Convert files from DOS line endings to UNIX line endings

Here "^M" is NOT "SHIFT+6" and "M". Type CTRL+V+M to get it instead.

Its shortest and easy. And its sed!, which is available by default in all linux flavours.. no need to install extra tools like fromdos.

Alternatives

There are 3 alternatives - vote for the best!

The old dos2unix from sysutils has been deprecated on Debian systems to this tool.

perl -pi -e 's/\r\n?/\n/g'

This method will also convert mac line endings.

Know a better way?

If you can do better, submit your command here.

What others think

I like sed too, just wish my version included the -i option. :) BTW, if you don't want to explain how to enter a carriage return, you can try this:

sed -i 's/'$'\r''//'

you should try the dos2unix command!

Comment by betsubetsu 270 weeks and 1 day ago

Adding a 'g' for global at the end to remove all instances of '^M" in the file.

sed -i 's/^M//g' file
