Convert DOS/Windows line endings to Linux line endings in Vim - file

Question

If I open files I created in Windows, the lines all end with ^M.
How do I delete these characters all at once?

Answer 1

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.
There is documentation on the fileformat setting, 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 2

Change the line endings 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 line endings 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 *.cpp
do
vi +':w ++ff=unix' +':q' "$file"
done

Answer 3

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 4

I prefer to use the following command:
:set fileformat=unix
You can also use mac or dos to respectively convert your file to Mac or MS-DOS/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 5

:set fileformat=unix to convert from DOS to Unix.

Answer 6

:%s/\r\+//g
In Vim, that strips all carriage returns, and leaves only newlines.

Answer 7

In VIM:
:e ++ff=dos | set ff=unix | w!
In shell with VIM:
vim some_file.txt +'e ++ff=dos | set ff=unix | wq!'
e ++ff=dos - force open file in dos format.
set ff=unix - convert file to unix format.

Answer 8

From: File format
[Esc] :%s/\r$//

Answer 9

dos2unix can directly modify the file contents.
You can directly use it on the file, without any need for temporary file redirection.
dos2unix input.txt input.txt
The above uses the assumed US keyboard. Use the -437 option to use the UK keyboard.
dos2unix -437 input.txt input.txt

Answer 10

Convert directory of files from DOS to Unix
Using command line and sed, find all files in current directory with the extension ".ext" and remove all "^M"
# https://gist.github.com/sparkida/7773170
find $(pwd) -type f -name "*.ext" | while read file; do sed -e 's/^M//g' -i "$file"; done;
Also, as mentioned in a previous answer, ^M = Ctrl+V + Ctrl+M (don't just type the caret "^" symbol and M).

Answer 11

tr -d '\15\32' < winfile.txt > unixfile.txt
(See: Convert between Unix and Windows text files)

Answer 12

To run directly in a Linux console:
vim file.txt +"set ff=unix" +wq

Answer 13

The following steps can convert the file format for DOS to Unix:
:e ++ff=dos Edit file again, using dos file format ('fileformats' is ignored).[A 1]
:setlocal ff=unix This buffer will use LF-only line endings when written.[A 2]
:w Write buffer using Unix (LF-only) line endings.
Reference: File format

Answer 14

I found a very easy way: Open the file with nano: nano file.txt
Press Ctrl + O to save, but before pressing Enter, press: Alt+D to toggle between DOS and Unix/Linux line-endings, or: Alt+M to toggle between Mac and Unix/Linux line-endings, and then press Enter to save and Ctrl+X to quit.

Answer 15

The comment about getting the ^M to appear is what worked for me. Merely typing "^M" in my vi got nothing (not found). The CTRL+V CTRL+M sequence did it perfectly though.
My working substitution command was
:%s/Ctrl-V Ctrl-M/\r/g
and it looked like this on my screen:
:%s/^M/\r/g

Answer 16

With the following command:
:%s/^M$//g
To get the ^M to appear, type CtrlV and then CtrlM. CtrlV tells Vim to take the next character entered literally.

Answer 17

:g/Ctrl-v Ctrl-m/s///
CtrlM is the character \r, or carriage return, which DOS line endings add. CtrlV tells Vim to insert a literal CtrlM character at the command line.
Taken as a whole, this command replaces all \r with nothing, removing them from the ends of lines.

Answer 18

You can use:
vim somefile.txt +"%s/\r/\r/g" +wq
Or the dos2unix utility.

Answer 19

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

Answer 20

The below command is used for reformating all .sh file in the current directory. I tested it on my Fedora OS.
for file in *.sh; do awk '{ sub("\r$", ""); print }' $file >luxubutmp; cp -f luxubutmp $file; rm -f luxubutmp ;done

Answer 21

In Vim, type:
:w !dos2unix %
This will pipe the contents of your current buffer to the dos2unix command and write the results over the current contents. Vim will ask to reload the file after.

Answer 22

I wanted newlines in place of the ^M's. Perl to the rescue:
perl -pi.bak -e 's/\x0d/\n/g' excel_created.txt
Or to write to stdout:
perl -p -e 's/\x0d/\n/g' < excel_created.txt

Answer 23

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 24

From Wikia:
%s/\r\+$//g
That will find all carriage return signs (one and more reps) up to the end of line and delete, so just \n will stay at EOL.

Answer 25

This is my way. I opened a file in DOS EOL and when I save the file, that will automatically convert to Unix EOL:
autocmd BufWrite * :set ff=unix

Answer 26

If you create a file in Notepad or Notepad++ in Windows, bring it to Linux, and open it by Vim, you will see ^M at the end of each line. To remove this,
At your Linux terminal, type
dos2unix filename.ext
This will do the required magic.

Answer 27

I knew I'd seen this somewhere. Here is the FreeBSD login tip:
Do you need to remove all those ^M characters from a DOS file? Try
tr -d \\r < dosfile > newfile

Answer 28

This is a little more than you asked for but:
nmap <C-d> :call range(line('w0'),line('w$'))->map({_,v-> getline(v)})->map({_,v->trim(v,join(map(range(1,0x1F)+[0xa0],{n->n->nr2char()}),''),2)})->map({k,v->setline(k+1,v)})<CR>
Run this and :set ff=unix|dos and no more need for unix2dos.
the single arg form of trim() has the same default mask above, plus 0X20 (an actual space) instead of 0x1F
that default mask clears out all non-printing chars including non-breaking spaces [0xa0] that are hard to find
create a list of lines from the range of lines
map that list to the trim function with using the same mask code as the source, less spaces
map that again to setline to replace the lines.
all :set fileformat= does at this point is choose which eol to save it with, dos or unix
it should be pretty easy to change the range of characters above if you want to eliminate or add some
