The first line of what? He didn't give any filenames to the tail
command, so it's going to read from stdin (the terminal if he's entering
these commands interactively). And he *is* giving a filename argument
to grep, so it's going to read that file rather than the output of tail.

Maybe what he meant was:

tail +2 /home/usr/.../filefgd.asc | grep -iv '[a-z]' >
/home/usr/.../tmp.asc
