Convert line endings [duplicate]

Question

I have been using d2u to convert line endings. After installing Puppy Linux I noticed that it does not come with d2u, but dos2unix. Then I noticed that Ubuntu is missing both by default.

What is another way to convert line endings?

Answer 1

Some options:

Using tr

tr -d '\15\32' < windows.txt > unix.txt 

OR

tr -d '\r' < windows.txt > unix.txt  

Using perl

perl -p -e 's/\r$//' < windows.txt > unix.txt 

Using sed

sed 's/^M$//' windows.txt > unix.txt 

OR

sed 's/\r$//' windows.txt > unix.txt 

To obtain ^M, you have to type CTRL-V and then CTRL-M.
