How do you search for files containing DOS line endings (CRLF) with grep on Linux?

Question

I want to search for files containing DOS line endings with grep on Linux. Something like this:

grep -IUr --color \'\\         


        

Answer 1

The query was search... I have a similar issue... somebody submitted mixed line endings into the version control, so now we have a bunch of files with 0x0d 0x0d 0x0a line endings. Note that

grep -P '\x0d\x0a'

finds all lines, whereas

grep -P '\x0d\x0d\x0a'

and

grep -P '\x0d\x0d'

finds no lines so there may be something "else" going on inside grep when it comes to line ending patterns... unfortunately for me!
