Turn on autoflushing ($|=1;) and return the carriage (\r) instead of moving to a new line (\n).

I would put the '\r' at the beginning not the end of the line: `print "\r$_/5" foreach (1..5); # and then: print "\n"; # or print ' 'x10, "\n";` [download] This places the cursor at the end of the line not at the start. In this small example this does not make any difference but if the loop takes a second or so to process the cursor will be visible. Also following lines would overwrite the last line otherwise, which is not always wanted.	[reply] [d/l]
