- ac - Archimedes system usage accounting utility (c) Jason O'Broin
- Version 1.01 Last Update : 11/09/91
-
- ac is a system usage accounting program. It works by storing the time and date
- whenever the computer is switched on or off so that the total time used can
- be calculated.
-
- To achieve this, the command ac -n must be added to the boot sequence and
- the command ac -f added to the shutdown sequence. As as result, this utility
- pretty much requires a hard disk and that you use the desktop.
-
- For switching off, I recommend you use the utility !ShutDown (no idea who
- wrote this, but it's pd). Putting ac -f in the !Run file of this utility
- just before the run <shutdown$dir>.!RunImage line will do the trick.
-
- The utility also requies an operating system variable <ac$dir> to be setup
- to point to a directory where the file 'wtmp' can be stored. This file
- contains all the accounting information.
-
- To create the 'wtmp' file and start accounting, type ac -r. This will also
- store the time and date when the file was created.
-
- To display the amount of time used, *ac by itself may be used. However, using
- the option -p will display details of every entry in the file as well as the
- total time used.
-
- However, this file will grow without bounds if not periodically checked. The
- -t option will tidy the file. This counts the total time used to date, and
- stores this at the start of the file after the creation information. The
- file is also reduced to contain just these two entries.
