Question Understanding shutdown
Hi there,
I start using the function shutdown instead of reboot + poweroff.
But there are some points that are not explained in the man pages.

1) What is the usage of the t swith.
Quote:
shutdown 22:30 'Beware!'
shutdown -t 30 22:30 'Beware!'
Both commands will display the message immediatly on every terminal and shutdown at 22:30. Where is the difference?

2) Can I specify the date/time like in the date command?
Quote:
supernova:~# date
Mon Feb 16 22:33:45 CET 2009
supernova:~# date -d 'now + 1 minute'
Mon Feb 16 22:34:49 CET 2009
supernova:~# shutdown 'now + 1 minute'
Usage: shutdown [-akrhHPfnc] [-t secs] time [warning message]
[...]
supernova:~#
Thanks for your help
Santiago

mdbfontsize

mdbFontSize(5)							 The m17n Library						    mdbFontSize(5)

NAME

       mdbFontSize - Font Size

DESCRIPTION

       In some case, a font contains incorrect information about its size (typically in the case of a hacked TrueType font), which results in a
       bad text layout when such a font is used in combination with the other fonts. To overcome this problem, the m17n library loads information
       about font-size adjustment from the m17n database by the tags <font, resize>. The data is loaded as a plist of this format.

       FONT-SIZE-ADJUSTMENT ::= PER-FONT *

       PER-FONT ::= '(' FONT-SPEC ADJUST-RATIO ')'

       FONT-SPEC ::=
	   '(' [ FOUNDRY FAMILY
	      [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
	    REGISTRY ')'

       ADJUST-RATIO ::= INTEGER

       FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font.
       See m17nFont for the meaning of each property.

       ADJUST-RATIO is an integer number specifying by percentage how much the font-size must be adjusted. For instance, this PER-FONT:

	   ((devanagari-cdac) 150)

       instructs the font handler of the m17n library to open a font of 1.5 times bigger than a requested size on opening a font whose registry is
       'devanagari-cdac'.
