Hi,

This sounds like homework... and the urgent in the title doesn't help your case

I will not explain in detail. I will only give you the necessary information to piece it together yourself.
Here goes :

Code:

$ man find
$ man wc
$ man rm

will tell you what the commands do.
the | symbol redirects the output of the first command to the second (in your case : the output of find to wc ).
pal1= is a variable assignment.
` ..... ` excutes ..... and returns the return value.

I'd recommend some reading about bash programming.

Ok, Same as before : use the 'find' command, take a look at the following options

-amin
-type
-exec

and look at the "mv" command. You got the ingredients now, time to cook
