<P>The rmv script asks if you're sure you want to empty the trash. If you type an n, the

delete is aborted. If you type a y, the trash is deleted. Because the letter e was found on

the command line, the empty variable was set to true and the statements following the

if ... then test line were run. The script prints a message to your display, and then, using the

read command, waits for you to enter an answer. The answer is then tested, and if yes, the

files in the .trash directory are deleted.

</P>



<P>Using the shell, you can quickly build simple programs to accomplish major tasks. Feel

free to improve this program by adding features or improving on how file names are

handled at the command line. One such improvement may be to add the ability to handle

wildcards or whole directories. See the bash manual page for more information about other

shell commands and operators you can use in your own shell scripts.

</P>
