I was especially befuddled as I first manually copied and pasted the Fcntl man page to a test file and did "cat testfile | sed -n 4p", which produced "Fcntl - load the C Fcntl.h defines" instead of the above. But then I did a "man Fcntl | sed -n 1,10p > testfile" followed by "hexdump -C testfile", and sure enough, there are three line feeds before what I thought was the first line. Oddly enough, this doesn't seem to be the case with all man pages; "man man | sed -n 1,10p | hexdump -C" shows no leading LFs. Just out of curiosity: Why is this? And how come that man(1) seems to ignore leading line feeds when rendering the man pages? Thanks and regards, --ropers
