How do I convert dos files to linux files in vim?

Question

If I open files I created in windows, the lines all end with ^M.
How do I delete them all in once?

Answer 1

:%s/\r+//g

In Vim, that strips all carriage returns, and leaves only newlines.

Answer 2

:g/cntl-vcntl-m/s///

Answer 3

dos2unix is a commandline utility that will do this, or

:%s/^M//g

will if you use ctrl-v ctrl-m to input the ^M. Or you can:

:set ff=unix

and vim will do it for you. Docs on the 'fileformat' setting are here, and the vim wiki has a comprehensive page on line ending conversions.

Alternately, if you move files back and forth a lot, you might not want to convert them, but rather to do

:set ff=dos

so vim will know it's a DOS file and use DOS conventions for line endings.

Answer 4

You can use the following command:
:%s/^V^M//g
where the '^' means use "Ctrl" key.

Answer 5

With the following command:

:%s/^M$//g

Get the ^M to appear type Ctrl-V then Ctrl-M. Ctrl-V tells Vim to take the next character entered literally.

Answer 6

from: http://vim.wikia.com/wiki/Change_end-of-line_format_for_dos-mac-unix

[Esc] :%s/\r$//

Answer 7

I prefer to use the following command :

:set fileformat=unix

You can also use mac or dos to respectively convert your file to macintosh or MS-DOS/MS-Windows file convention. And it does nothing if the file is already in the correct format.

For more information, see the vim help :

:help fileformat

Answer 8

:set fileformat=unix to convert from dos to unix.

Answer 9

Change the lineendings in the view:

:e ++ff=dos
:e ++ff=mac
:e ++ff=unix

This can also be used as saving operation (:w alone will not save using the lineendings you see on screen):

:w ++ff=dos
:w ++ff=mac
:w ++ff=unix

And you can use it from the command-line:

for file in $(ls *cpp)
do 
  vi +':w ++ff=unix' +':q' ${file}
done

Answer 10

I typically use

:%s/\r/\r/g

which seems a little odd, but works because of the way that vim matches linefeeds. I also find it easier to remember :)

Answer 11

Usually there is a dos2unix command you can use for this, just make sure you read the manual as the GNU and BSD versions differ on how they deal with the arguments.

# BSD version
dos2unix $FILENAME $FILENAME_OUT
mv $FILENAME_OUT $FILENAME

#GNU version
dos2unix $FILENAME

Alternatively, you can create your own dos2unix with any of the proposed answers here, for example:

function dos2unix(){
    [ "${!}" ] && [ -f "{$1}" ] || return 1;

    { echo ':set ff=unix';
      echo ':wq';
    } | vim "${1}";
}

Answer 12

dos2unix can directly modify the file contents.

you can diretly use on the file. no need for temp file redirection

dos2unix input.txt input.txt

the above uses the assumed US keyboard use -437 option to use the UK keyboard.

dos2uinx -437 input.txt input.txt

in solaris we can use dd command also.
