I'm playing around with the command line. For some reason when I try to grab lines 439 - 445 the output I am getting is lines 375 - 381 instead. I use the tail command to jump to line 439 then use the head command to print only the next six lines. Those aren't the six lines I get as shown in the screenshots below.
kali > tail -n+439 /etc/snort/snort.conf | head -n 6
Screenshots: grep grabbing wrong lines
What's the issue?
nl numbers non-empty lines by default. head or tail counts all lines.
Use cat -n (option not required by POSIX), grep -n '' or nl -b a -d '' to number all lines.
nl Line does not have anything to do with the tail Line, @Kamil Maciorowski. We do not know why it is still presented to us on the output. And yes, you were absolutely right, we would really be helped if we could see the Text instead of the Photographs.

WinXPCharacter String that appears on the Line #445 does not appear on the Line #381. You must have bumped onto a similar excerpt. – DOBRESCU_Mihai Dec 3 at 18:01grepdoes not select a continuous excerpt of lines, while thetail-headcombination does. – DOBRESCU_Mihai Dec 3 at 18:27
