bash less it’s a fundamental command if you work on the Linux terminal.

Doing a “man less” you can see:

NAME
less - opposite of more

I love Gnu/Linux man pages, in this case it refer to more another command that do similar things (but less).

The Linux command less is similar to cat, but with less you can scroll the file instead of showing the file at once. With less command you can scroll up in the file as well as down, where with the Linux command more you can only scroll down the file.

This article/paper is just a starter so when newcomers start with bigger books don’t get overwhelmed without knowing the natural flow of the Linux system.

autoscan Sometime it’s useful to do an assessment of what’s online on your network, probably you think to know every server and service running, but I had more than one surprise in the past, with “test server just plugged in for a short time”, “New test service” or worst, hacked machine that exposed “new service”.

Network scanning is a procedure for identifying active hosts on a network, either for the purpose of attacking them or for network security assessment.
