What is a Shell Prompt in Linux ?

The prompt, $, which is called the command prompt, is issued by the shell. While the prompt is displayed, you can type a command.

Shell reads your input after you press Enter. It determines the command you want executed by looking at the first word of your input. A word is an unbroken set of characters. Spaces and tabs separate words.

Following is a simple example of the date command, which displays the current date and time:

$date
Thu Jun 25 08:30:19 MST 2021

If you're setting up partitions on your main Linux boot drive, you'll also want to create a swap partition of at least a few GBs in size when setting up those partitions. This partition is used for "swap space". It's similar to the paging file on Windows. Linux swaps out memory to the swap space when its RAM is full. This partition must be formatted as "swap" instead of with a particular file system.

Logwatch comes with a tiered approach and there are 3 main locations where configuration details are defined:

  • /usr/share/logwatch/default.conf/*
  • /etc/logwatch/conf/dist.conf/*
  • /etc/logwatch/conf/*


To install Logwatch on your server.

On Ubuntu:

$ sudo apt-get install logwatch

On Debian:

$ apt-get install logwatch

This article covers how you can easily change the sudo password timeout by adding a single entry in the sudoers file. If you are using Vi instead of Nano, follow the instructions described here.
You use sudo for some command in the terminal, it asks for the password.

You enter the password, the command runs.
For the subsequent commands, even if they need superuser privileges, you don't need to enter the password again.
After a certain amount of time, when you try to use sudo, it asks for the password again.
It happens because there is a default timeout in Ubuntu and other Linux system for Sudo. In Ubuntu, this default sudo timeout is 15 minutes.
If you think 15 minute is too short or too long you can even change the sudo password timeout in Ubuntu.

To Change sudo password timeout in Ubuntu:
1. Open a terminal (Ctrl+Alt+T) and use the following command:

$ sudo visudo

It will open a file in nano text editor that contains some settings related to sudo.
In here look for the following line:

Defaults        env_reset

Replace above line with this one:

Defaults        env_reset, timestamp_timeout=XX

Where XX is the new timeout value in minutes.
Of course you have to replace the XX with the desired timeout value.
2. Once you are done changing the default sudo password timeout, use Ctrl+X to exit the editor.
It will give you option to save or cancel the changes.

Use Y to save the changes.
