General :: Uptime - Getting Date & Time Of System Startup?
Mar 28, 2011I know that uptime prints the time a machine has been up and running, but is there an easier (reliable) way to get the date of the start up than counting down from this output?I tried looking around /proc, but didn't find anything of relevance. There's also a line like this on my dmesg: [ 0.673492] rtc_cmos rtc_cmos: setting system clock to 2011-03-14 14:26:52 UTC (1300112812), but I'm wondering if this method is distribution and kernel version agnostic.

May 11, 2011My Linux system was last rebooted few hours ago. But it seems little confusing for me to figure out the exact reason behind it. I guess following command should justify what i meant to say.
Code:
# date
Wed May 11 13:22:49 IST 2011
# last | grep "May 10"
reboot system boot 2.6.18-194.el5 Tue May 10 17:35 (19:46)
root pts/1 XXXX Tue May 10 17:24 - 18:18 (00:53)
[Code]...
My question is Why the uptime is saying that the system is up since last 47 min.It should be more than 1 day if i m not wrong.

Programming :: Date Formatting From Stat Command?
Jul 23, 2010I'm writing a script that takes the date attribute of a file when it was created and appending it to the name. I'm pretty close to what I need, but the date appears in yyyy-mm-dd format and I want it to read mm-dd-yyyy. What I have done so far is something like
for ((i=1;i<=50;i++));
do fdate=`stat -c %y Video Snapshot $i.png|awk {'print$1'}`;
newname=Personname-$fdate-$i.png;
mv Video Snapshot $i.png $newname;
done
This works decently but the date comes out in the yyyy-mm-dd format. How do I change it?
General :: Pass Multiline Output Of A Command Into 'date -j'
Mar 3, 2011I am doing some NSCA log parsing and I want to get an output like this:
2011-Feb-18:11:00:07
2011-Feb-18:11:00:07
2011-Feb-18:11:00:07
2011-Feb-18:11:00:08

I have tried this, but it treats the entire output as a single line, then plops a timestamp on the end (I think):
Code:
sort -b -k4.9,4.12 -k4.5b,4.7Mb -k4.2,4.3 -k4.14,4 foo.log| date -j -f "%Y-%b-%d:%T" "+%s" "`awk -F '[ [/:]' '{print $7"-"$6"-"$5":"$8":"$9":"$10}'`"

Mar 26, 2010Example: In rc2.d I have S99test. In it: Code: #!/bin/sh mplayer -playlist "/music/Thom Yorke - The Eraser" Reboot; hear the loveliness; press pause (lirc setup)...still loveliness.
Login as root; "pkill mplay";hear nothing; "/etc/rc2.d/S99test"; more loveliness; press pause...silence! I know that i the former case, mplayer is assigned (for lack of a proper term) to a session, e.g. tty1. Not so in the latter. But why should a program like mplayer not receive (or ignore?) input from lircd, simply because it doesn't have a session? And how can I get mplayer (or any program run from boot scripts) to work with other programs (like lircd)?
