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.
View 5 Repliesso 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
How can I check which version of bash I'm running
View 2 Replies View RelatedI 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:
Code:
#!/bin/bash
if pgrep searchd | grep "[0-9]"
[code]...
I'm having trouble trying to make a script. What I want to do is check if xScreenSaver is running in my user account. If not, run it. If it's running, kill it.
So this is the script I've made:
Code:
The problem is that I've echoed the output of $(pgrep -u $(whoami) xscreensaver) and it always seems to add 4 numbers to the pid, even if the pid doesn't exist. What do I mean by "doesn't exist"? That no xscreensaver is running in my user, and if I run pgrep -u $(whoami) xscreensaver in bash, I get not output, but if I run the command though the script, I get (for instance) 4050. If I run it again, I get 4054, and again 4058... etc. What the hell is going on with that?
<edit>never mind dump the ;'s and it all works fine</edit> I'm trying to write a bash script that will check if XMBC is running if it is then do nothing else start it then do some other things.This is the start
Code:
#!/bin/bash
DISPLAY=:0.0

I apologize if this is the wrong place to ask, or if this has been asked before, but it has been bugging me for some time and I have not had any luck with it. I imagine that my problem is not unique to my circumstances, but here goes.I am running Arch Linux, and quite frequently watch videos, particularly flash, in fullscreen. However, eventually, the screensaver appears, and starts dimming the screen. I have the screensaver set to run whenever the computer is 'idle'. Does anyone know a way to either.Stop the screensaver from appearing when in a flash video or watching other video?Stop the screensaver from appearing when a flash video or normal video is full-screened? Heck, even..Let the screensaver know that my machine is not idle when watching flash.

I presume there is something in the JWM window manager - or Puppy Linux Lupu 5.01 itself that is conflicting with the normal loading of GMPLAYER....
I would like to know how to troubleshoot, and fix this problem if possible (even a workaround would be great).
I know that $1 ... $n will set the argument to the values but what happened if I have many options in one scripts lets suppose.
I can run:
myscript -1stargument -2ndargument -3rdargument
or myscript -1stargument
or myscript -1stargument -3rdargument
In my scripts I have
if [ $1 = "-1stargument" -o $2 = "-2ndargument"] #for every instruction I need
fi
but is there any way to do:
if [ (any arguments or commands) = "(mydesired option ] ; then
(do this...)
fi
i tried to create a if else statements or either an else statement I get a message saying that the directory exists (mkdir: cannot create directory `./MAY2010': File exists I am running this in a crontab file and I dont want any output telling me that the directory exists. I just want to check if the directory doesnt exist, create one else do nothing (not even a message telling me that the directory exists).

View 10 Replies View RelatedI have been using linux for a bit of time but would still class myself as a noobie. I dont know excatly what I am looking for but I can best describe it in a sanario. I have started creating bash scripts which are looped indefinetly which checks afor files to process. my problem is, is there any way to check if the file is complete, as if the file is large and is being coppied from a different volume the file may still be copying or if the file is being uploaded by a user over samba/nfs, and if the file is still copying the process will most likely fail.

View 4 Replies View RelatedI'm trying to write a script where I want to check if any of the parameters passed to a bash script match a string. The way I have it setup right now is if [ "$3" != "-disCopperBld" -a "$4" != "-disCopperBld" -a "$5" != "-disCopperBld" -a "$6" != "-disCopperBld"]but there might be a large number of parameters, so I was wondering if there is a better way to do this?EDIT:I tried this chunk of code out, and called the script with the option, -disableVenusBld, but it still prints out "Starting build". Am I doing something wrong?

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.

View 5 Replies View RelatedI 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.

Is there an easy way to lock my computer screen without a screensaver running? What I'm trying to do is basically fire up a web browser or terminal window that I want to watch/monitor but lock my screen so that it can't be changed unless you know the password to log in as that user.
View 9 Replies View RelatedI have upgraded to 11.04 all seems well except that now the two machines I have upgraded frequently hang while the screensaver is running. (with unity desktop).
