Wildcards

     

In the previous chapter, you learned about the file maintence commands cp, mv, and rm. Occasionally, you want to deal with more than one file at once--in fact, you might want to deal with many files at once. For instance, you might want to copy all the files beginning with data into a directory called ~/backup. You could do this by either running many cp commands, or you could list every file on one command line. Both of these methods would take a long time, however, and you have a large chance of making an error.

A better way of doing that task is to type:

screen5560

As you can see, the asterix told cp to take all of the files beginning with data and copy them to ~/backup. Can you guess what cp d*w ~/backup would have done?
