rid of this
1. open the file using vi
press
:1,$s/ctrl+v ctrl+M//
:wq (to save the file)

2. using sed

sed 's/^M//g'

Nameesh — Tue, 13 Jan 2004 08:01:36 GMT

Hi All,

Thanx for the inputs. I wrote a script which I used to solve the problem :

dos2ux $1 > tmp
mv tmp $1

As suggested many of you, while ftp'g the file from the Windows box we can set "transfer type as ascii" and ^M character wouldn't be there.

Regards,
Nameesh.

if you want to erase only ^M:

cat |tr -d \^M >
