General :: Execute A Command Every Time A "folder Changes Status"?
Jun 4, 2010
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 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?
I was created one folder in linux with current time was 1978(For example). I was moved this folder to usb(FAT32 file format).While seeing this folder in window its not showing the folder time created time stamp, because the USB file system only support the year after 1980 . But again i am putting the same folder in linux ,its showing the correct time stamp.How is it possible? Because FAT32 only supports timestamp after 1980, but still its showing 1978 in linux system
Is there a way to execute some command and then after the command completes utomatically reboot the system and then after the system reboots execute another command ? For example look at the sequence shown below(1) Execute command-1(2) After the command-1 in (1) is completed,reboot the system (3) Execute command-2(4) After execution of command-2 reboot the sytemIs there a way i can automate this process so that i need not reboot the system manually
I have a script which builds a project and then runs junit tests. However, if the build fails, the junit tests fail with the same error message.Therefore the command which runs the junit tests should only be executed if the build was successful.
I have a folderA that contains folderB that contains a lot of files. I would like to get rid of folderB, but not its contents. I want those contents to be inside of folderA. How can I accomplish this on the commandline?
I would like to know if it's possible to create a continual log for a network interface card's status. That is whether it's up or down and time and date stamped if possible.I'm wondering if there is a cli command that exists to do this I've looked at "ethtool" but this only sets the parameters of the nic.Also looked at the log files that I could find /dev/log var/log, but there is no mention of a status for eth0.
I want a quick and simple way to execute a command whenever a file changes. I want something very simple, something I will leave running on a terminal and close it whenever I'm finished working with that file. Currently, I'm using this: while read; do ./myfile.py ; done And then I need to go to that terminal and press Enter, whenever I save that file on my editor. What I want is something like this: while sleep_until_file_has_changed myfile.py ; do ./myfile.py ; done
Or any other solution as easy as that. BTW: I'm using Vim, and I know I can add an autocommand to run something on BufWrite, but this is not the kind of solution I want now. Update: I want something simple, discardable if possible. What's more, I want something to run in a terminal because I want to see the program output (I want to see error messages).
How do I set up SSH so I don't have to type my password? i execute the following command ssh -l admin hostname command but each time i execute it, it ask me to enter password.how i can give it password as default because i'm going to put in bash file ?
I am working in a CentOS environment with numerous CentOS machines. Currently there are multiple developers that each have their own login/home directory and then for various admin tasks we all share a single super user account.
The problem
I have a number of aliases, variables, functions, and settings that exist in my personal login's .bash_profile. None of these are available in the shared super user's .bash_profile. My current work around is that everytime I sudo in as the super user and I re-execute my .bash_profile from my personal user's home directory. I am not allowed to edit the init stuff for the super user
The Question
Is there any way I can automate my sudo sequence such that it will execute my personal .bash_profile after I've executed sudo without requiring me to edit the super user's bash init stuff?
sub init() { $Test->description("Establishing the connection to the client"); eval { $Host = host($CLIENT) or die($@); $Conn = connect("#ssh") or die "Client connection Failed" . $@; }; if ($@) { $Log->error("Unable to instantiate the Objects for the Test" . [Code]...
Here I'm trying to connect windows machine using connect object which is working fine. But when I tried to execute the command on Windows machine from Linux machine by using:
I am having trouble getting the while loop to execute in the ssh command:ssh $USERID@serverX "while read line do echo $line done<$list_dir/cost_feed.lst.old"Error:bash: -c: line 1: syntax error: unexpected end of fileI have managed to use simpler commands with ssh like:ssh $USERID@serverX "pwd; cp x y"I expect that I need to add some combination of escape characters or semicolons
My laptop has a dead battery. Even when it's fully charged, if the power cable is pulled out it only lasts for about 4 minutes before it dies. I'm running Ubuntu Lucid Lynx 32-Bit. What I want to do is create some sort of script or program that will immediately set my computer to go into hibernation once it detects that the power cable has gone dead. I'm willing to look into all ways of doing this. I can program in C, but I'm not familiar with the API used to manage Power Management in Linux.
On my ubuntu I have a command pm-suspend, which puts the computer to sleep. It has to be run with sudo. Since it is inconvenient to be forced to type the password every time I want my computer to sleep, I thought maybe there's a way around it. Naively I thought that if I'd create a script as root, that invokes pm-suspend, and then let anyone execute that script, I could run that script as my own user and then that script would be considered run by root and hence be allowed to run pm-suspend. Obviously that didn't work. The root-check procedure in pm-suspend still found out that the original executor was someone different from root.
Still I think something similar (although slightly more elaborate) should work.I'm thinking about the process that allows the user to mount hard drives for example. Normally root is required, but it is somehow bypassed by the gnome utility mounting.
How can I give execute permission to chmod command from run level 3.Because in GUI mode we have the execute option in the properties of file. E.g. I gave following command chmod -x chomod After that I want to give the execute permission (x) to chmod command again but how from command prompt?
within my bobje directory, I have many directories and some log files . I want to delete those log files without traversing the subdirectories. so i performed these commands and getting the mentioned errors.
Is possible (by root of course) to run a command from console, that will be executed on X-session owned by another user on the same linux box/machine ? Example: Can root open xclock for another local user logged into X11 ?
So I am trying to put together a simple command that when executed from the project folder will run the appropriate hg/svn command in each project i.e:
[Code]...
Since the client has many such projects, Instead I am looking for a solution similar to find -exec where the svn/hg commands are automatically executed on each first level of match (i.e. svn up is run in the project/a folder but not in project/a/subfolder). How can such a command be constructed ?.
