Hi,

I wanted to list all text files in my repo which contain carriage 
returns, so I tried the following command-line:

	git grep --cached -I -l -e <CR>

where <CR> is some magic incantation that I've yet to figure out. I've 
tried all the obvious cases (\r, 0x0d, \015, etc.), but none of them 
seem to DWIM...

The only working solution I've found so far is to create a file 
(named "cr") in a hex editor that contains exactly one CR byte, and 
then use the -f option to 'git grep':

	git grep --cached -I -l -f cr

Is there an easier way? And if not, should I try to create one (e.g. 
teaching 'git grep' to grok backslash escapes)?


Have fun!

...Johan

Inserting a literal carriage return seems to do the trick for me, in bash.

git grep --cached -I -l -e <Ctrl-V><Ctrl-M>

```

Thanks. That's exactly the incantation I was looking for. ;)

Why not use _literal_ CR; of course protecting it by piockung it by
shell as end of command by quites, for example

  $ git grep --cached -I -l -e '
  '

It works for me (bash).

In bash, $'\r' works too, and may be nicer to edit.
Better not use that with #! /bin/sh though.
