NAME
rclock (ouR CLOCK)
--- clock and appointment reminder for X11
SYNOPSIS
rclock
[options]
DESCRIPTION
rclock
--- version
2.6.3
--- is an analog clock for X intended as an
xclock(1)
replacement that conserves memory and has extra features:
rclock
enters reverse video if there is mail waiting; an appointment reminder
is also builtin.
OPTIONS
The options supported by
rclock:
-display displayname
Attempt to open a window on the named X display.
In the absence of this option, the display specified by the DISPLAY
environment variable is used.
-geometry geom
Create the window with the specified X window geometry [default 80x80].
-bg color
Window background color [default white].
-fg color
Window foreground color [default black].
-fn fontname
Select font used for reminders [default 7x14].
-iconic
Start iconified, if supported by the window manager.
-adjust ddhhmm
Adjust the clock by +/-
ddhhmm
(dd
= days,
hh
= hours,
mm =
minutes) to fix an incorrect clock without being root or for working in
another time-zone.
-update n
Update clock face every
n
seconds [default 30].
If
n=1,
a seconds hand is displayed.
-mail n
Check for new mail every
n
seconds [default 60].
The actual interval is a multiple of the clock update interval.
#geom
Specify the preferred icon window size [default 65x65].
X RESOURCES
No X resources are used --- only command-line options.
TITLES AND ICONS
The window and icon titles are set to the day of the week and the date.
The icon window is "active" and will show the time, if supported by
the window manager.
REMINDERS
The
~/.rclock
file lists the messages to display and/or the programs to run at
specified times and dates.
At the specified time,
rclock
will pop-up a window in the center of the screen to display the
message or will simply run the scheduled program.
rclock will reads the~/.rclock
file at startup, and every 10 minutes (to look for changes) and after
a message window has been dismissed (to find the next appointment).
An entry in
~/.rclock
may be one of two formats (blank and comment lines will be ignored):
hh:mm [dd] MM/DD/YY message[; program]
or
[hh:mm [dd] MM/DD/YY [message]]; programhh - hour (0-23; * = current)
mm - minute (0-59; * = 0)
dd - days-of-week (some/all/none of umtwrfs; * = all)
MM - month (1-12; * = current)
DD - day of month (1-31; * = current)
YY - year (0-99 or 1900-????; * = current)
message - message to display
program - program to execute
The days-of-the-week use the following abbreviations:
u=Sunday,
m=Monday,
t=Tuesday,
w=Wednesday,
r=Thursday,
f=Friday,
s=Saturday,
*=all.
If
message
is empty and
program
has been specified, it is executed without a dialog box.
If time/date are also not specified,
program
is executed on start-up.
Note
message
may contain escape values (\n: newline, \;: semicolon).
Here's a silly example file that shows some of the permissible
constructs:
# ~/.rclock - My appointment file
# startup functions
; xsetroot -solid Black &
# cron functions
10:00; xsetroot -solid Grey25 &
14:00; xsetroot -solid Grey75 &
# daily/weekly reminders

08:30 03/15/1999 Dentist appointment

ENVIRONMENT
rclock
uses the environment variable
MAIL
to determine the location of the user's mail spool file.
BUGS
rclock
is not very smart about dealing with errors encountered while reading the
~/.rclock
file.
Each reminder must be a single line not exceeding 255 characters.
Reminder windows are sometimes not redrawn (left blank) when raised or
uncovered.
