Delete the character sequence \r\n on linux using tr/sed etc

Question

I am trying to delete the string '\r\n' from a file.

Using sed:

cat foo | sed -e 's/\015\012//'

does not seem to work.

tr -d '\015'

will delete a single character but I want to remove the string \015\012. Any suggestions?

Do you have `\r\n` like return\newline, or do you have the character `\r\n`. Give example text before and after. — Jotne, Jun 05 '14 at 06:27
you want to put a full text fill from Windows/Dos format to 1 line ? or convert to a unix text file (leaving newline) ? — NeronLeVelu, Jun 05 '14 at 06:57

If I can offer a perl solution:

$ printf "a\nb\r\nc\nd\r\ne\n" | perl -0777 -pe 's/\r\n//g' | od -c
0000000   a  \n   b   c  \n   d   e  \n
0000010

The -0777 option causes the entire file to be slurped in as a single string.

What about:

sed ':a;N;$!ba;s/\r\|\n//g'

This is to remove any \r and \n characters. If you want the sequence \r\n, then use this:

sed ':a;N;$!ba;s/\r\n//g'
