To me it seems almost impossible to implement this on the Amiga without the cooperation of the program writing to the file.

Yes, I've written one and I'll put it on ab20.larc.nasa.gov for anon-FTP. | usage: tail [+|-[n][lbc]] [file] | All options enclosed in braces are optional! | | + -begin output at line n (display all lines after the first [n-1] lines). | - -display last [n] lines/blocks/chars (DEFAULT) | n -number of lines (DEFAULT is 10), blocks or characters | l -lines (DEFAULT) | b -blocks (512 bytes/chars) | c -chars (characters) | file - filename of the file you want to display (very quick) | | If you want to display the end of a file, type: "tail filename" and "tail" | will display the last ten lines of "filename".
