I want to record an internet radio station starting at 2:00am tomorrow morning. The specific program on the radio station lasts until 6:00am. The command I need to run to record the station is: Code:mplayer http://wjcu.jcu.edu:8001/listen.pls -ao pcm:file=indie_heat_of_the_night.wav -vc dummy -vo nullI'd use cron, but 1. I'm not sure how to and 2. it seems unnecessarily complicated for something that I only want to run once. If cron is the only/easiest solution, I guess I'll just have to resort to that, but I'd rather not.
View 12 Replies View RelatedI've been given one of these ubiquitous usb-sleep buttons which is basically a supersimple usb-keyboard. It's a big button that sends a SLEEP keypress to the computer when you slam it. But that is pretty boring. I'd love to remap it to do something more fun but I can't figure out how to bind to only the sleep press from the button and not from my ordinary keyboard.
The button identifies as
Bus 001 Device 035: ID 1130:600d Tenx Technology, Inc.
I'd like to know if there's either
a way of mapping a key from a specific keyboard to an action OR a way of remapping the sleep key from a specific keyboard to a new key-code or something like that.

I am trying to find a way to execute a python script in regular time intervals? How can I do it?
View 2 Replies View RelatedI need a script that executes a command based on a folder's last modified time.
if "/var/data" was modified in less than an hour then "/usr/local/etc/searchd stop" should be run
can we use "find -mmin +60 -type d" in conjunction with second command
We have configured a script to be run at specific time using crontab.
Code:
# crontab -l
as per the crontab entry script should run every day 11.15 a.m
Every time when the script is executed i get a mail but when i run it using crontab it doesn't send any mail.
However when i execute it manually i get the mails.
Even the execution is getting logged in cron log.

View 5 Replies View RelatedI'm trying to allow a specific group on my machine to execute one command with sudo without requiring a password, so what I want to do is add something like this to sudoers:
%groupName ALL = (ALL) NOPASSWD: /bin/bash /path/to/shfile.sh argument1 argument2
argument1 needs to be a url : http://subdomain1.subdomain2.domain.com
argument2 needs to be a path of the form /var/www/demo/SomeFolder/application/config/config.php
How do I put in a regex form that sudoers will understand ? I tried reading the sudoers manual, but it didn't help a lot .
is there any way to execute a command every time a "folder changes status"? Under windows there's an API which pro-actively tells you when something has changed within a directory, so I was trying to achieve something similar under Linux. I can't think anything else other than check the list of files and parameters (e.g. date/size/owner) every few seconds, but that's not ideal of course... So what I'm asking here is: is there is a way to set linux to tell me rather than me go and check?

I am running Centos 5.3. I ran no updates, performed no installs, nor changed any configuration immediately prior to this issue. My problem is this: when I run the command startx (default runlevel 3), it is a long time (5-10 minutes) before Gnome startx, and once it does start applications will not run. Also, when I try to use sudo (from any environment, even ssh), it is a long time (5-10) before the command is executed.
I cannot say for sure, but it seems like this is an intermittent problem. Sometimes X takes a long time to start, but once it starts it will launch programs. Sometimes X takes a long time to launch, but once it starts it will only launch certain programs. Though presently X always takes a long time to start, and I cannot successfully launch any programs.
A while back a had a similar problem to this (x taking long time to start, sudo taking long time to execute) and it ended up being a DNS problem. Unfortunately, I cannot remember exactly what it was and I stupidly did not document it. Maybe this is also DNS related, I don't know.
I don't know what log files to look at for problems with X, Gnome, and sudo taking a long time to start.
way to hibernate at a specific time or after a some minutes (like 40 minutes to an hour, guess the exact time doesnt matter anyway). normally i shutdown my comp at night with
Code:
sudo shutdown - P HH:MM
which works just fine, but sometimes i have like 4 workspaces of stuff open that i'm working on so i'd rather just hibernate. shutdown -H does this halt thing that is really not my cup of tea so from the aformentioned googling i found out about at and sleep and crontab etc. but at and sleep cant recieve my sudo password beforehand so its useless and crontab is for repetitive scheduling, which i'd like to avoid cause i would hate to be working and suddenly have my forgotten crontab script hibernate me.
so is there any way to do a delayed hibernation? or at least some way to provide the sudo password to an at or sleep prefixed command, beforehand?
i'm only interested in doing it straight up through the terminal, not through other 3rd party software cause i tried a few of those before i found out about shutdown and they didnt work very well.
I use two monitors,my problem is that I want to change the setup,so that the other monitor becomes default.There's no problem with my BIOS settings and I have tried every GUI tool that could help me(to my knowledge).Well I've found this URL...that helps a lot but I want to execute the command every time I boot before the splash screen(so that the login screen appears on the right monitor).I've tried rc.local but had no success.Any ideas on how to execute the command at boot time?

