Convert DOS line endings to Linux line endings in

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

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 above ^M = Ctrl+V + Ctrl+M (don't just type the caret "^" symbol and M)

Answer 2

if you create a file in NotePad or NotePad ++ in windows and 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 3

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 4

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 5

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.

Answer 6

Though this topic is very old, I'd like to put another stuff from wikia:

%s/\r\+$//g

that fill find all carriage return signs (one and more reps) up to the end of line and delete, so just \n will stay at eol.
