.TH "ttyload" "1" "2001-08-24" "" ""
.SH "NAME"
ttyload \- a tty-based xload equivalent
.SH "SYNOPSIS"
.PP
ttyload [options]
.PP
.SH "DESCRIPTION"
.PP
ttyload is a "tty" based load monitoring tool\&. Not entirely unlike
xload, it plots a graph of a system's "load average" data\&. Unlike
xload, it uses 3 line graphs to plot things, instead of a single fill
graph, so that it can show you not only the 1-minute load average, but
also the 5-minute and 15-minute averages\&. Also unlike xload, it uses
a basic terminal (tty) to display the information, instead of an X
window\&. ANSI escape sequences are used (optionally) for colorization
and screen manipulation\&.
.PP
A few of the main features of ttyload are:
.PP
.IP o
graphs load averages (all 3 numbers) over time
.IP o
uses ANSI escape sequences to colorize graphs
.IP o
works without requiring X11 libraries, in a Terminal window
.IP o
automatically determines screen size by default
.PP
\" .SH "GENERAL"
\" .PP
\" See DESCRIPTION\&.
\" .PP
.SH "USAGE"
.PP
The easiest way to use ttyload is just to invoke the command, with no
additional options\&.
.PP
Additional options are described below\&.
.PP
To quit ttyload, enter the terminal's interrupt character (typically
control-C)\&.
.PP
\" .SH "EXAMPLES"
\" .PP
\" Here are some examples of how I use ttyload\&.
\" .PP
\" No examples written\&.

.PP
.SH "OPTIONS"
.PP
ttyload uses standard getopt() style options processing\&.
Available options are:
.PP
.DS
.PP
.IP "\fB-h\fP"
Display a brief usage statement ("help")\&.
.IP "\fB-v\fP"
show version info, then exit
.IP "\fB-m\fP"
monochrome mode (no ANSI escapes)
.IP "\fB-c <cols>\fP"
Sets the number of columns wide to make the display
.IP "\fB-r <rows>\fP"
Sets the number of rows high to make the display
(these two options combine to override the default behavior of
auto-determining screen size)
.IP "\fB-i <seconds>\fP"
Alter the number of seconds in the interval between
refreshes\&. The default is 4, and the minimum is 1, which is silently
clamped\&.

.SH "VERSION"

.PP
.SH "THANKS"
.PP
Thanks to several my friends for testing things out on various
platforms, or lending me accounts on their machines upon which
to do porting\&.

.SH "AUTHOR"

including bug reports and patches, to me\&. My contact information (as
