Archive-name: survey
[Not portable to System V directly. /etc/avenrun hook? ++bsa]
Survey, is a utility I use to generate a simple plot of system load
and number of users by time. I find it a very useful system management tool.
Survey requires the BSD uptime(1) command.
[I adapted this from a posting several years ago, I do not recall who
the originator was. This is almost a complete rewrite.]
Below is a sample of the output:(line width & scale are command line options)
['L' is load average value, 'U' is number of users logged on.]

Also included is, namedate(1), which I use to generate the current date
in a numeric, but human readable form. It makes a date of the form
YYYYMMDD, which sorts cronologically. I use it mostly to generate dated
filenames.
If you find any problems please tell me about them. If you port it to
any non-BSD system, please send me the changes.

X.SH SYNOPSIS
X.B namedate
X.RB "[ name ]"
X.SH DESCRIPTION
XIf no argument is given, the current date is printed.
XIf an argument is given, the argument followed immediately by
Xthe current date is printed. The format of the date is:
X.I 'yyyymmdd'
X, where
X.I yyyy
Xis the four digits of the year;
X.I mm
Xis the month number; and
X.I dd
Xis the day number in the month.
XFor example:
X.IP
X.B
Xnamedate junk
X.PP
Xprints
X.B junk19820429.
X.PP
X.B namedate
Xwith no argument is equivalent to
X.B namedate
