I have a file that contains both CRLF in it and also LF in it. I am trying to delete the CRLF from my file. The other pre-existing LF in my file, I would like to remain behind. I'm having trouble because either it seems sed can't identify CRLF, or because tr delete both CRLF and LF at the same time. I've trie, 

```
tr -d '\r\n' <file.txt> file2.txt

```

it is also deleting the LF in my file as well. I tried deleting only \r but then the LF from the CRLF gets left behind. I want CRLF to be deleted or at least turned into a space, but the row doesn't end.

Any help?

I've tried:

```
tr -d '\r\n' <file.txt> file2.txt

```

I've tried sed as well but I'm not able to find CRLF.
