In a bash script, you can perform command substitution using either backticks (`) or the $(...) syntax. The latter is preferred for its readability and ability to nest commands.
Example using $(...) syntax:
#!/bin/bash
# Get the current date and time
current_date=$(date)
echo "Current date and time: $current_date"Example using backticks:
#!/bin/bash
# Get the current date and time
current_date=`date`
echo "Current date and time: $current_date"Both examples will output the current date and time when the script is executed. However, using $(...) is generally recommended for better clarity and ease of use.
