sa -- Command

Print a summary of process accounting
sa [-abcjlmnrstu] [-v N] [file]

One  of  the accounting  mechanisms  available on  the  COHERENT system  is
process  accounting  (also  called  shell  accounting), which  records  the
commands executed  by each  user.  The  command accton enables  or disables
shell accounting.

The  command sa  scans  the accounting  information  in file  and prints  a
summary.  If  file is omitted, it reads the  file /usr/adm/acct by default.
For each  command executed, sa prints  the number of calls  made, the total
CPU time (user and system), and the total real time.  The output is ordered
by decreasing CPU time.

sa recognizes the following options:

a   Place commands  executed only once  and command names  with unprintable
    characters in the category ``***other''.

b   Sort by average CPU time per call.

c   Also print CPU time as a percentage of all CPU time used.

j   Print average times per call rather than totals.

l   Separate user and system time.

m   Accumulate information for each user rather for each command.

n   Sort by number of calls.

r   Reverse the order of the sort.

s   After  scanning, condense  the accounting  file and  merge it  into the
    summary files.

t   Also print the CPU time as a percentage of real time.

u   Print  the user  and command  for each  accounting record;  this option
    overrides all others.

v N For commands called  no more than N times, where  N is a digit, sa asks
    whether to place the command in the category ``**junk**''.

sa uses  the summary files /usr/adm/savacct  and /usr/adm/usracct to lessen
disk usage.

Notes

The  file  /usr/adm/acct  can  become  very  large; therefore,  you  should
truncate  it  periodically.   Special  care  should  be  taken  if  process
accounting is enabled on a COHERENT system with limited disk space.
