What is the exact way 'reboot -f' command operates? How does it differ from regular reboot/shutdown? Is it proper to restart pc using 'reboot -f', if not why? The reason why I'm asking this: After installing live-distros via USB, I usually do this 'reboot -f' for restarting.

View 1 Replies View RelatedI would like to know if I can reboot my headless ubuntu machine from command line to a different OS on the same disk. To clarify, I want to do this without having to manually choose in GRUB.
OS1: Ubuntu on sda1- it is the default OS in an always on server.
OS2: Fedora on sda2 - have to login into this once in a while.
There are no monitors attached with the machine. So I cannot manually scroll through grub and choose Fedora. I want to know if there is a command I can issue remotely to the Ubuntu server to reboot to Fedora.

I've added entries to my Openbox menu labeled Reboot and Shutdown. Problem is, reboot and shutdown h only work as root, and I never login as root. I've tried su-to-root -c reboot, but the menu entries remain unresponsive. I do not have sudo installed because I feel it is a security issue. However, I found that sudo reboot works with the menu entry, but only if my account is set to use sudo without a password in /etc/sudoers. I use tint2 as my panel, but have had no luck with finding a shutdown/reboot button.

I created a script myshutdown.sh in /etc/init.d/ to shutdown rTorrent if the reboot or shutdown now -h command was executed.
#!/bin/bash
#rTorrent Shutdown Script
echo "Shutting down rTorrent!"
kill -2 `pidof rtorrent`
I set the file as executable.
sudo chmod +x /etc/init.d/myshutdown.sh
I inserted a symlink in the rc0.d directory with the process order K04.
sudo ln -s /etc/init.d/myshutdown.sh /etc/rc0.d/K04myshutdown.sh
I also inserted a symlink in the rc6.d directory with the process order K04.
sudo ln -s /etc/init.d/myshutdown.sh /etc/rc6.d/K04myshutdown.sh
Apparently rc0.d is for shutdown and rc6.d if for reboot
After reboot it appears that rtorrent does not run (I cannot connect to rtorrent via rutorrent) but really what is going on. I am trying to do this because rtorrent does a hash check on all files if it is not shutdown properly. I just want it to shutdown automatically and safely, before the system shuts down.
I am using Slackware 13.1 on my Asus K40IN, I also use dual boot by LILO with Windows XP. In Windows XP I can reboot or shutdown by select Start -> Turn off Computer, or just physically push the power button, then the machine will shutdown. In my Slackware 13.1, I can physically push the power button, the machine show that it is switching to run level 0, and then it will power off. However, I can not turn it off or restart my machine by the command (run "halt" or "reboot" as root), it show identical things like when I physically push button, but when it turn to status "Restarting machine" or "Turning off machine", my computer hang there, it does not power off machine or restart it. Is there any one experienced this situation? What should I do to fix it?
View 3 Replies View RelatedI've upgraded a server on our LAN from fully functioning Wheezy to Jessie. All seems fine except remote administering using Putty from my windows workstation when issuing reboot from command line, it goes down and reboots but stops at login prompt asking for username and password and does not come back on the LAN network. This server does not normally have a monitor or keyboard so my ability to remote admin this server in effect is disabled.
If I log on, it will come back on the LAN network. I've checked the logs but can't see any errors. Is it in the configuration of Jessie somewhere or perhaps a Grub issue. I have 5 other production Wheezy servers that I intend to update to Jessie once I understand how to deal with this problem.
last week while I was using ssh to the computer1 inside a NAT as usual, I made another tunnel from the computer1 that I was connecting to, to another computer2 inside that NAT (ssh 192.168.1.130) and after making some changes in computer2 I typed reboot. The computer2 rebooted but the tunnel totally hung and I had to kill it in my laptop. Since that day I haven't been able to ssh to the computer1 as I am used to.

View 4 Replies View RelatedFurther to this LQ thread which Tinkster solved by suggesting the last command (thanks Tinkster) I have been exploring last -x reboot and have found that the reported duration is incorrect for the last reboot and shutdown when a old wtmp file is used. Not having a record for the following shutdown, last assumes that the system has been up until the current time and similarly for the shutdown.
The output comes in time order, latest first, each line showing the time of the reboot and the uptime from then to shutdown. Using last -x reboot shutdown to show the shutdown time, here's an illustration
Code:
shutdown system down 2.6.29.6-smp Sun Mar 7 15:35 - 03:02 (11:27)
reboot system boot 2.6.29.6-smp Sun Mar 7 09:35 (05:59)
09:35 until 15:35 is 05:59.
When the uptime exceeds 24 hours it is shown as (<days>+<hours:minutes) like this
Code:
shutdown system down 2.6.29.6-smp Sun Feb 21 12:39 - 13:20 (00:40)
reboot system boot 2.6.29.6-smp Sat Feb 20 09:39 (1+02:59)
09:39 until 12:39 the next day is 1 day 02:59.
The time in parentheses at the end of the shutdown lines is normally the time until the next shutdown.
So far so good. The incorrect output is for the last reboot and shutdown of an old wtmp file. Here's the output of last /var/log/wtmp -x reboot shutdown; last -f /var/log/wtmp.1 -x reboot shutdown
Code:
[snip]
reboot system boot 2.6.29.6-smp Fri Mar 12 07:42 (01:54)
shutdown system down 2.6.29.6-smp Fri Mar 12 01:31 - 09:37 (08:05)
wtmp begins Thu Mar 11 08:25:26 2010
[snip]
reboot system boot 2.6.29.6-smp Wed Mar 10 14:12 (15+01:42)
shutdown system down 2.6.29.6-smp Wed Mar 10 12:41 - 15:54 (15+03:13)
[snip]
The boot started at "Wed Mar 10 14:12" which had an actual uptime of 1 day 11:20 is reported as 15 days 03:13 which is the time from then until the last -f /var/log/wtmp.1 -x reboot shutdown command was issued. The time from shutdown to shutdown is similarly affected.

View 1 Replies View RelatedBash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).
I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?
When you run the following cp command in the BASH terminal, how does Linux know which files are the source and which are the destination when copying multiple files from one location to another?How does Linux know that the services, motd, fstab, and hosts files are the source and the /home/fred/my_dir is the destination?This question came up in a Linux class and I was not sure of the answer. I was thinking it is based on the source path entered ending with a file path and the destination being a directory, but was not sure.

View 4 Replies View RelatedUp until now I've been using plink to remotely compile a project I'm working on. But recently the administrator from the remote server updated the distribution and messed up some configurations. My project has a lot of scripts written for tc shell (tcsh), and now the default shell is bash. There is no way to change this. Another problem is that now I need to run newgrp to change my default user group.
So... to work around this problem I've changed my .bashrc to run newgrp and then tcsh. If I do a normal connection using SSH, everything works as expected, but when using plink, or SSH to remotely execute commands, the shell gets stuck on the newgrp command. I think it's because both applications need a return value from newgrp to send the command I need to execute. Remotely running scripts that call a shell also get stuck like newgrp (newgrp also opens a new shell and that's why it gets stuck) my .bashrc is as follows:
Code:
user_grp=`id -g`
if [ $user_grp != 4919 ]; then
newgrp new_group_id
else
