Hi, do You need to edit the output? Redirect it to some tempfile and edit it,
Code:
tail -500 bigfile > /tmp/tempfile; vi /tmp/tempfile
Otherwise view it with less, like in
Code:
tail -500 bigfile | less
or view it continuously with less,
Code:
less +F bigfile
And there are more ways... Your example doesn't work because You pipe the output of tail to small_file and Your shell believes that to be a command, but I guess it isn't. I think a redirection is what You want.
