variable assignment

printf is a command in Linux Bash that allows you to format and print data. Unlike the echo command, printf provides greater control over the format of the output, making it possible to specify the type of data and its presentation. What does the -v option do with printf? In Bash, the -v option with printf allows you to assign the formatted output to a variable instead of printing it to the standard output. This is particularly useful in scripts where you need to format some data and then use it later without displaying it immediately.
