The "size" command is likely a command within a programming or scripting language that is used to get the size (i.e., length or number of elements) of the specified entity.
In this specific command, "${select}" and "${filename}" are variables that are being passed as arguments.
"${select}" refers to a variable that would hold a value indicating a specific selection or choice. The actual value of "${select}" would depend on the context in which this command is used.
"${filename}" refers to a variable that would hold the name or path of a file. Again, the specific value of "${filename}" would depend on how it is set in the code before this command is executed.
So, in simple terms, this command is likely used to get the size of a file whose name or path is specified by the value stored in the "${filename}" variable, based on a specific selection or choice indicated by the value stored in the "${select}" variable.
