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?
I know you have gotten this resolved, but I wanted to add a note for reference, based on some testing I've done.
If less is showing ^M, then like Sybren I suspect it is a MAC style ending (\r), not DOS (\r\n). You can determine that easily using cat:
$ cat -e filename
Use dos2unix to get rid of the DOS (^M$) endings
Use mac2unix to get rid of the MAC (^M) endings - dos2unix won't get rid of these.
I had a file where I had to use dos2unix and mac2unix to get rid of all the non-Unix endings.
