How to set a variable to the output of a command in Bash

In Bash, you can set the output of a command as the value of a variable by enclosing the command within $() or backticks `.

For example:

# Using $()
echo $result

# Using backticks
echo $result

In the above example, the date command returns the current date and time. The output of this command is then captured in the result variable using $() or backticks. Finally, the value of the result variable is printed to the console using the echo command.

You can use this method to assign the output of various command-line programs to a variable to store, manipulate or use in other parts of your Bash script.
