printf:tldr:532b5

This command is using the printf command to print a formatted string with the values of two variables var1 and var2.

Here is the breakdown:

• printf is a command used to format and print data.
• "${var1: %s\tvar2: %s\n}" is the format string. It defines how the output will be formatted. In this case, it includes two placeholders %s to represent where the values of var1 and var2 will be inserted. The \t represents a tab character and \n represents a newline character, which helps in formatting the output.
• "${$VAR1}" and "${$VAR2}" are the values being inserted into the format string. They represent the values of the variables var1 and var2 respectively. However, there seems to be a mistake with the syntax. It should be ${var1} and ${var2} without the $ before VAR1 and VAR2. The $ sign is used to expand the variable, so it should not be used again within the curly braces.

To correct the command, it should be:

printf "${var1: %s\tvar2: %s\n}" "${var1}" "${var2}"
