#print
You can also use the "=" command to find out what
the 'current' line is. Since the current line
is named '.', the appropriate command is
.=
and so if you say
3p
.=
the second command will print '3'. Since you should not
believe what I tell you without checking it, edit file
"doubt" and type the two commands above, which first
print line 3 (and incidentally set "." to that line) and
then ask what number "." is. Then type w, q, ready.
