Sorta. I use perl (this is badly hacked) and use the linux_logo
program since I'm lazy and don't want to parse uptime. =) This is
it:
--------------------------------------------------------------------------
#!/usr/bin/perl
$home = $ENV{"HOME"};
# get current uptime
$uptime = `linux_logo -g -a -F "#U"`;
@uptime = split(/Uptime /,$uptime);
@disp = split(/minute/,$uptime[1]);
$disp = "Current Linux uptime: $disp[0]minutes.";
if ($#ARGV lt 0 or $#ARGV gt 1) {
print "Usage: $^X sigfile\n";
exit(1);
}
open (SIG, "$ARGV[0]") or die "Can't open $ARGV[0]";
while (<SIG>) {
$sig .= $_;
}
print "$sig\n\n$disp\n";
#open (SIG,">$home/.sig");
#print SIG "-- \n$sig\n\n$disp";
#close SIG;
exit(0);
--------------------------------------------------------------------------
Like I said, it's pretty ugly. But it works.

Hmmm... Any general Linux book would have some decent bash stuff in
there. Can't think of a good one off the top of my head.
