Linux / Unix: Bash Shell Assign Printf Result To Variable

In Bash, you can use the printf command to generate formatted output, and you can assign the result to a variable using command substitution.

To do this, you can use the $() syntax to enclose the printf command, like this:

result=$(printf "Hello, %s\n" "world")

This will assign the string "Hello, world" to the result variable.

You can also use the $(()) syntax to perform arithmetic operations and assign the result to a variable, like this:

result=$((2 + 2))

This will assign the value 4 to the result variable.

It is important to note that the printf command and the $() syntax are Bash-specific features, and may not be available in other shells.

For more information on using printf and command substitution in Bash, you can consult the Bash manual or online documentation.
