Linux / Unix: Bash Shell Assign Printf Result To Variable

last updated in Categories

How do I assign printf command result to a shell variable under Unix like operating systems?

The printf command syntax is as follows:

printf "FORMAT" var
var=$(printf "FORMAT" var1)
var="$(printf "FORMAT" var1)"

Examples

Type the following command:

dir="/home/httpd" 
printf "%s\n" $dir

To store result to a variable called j, enter:

dir="/home/httpd" 
j=$(printf "%s" $dir)
echo "$j"
printf "%s\n" $j
