Line ending issue DOS > Linux > Java

问题

I'm having a bit of a trouble with a 160.000 lines file, this file was generated through an export from an xlsx file, it has a .txt extension but i'm afraid that it has been exported as DOS-like file, at the end of each line it has the DOS line break. I'm using a parser written in java, running on an Ubuntu environment, and i'm getting this when i run the parser (which i cannot edit because its part of a jar i cant access the source code), i get NumberFormatException where a number is expected, my line ends like this:

4449

But the parser sees it as

For input string: "4449&#xd;"<

Do you have a solution for this? again i cant access the parser myself, i will have to edit the file "on my Ubuntu machine" and remove those line ends.

回答1:

Try using the dos2unix command on that file. That should fix the line terminators.

> dos2unix winfile.txt unixfile.txt

Reference:
dos2unix man page

回答2:

The parser is finding 
, which is a windows carriage return; however, it is unable to parse these characters. Go to the file and run a quick command tr -d '\15\32' < winfile.txt > unixfile.txt.
