Bash Scripting: Using variable filenames

In this video we look at a bash script in which we write to a file with the name of said file coming from a variable. The first example is nearly trivial, we assign a string value to a variable and then use that variable in a command that expects a filename argument. In the second example, the value assigned to the variable includes the formatted output from a date command. So the output of the script varies in that it would name the resulting file differently on different days. (It might be useful for logging or backing up.)
