How to use `while read` (Bash) to read the last line in a file if there's no newline at the end of the file? - Stack Overflow

The basic issue here is that read will return errorlevel 1 when it encounters EOF, even if it'll still correctly feed the variable.

So you can use errorlevel of read right away in your loop, otherwize, the last data won't be parsed. But you could do this:

eof=  while [ -z "$eof" ]; do      read SCRIPT_SOURCE_LINE || eof=true   ## detect eof, but have a last round      echo "$SCRIPT_SOURCE_LINE"  done

If you want a very solid way to parse your lines, you should use:

IFS='' read -r LINE

Remember that:

• NUL character will be ignored
• if you stick to using echo to mimick the behavior of cat you'll need to force an echo -n upon EOF detected (you can use the condition [ "$eof" == true ])
