checkmail — plays a sound file when the user receives mail
The checkmail program checks the status of the user's mail drop. If new mail is waiting, checkmail runs playbucket to play a sound and returns an exit status of 0. If mail has been cleared, an exit status of 2 is returned. If there has been no change, an exit status of 1 is returned.
The checkmail program is intended to be used with the checkCommand resource of xbiff. To set this resource, add the following line to your .Xdefaults file:
the user's mail drop
holds the previous mail drop size
audio file to play when there's new mail
playbucket(1), xbiff(1), nas(1)
