NAME
sa - Shell accounting
SYNOPSIS
sa [ -abcjlnrstuv ] [ file ]
DESCRIPTION
When a user logs in, if the Shell is able to open the file
/usr/adm/sha, then as each command completes the Shell
writes at the end of this file the name of the command, the
user, system, and real time consumed, and the user ID. Sa
reports on, cleans up, and generally maintains this and oth-
er accounting files. To turn accounting on and off, the ac-
counting file must be created or destroyed externally.
Sa is able to condense the information in /usr/adm/sha into
a summary file /usr/adm/sht which contains a count of the
number of times each command was called and the time re-
sources consumed. This condensation is desirable because on
a large system sha can grow by 100 blocks per day. The sum-
mary file is read before the accounting file, so the reports
include all available information.
If a file name is given as the last argument, that file will
be treated as the accounting file; sha is the default.
There are zillions of options:
a Place all command names containing unprintable characters
and those used only once under the name ``***other.''
b Sort output by sum of user and system time divided by
number of calls. Default sort is by sum of user and sys-
tem times.
c Besides total user, system, and real time for each com-
mand print percentage of total time over all commands.
j Instead of total minutes time for each category, give
seconds per call.
l Separate system and user time; normally they are com-
bined.
n Sort by number of calls.
r Reverse order of sort.
s Merge accounting file into summary file /usr/adm/sht when
done.
t For each command report ratio of real time to the sum of
user and system times.
u Superseding all other flags, print for each command in

the accounting file the day of the year, time, day of the
week, user ID and command name.
v If the next character is a digit n, then type the name of
each command used n times or fewer. Await a reply from
the typewriter; if it begins with ``y'', add the command
to the category ``**junk**.'' This is used to strip out
garbage.
