Hey there,
tail -n + NUM does not return the desired output. +NUM starts from the top
of the file, not from the bottom.
So for example, given the following file:
this
is
an
example
file
each
word
represents
a
line
and executing tail -n +3 example, I am getting
example
file
each
word
represents
a
line
instead of
this
is
an
example
file
each
word
I am using *tail (GNU coreutils) 8.28 *in latest ubuntu 18.04 LTS
Thanks in advance for looking into this :)
Isn't this exactly what tail(1) is support to do when the user explicitly
passes the '+' sign to the number?
$ tail --help | grep -A1 -- --lines
-n, --lines=[+]NUM output the last NUM lines, instead of the last 10;
or use -n +NUM to output starting with line NUM
Also POSIX says so:

Have a nice day,
