Apply Linux command recursively to all files in directory of single (.sh) type

Question

I am trying to apply this command sed -i -e 's/\\r$//' to all Shell ( .sh ) files in my directory I have tried:

sed -i -e -R 's/\r$//' *.sh

But this throws an unknown character error.

Any help would be great cheers!

Answer 1

This is an argument order issue. -e expects the expression/script as the next argument and you are giving it -R .

Swap those two arguments sed -i -e '....' .

That being said the dos2unix program exists for this purpose as well.
