NAME

loadst − print current time and load statistics. 

SYNOPSIS

loadst [−n] [−a] [−x] [−t] [−u] [interval]

DESCRIPTION

loadst is an Emacs helper utility used to drive a mode-line clock for Emacs.  It indicates whether you have new mail, prints the current time, and can display load average, disk-usage and cumulative cpu-time statistics. 

OPTIONS

With no arguments,  loadst prints the word "Mail" if you have new mail, or nothing if you do not.  Specifying flags adds other information to the display as follows:

-adisplay system load average

-xdisplay disk transfer statistics

-tprint the current time

If you specify a decimal interval argument, loadst will go to sleep and produce its output every interval seconds.  If no interval is specified, loadst prints once and exits. 

-nprevents a newline from being added to the end of the status line.  Otherwise,  a newline is appended. 

-ucauses it to use your real uid rather than the value of the USER shell variable (which may not be defined on non-BSD systems) to figure out the name of your mail file. 

NOTE

In order to produce the load, disk, and cpu-usage statistics, loadst must be able to read /dev/kmem.  If /dev/kmem is protected against unprivileged users, you must run loadst setuid or setgid so it can read /dev/kmem.

BUGS

The options must be given one per word, as in "-a -t" rather than "-at".  This is not considered to be a problem, since loadst is intended to be invoked by time.ml, and not interactively.
