Answer 1

Perhape this has suppressed UNIX warning message and worked creating the output file:

$ dos2unix -437 file.txt > file2.txt

Answer 2

You have saved your text file as a DOS/Windows text file. Some Unix text editors do not interpret correctly DOS/Windows newline convention by default. To convert from Windows to Unix, you can use dos2unix, a command-line utility that does exactly that. If you do not have that available in your system, you can try with tr, which is more standard, using the following invocation:

tr -d '\r' < input.file > output.file

Answer 3

This are windows new line chars. You can follow steps shown in this post to have correct this issue.

Answer 4

They are probably Windows carriage return characters. In Windows, lines are terminated with a carriage-return character followed by an end-of-line character. On Unix, only end-of-line characters are normally used, therefore many programs display the carriage return as a ^M.

You can get rid of them by running dos2unix on the files. You should also change your Eclipse preferences to save files with Unix end of lines.

Answer 5

You can remove those using dos2unix utility on a linux or unix machine. The syntax is like this dos2unix filename.
