General :: Check If Process Is Running / If Not / Execute Another Script
Jul 11, 2011
I have a game server running using java, and it tends to crash sometimes, and only way to start it now is manually, so i thought i could create a script to check periodically if java is running, and if it isn't, run my startup script for the game server also, if it's possible it should log when it actually started the server startup script into a text file or something, so i can check why it crashed.
I am using Sphinx search on my webserver and it quits after a certain amount of time leaving my search page broken.Here is a bash script that I want to run every 10mins via cron:
I have a computation going which takes a long, but uncertain, amount of time. I have another computation which needs to be run, but _after_ the first one is done. I won't be at the computer at that time to manually start the new process. I've done some Googling, and I found how to delay execution by a specific amount of time (e.g. "start process x in exactly 8 minutes from now), but that isn't quite what I want to do. Essentially, I'd like to tell the shell, "When process #nnnn finishes running, then start process x". Is there a way to do this?
I have an ubuntu 10.10 server and want to run a script on it to check if a process is running. If it is not running, it will start the process and also write into a log file.
When running the script i get the following error message:
I am trying to get a process ( SARG access log report tool ) to run every 10 minutes but I cannot get it to work. Here is the content of the crontab file ______________________________ SHELL=/bin/sh PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin # m h dom mon dow user command
Means I want to execute two executables one by one at the same time as shown below:execute1 execute2these are two executables. but the second one is executed after 1st one is closed is there any way two execute both.One way isgnome-terminal -e execute1execute2but here i want to hide the terminal window..........
I have a program(that is written by me) which need super user permission to execute it. But I need to let the normal users to execute it without using 'sudo ./executable' and just './executable'. how i can set the program to execute by the normal users without using 'sudo' or password prompting.
I add a user in my linux machine using the command 'useradd' as shown below. # /usr/sbin/useradd -c "Non Root User" -d "/home/testUser" -g root testUser "/etc/passwd" file shows that user created with uid '517'
I have an Ubuntu server in which a file is dumped every hour and a new file for the next hour and the process continues. If there is any problem due to which the creation of file stops then empty files are created every minute till the process is killed & started again. I need help to make a shell script to check if the empty files are being created and then kill the process and start it again.It would be a great help if anyone can help me regarding this.
My question is how to check whether this script is running or not (It can be checked every 10 minutes) and how to make it as a service. (I don't have root access to put this in rc.local file or somewhere else).
How do i check if NFS mounts are still up and running?
when i do the command MOUNT , i get some result, but how can i see (or check) if they still up and running? I'm not so familiar with this command, so i hope that someone can guide me
I know that there must be some NFS links mounted, so if one fails, i need to see that with like an echo or something.
so I wrote a small script that pretty much just takes in two numbers and counts from the first to the second, e.g.
unknown-hacker|544> count.sh 1 3 1 2 3
My problem is I want to make it so that if you input invalid parameters, such as non-numerical characters, more than 2 numbers, etc., you'd get an error message
I have a bash script that messages the user periodically. Is there any way in the script to check if the screensaver is running, so the script doesn't spam messages while the user is away? The xscreensaver process is always running in the background, I've noticed.
i've some trouble to write a script on java on linux to check if service(ie:smbd) is runing or not,, could you give me some example? Or if is there any source about it for me to learn? i've two days search with zero result...
Is it possible, using ps, to determine where a process is running from? I have two applications, both are identical and running in parallel directories, such as /app1/start.sh and /app2/start.sh. If I run ps -ef then I'm unable to tell the difference between the two
Using ps (or alternative), how can I tell that PID 123 belongs to app1?
How can i get the notification of process which are currently running?
We wrote one script which is being fired for every minute, instead of that is there any to trigger the event from linux core implicitly if there is any change in my process(pid)?
I have Linux server with cent OS.I have installed tomacat6.0 and postgresSQL8.3 on it.The thing is i wanna know whether the tomcat and postgresSQL is running or not using the script.
How do you move a running process to the background? For example, type the command sleep 60 on the command line and try moving that process to the background.
Can anyone tell me that how to get information about stack, allocated by kernel to a running process? for this ,is there any api function,any system call is available in ubuntu 8.04 ?
