dos2unix doesn't convert ^M
dos2unix, vim
Solution
`\r` denotes a carriage return, and on MAC it is used without `\n` to denote a line break. Are you sure the file is in DOS (`\r\n`) format and not MAC (`\r`)?
If VIM really turns out to be the only thing that'll repair your files, you can also invoke it as:
`vim somefile.txt +"%s/\r/\r/g" +wq`
This will open the file, perform the operation, save it, then quit.
Can you give us an example of the file, so that we can investigate further?
Problem
I exported results in a text file from a program running on Windows 7, and copied the file on Xubuntu 14.04. In a terminal, I ran `dos2unix file.txt`, which tells me `converting file out_mapqtl.txt to Unix format`. However, when I look at the file with `less`, I still see the Windows end-of-line as ^M, and `wc -l` returns me "0". I tried several things described here, but none works. I then opened the file in Vim and did `:%s/\r/\r/g` as explained there, which worked fine. So any idea why dos2unix didn't work? Would there be a way to avoid opening Vim every time?
