Question

I copy pasted some enum values from my IntelliJ IDE in windows to notepad, saved the file in a shared drive, then opened it up in a linux box. When I did cat -A on the file it showed something like:

A,B,C,^M$
D,E,F,^M$
G,H,I,^M$

After searching around I figured that ^M is the carriage return and $ means the last line of the file. I’m just puzzled at how this file is able to have multiple $’s.

Answer 1

$ is the end of line marker with cat -A, not end of file.

This is indicating the file has Windows-style line endings (carriage return followed by line feed) and not Unix-style (only line feed).

(You can convert text files from one format to the other using the programs dos2unix or unix2dos.)
