Today, you possibly can search the web for the utilization and examples of any command.
However it was not like this when the web did not exist, or it was not as broadly out there to everybody.
For that reason, instructions in Linux (and the working methods earlier than it) include a assist or guide web page (man pages). This labored as a reference and customers may entry it anytime to see what choices had been out there for a command and the way it labored.
The person pages are nonetheless related on this age of data abundance.
First, they’re the unique command documentation and therefore essentially the most trusted supply on command utilization.
Second, in case you are taking some Linux examination, you’ll not be allowed to look on the web however the man pages are at all times at your disposal.
Now that you simply perceive the significance of getting assist immediately within the terminal, let’s have a look at extra about them.
Get assist with Linux instructions within the terminal
There are two primary instructions to get assistance on the utilization of a Linux command:

Wait! What are shell built-in instructions?
You could really feel that instructions like ls, rm, mv are a part of the bash shell. However that is not true. Shell solely has just a few instructions which are constructed into it as part of the shell itself. That is why they’re referred to as built-in instructions. Some examples of built-in instructions are echo, cd, and alias.
Different standard Linux instructions like ls, mv, rm, cat, much less, and many others are a part of a software program bundle referred to as GNU coreutils. They arrive preinstalled on virtually all Linux distributions.
You will not discover man pages for the shell built-ins.
[email protected]:~$ man cd
No guide entry for cd
The person pages are for these ‘exterior’ Linux instructions. The shell built-ins have assist sections.
