The icon will display the image of the last message, and a count of the total number of messages in the spool file or mail folder. This will generate a single face icon showing the job at the top of the print queue, and the text message will display the printer name plus the number of jobs to be printed. Opening the window will show images of all the jobs in the queue. The text on each image can be toggled, choices being the owners' name and the size of the job in bytes. For each user, a face image is displayed.
Text can be either the username or the time they logged on.
The iconic form displays the total number of users. You can specify a program or shell script to run. The standard output from this program will be read by the faces program, and the appropriate faces displayed using the information provided. The format of this face information is given in the faces manual page. There is also an option to automatically update the faces database with this new image.