this is the example i found online Code: #crontab -e -u root Code: 0 20 * * * /sbin/shutdown -h now since the above turns it down at 8pm i need to edit it to 5 30pm
Code: 0 17:30 * * * /sbin/shutdown -h now would this be correct?
Can anyone shed some light in this? Using Fedora 14-64, new install, 185 Opteron x 2 gig ram, sata hard drives formatted Ext4.However, in my home directory I have a folder for all my digital photos of which I have more than 20,000, and in another folder I have images and clipart of which I have almost 8,000. That is a lot of read only access to a significant number of files in my home directory.
How can I tell Fedora to not update the LAST ACCESS TIME of those files (specifically images) that will never actually be changed other than just being read. I want to leave that feature enabled for the rest of my home directory. I am trying t; improve my disk performance in Nautilus because whenever I access the folders with my images the system literally slows to a crawl and sometimes even the mouse stops working for several minutes until Nautilus has finished having its heart attack.
I am using openSUSE 11.2 and had the same issue once before in openSUSE 11.1 After some time, two domains I use very often can't be accessed any more, these are: Google and [URL]... (am doing some OO development recently). At the time where I write this post, only these two are "blocked".
When I try to access these two domains using Firefox, w3m or telnet, it tries to open the connection forever. Ping works fine. I tried opening the IP directly in the browser, but same problem, the connection never reaches. I know it's not a router issue, as the other computers can access these domains. Still, I tried to restart the router, but the issue persists. I tried restarting the network service (/etc/init.d/network stop + start), also nscd, without success. The only way I found to make it work again is to reboot. This problem reappears from time to time, after using the computer for a long time, and accessing these domains a lot of times. Note that I also use suspend to disk, so the "blocked" state is kept after resume. Only reboot "cures" it.
How do you find a file modified March 17, 2010, between 3:30 pm and 4:05 pm? I know that I must be missing something somewhere.How do you search for info like this? I goggled "search files time Linux" and got about 38,300,000 results. I looked through the first four pages and did not see what I was looking for.Do I need to calculate how many minutes ago that is and give that to find.I really want to do this in the GUI so that I can operate on the files found without typing in so much stuff.

View 4 Replies View RelatedI'm running Ubuntu 10.10 in a computer with a 7200rpm HD, 8Gb Ram, and a Core i7, and the time it takes to load the desktop is insane. There are threads that mention the problem of gnome looking for nonexistent floppy drives and to solve the problem by disabling that in the BIOS (option I don't have). Anyway, besides that problem, by running at startup a gnome-terminal with the iotop command, I noticed that two processes have a huge i/o load on the system: google desktop and ubuntu one. I would like those programs to run as part of the startup process, but be launched after several seconds (to allow the rest of the programs to load). Is there any way I can achieve this? I think there should be a way modifying the commands under startup application, but I cannot find anything that works.

How do I get vlc to start at a specific time in a media file. I can do it easily in mplayer2, mpv but not vlc. Let's say the media file is named abc.avi (file format,container not important for this example.) Also the running time is around 2+ hrs. In mplayer2 and mpv I can simply do :-
Code: Select all$mpv abc.avi --start=00:59:00
And it will start running at that point in time.
In vlc, it also seems to have something at :-
Code: Select all[$] vlc --advanced --help
......
......
Playback control:
--input-repeat <integer [-2147483648 .. 2147483647]>
Input repetitions
--start-time <float> Start time
Now I don't understand what the <float> bit. I tried :-
Code: Select all$vlc abc.avi --start-time=00:59:00
But that didn't work. It's possible that it might be a bug, then again I might not have done it correctly.
I have looked high and low for this, but to no avail. I am looking for a script to shutdown my computer when it reaches a specific time (say 10:00). I know about the shutdown command but if I use that I cannot shutdown my computer manually. I would like to be able to shutdown manually AND automatically.

They are only set to do security updates unattended, but what I am wondering is if there is a way to change the time that they install? I want the updates to install early in the morning, at like 3am or such, so I can reboot the machine when I get up if needs a reboot.I found a few mentions about it, but nothing specifically talking about the time.[URL]..

I am trying to extract just a few files/folders from a Time Machine backup, but can't seem to find them. The drive is automatically mounted in Ubuntu, and am able to access after enabling view hidden files, the HFS+ Private Data Directory. But that is a jumbled array of thousands of numbered folders, with each taking a fair amount of time to open on this aging Dell running 10.10.
I've tried running the standard Places - Search for Documents, with 'Show hidden and backup files' enabled, but that won't pull up any of the search times I'm going for (and seemingly won't find anything at all on the drive). So, is there any way to decipher the directory tree so as to be able to access this data from Ubuntu? Or perhaps a file embedded somewhere in there that lists out the original structure, so that I can use it as an index to see what number correlates to what originally named folder?
