pac —
printer/plotter accounting information
  
    | pac | [ -cmrs] [-Pprinter] [-pprice] [name ...] | 
pac reads the printer/plotter accounting files,
  accumulating the number of pages (the usual case) or feet (for raster devices)
  of paper consumed by each user, and printing out how much each user consumed
  in pages or feet and dollars.
Options and operands available:
  - -Pprinter
- Accounting is done for the named printer. Normally, accounting is done for
      the default printer (site dependent) or the value of the environment
      variable PRINTERis used.
- -c
- flag causes the output to be sorted by cost; usually the output is sorted
      alphabetically by name.
- -m
- flag causes the host name to be ignored in the accounting file. This
      allows for a user on multiple machines to have all of his printing charges
      grouped together.
- -pprice
- The value price is used for the cost in dollars
      instead of the default value of 0.02 or the price specified in
      /etc/printcap.
- -r
- Reverse the sorting order.
- -s
- Accounting information is summarized on the summary accounting file; this
      summarization is necessary since on a busy system, the accounting file can
      grow by several lines per day.
- names
- Statistics are only printed for user(s) name;
      usually, statistics are printed for every user who has used any
    paper.
pac formats the output into simple table, using four
  columns - number of feets or pages (column "pages/feet"), how many
  copies were made (column "runs"), total price for this print (column
  "price") and user login with host name (column "login" or
  "host name and login"). If argument name was
  not used and hence pac is printing information for all
  users, a summary line with print totals (runs, pages, price) is appended.
Note that pac on other system might print
    the price as price per copy.
  - /var/account/?acct
- raw accounting files
- /var/account/?_sum
- summary accounting files
- /etc/printcap
- printer capability data base
Thepac command appeared in
  4.0BSD.
The relationship between the computed price and reality is as yet unknown.
