I have a service that when shutdown requires a username and password. I use `read` in my script to gather this info because I can't have it in the file. When I run the init script by hand it will ask for the username and password and everything shutsdown properly. When I run reboot or halt I get no prompt. get user input in a shutdown process?
View 2 RepliesI'm trying to make a script that loads at boot and asks for user input before doing it's stuff. So I created a script in /etc/init.d/ following the example given there (skeleton file) and used update-rc.d to make it load before GDM.
But when my script requests user input, init doesn't stop, and goes on loading other services and loads GDM. I have to CTRL+F1 to get to my script. I want my script to pause the init system till it ends doing it's stuff and the the other services can go on loading.
I tried
#X-interactive: true to no avail.
I'm working to make guest OS run as no privileged user. I've found a script made by an Italian guy that should start the guest instance during boot. Unfortunately the script was made for Debian and as I'm not confident with bash, I'm having some difficulties in making it work under RedHat 5.3 launched as root
vbox-ithaca start
vbox-ithaca: line 116: log_daemon_msg: command not found
sudo: VBoxManage startvm ithaca --type vrdp: command not found
vbox-ithaca: line 119: log_end_msg: command not found
these errors to me basically say that those commands aren't in PATH, but I couldn't find them anywhere

View 3 Replies View RelatedIm having a bit of a problem with a init script which I wrote to start and stop oracle listener and database. My system is Redhat 5.4 64bit and oracle 10g2 standard database (64). I have created the script and added the script using
chkconfig add orashut, and on the script by chkconfig level 345 orashut on Now I can use service orashut start, stop, restart, and works fine and when the system comes up the database and the listener would come up as planed. But the problem is when I do a reboot or shut down the db or the listener would not shutdown as expected, I placed at K00 values as well in rc0.d and rc6.d to give the priority at the shutdown. Even though all the configurations say this script should run before everything else at the shutdown time this is not working.
When I bring down a certain machine with some nfs mounts using init 0, it hangs forever while trying to bring down the mounts, but if I bring it down using halt -p (which I've read just calls shutdown if I'm in init 3), it comes down in a timely manner. I've also read that shutdown still calls all the rc.d kill scripts just like init 0, so what is actually the difference between them? Is it this:
Quote:
All processes are first notified that the system is going down by the signal SIGTERM?Does init not do that? I'm not trying to directly troubleshoot why NFS makes me hang with init 0 at this point, just wondering why shutdown works whereas init 0 doesn't.

I try to shutdown a box running Fedora (fc12, all updates applied) remotely. From various threats I selected the following way that suits best to my needs: I edited the entry for shutdown in /etc/passwd:
shutdown:x:6:0:shutdown:/sbin:/usr/bin/sudo /sbin/shutdown -h +1
Logging in from a tty with shutdown gives the desired result: The computer does the shutdown. Then I tried the same using sshd and plink:
plink -t -l shutdown -pw xxx 10.0.0.123
As a result I get:
Using username "shutdown".
Access denied

I wrote a custom init script for a java application. The script resides in /etc/init.d and follows the convention for the init.d scripts. However, the script runs the java process as root. I need these processes to run as a non-root user. Is there a way besides using sudo or su in the script (seems inelegant), to run the script as a specific non-root user? Perhaps using a .conf file in /etc/init or a daemon wrapper? What would the Ubuntu way of doing this be?

I capture 5-6 images into ~/screenshots. They are labeled Picture 1.png, Picture 2.png, etc. I would like to be able to rename them as Lesson 1.png, Lesson 2.png, and so forth. It works if I hardcode the new NAME (Lesson) into the script, but I want to replace NAME with a variable that I can input at a prompt or pass into the script from another. I have tried setting a variable and replacing "Lesson" with $variable in line #11, but that leaves me with only the extension and no filename.
I have also tried using $1 on the command line:

I've written a bash script that allows a user to input a directory location to find out the size of the directory. However, if the user inputs a directory and finds its size then inputs another directory then wants to quit, the script asks the user numerous times if he wants to quit!! The script won't exit until the number of times the user looks at a directory is reached! What gives?
Here's the script:

I have a script in which it searches the password file for a username based on the user's input. Is there a way I can take the bad input and keep it in a variable. (one that keeps adding all the non-existent users)so how would I get non-existent users into another variable?
View 9 Replies View RelatedWrite a program that requires the user to input the name of a file as an argument. If the user fails to include one argument it should make use of a thread that handles a signal. The signal handler should tells the user Incorrect number of arguments and then calls the terminate signal on the process.
If the numbers of arguments are correct then the program should allocate memory space to the file (5MB) and create a child process that requests the user for a character that it should send to the parent. The child should keep request for data until the user keys in the character O. During each request it should pause for 10 seconds, send the character to the parent and then requesting again for another character.
The parent should get the character from the child. Do not make the parent wait for the child to finish requesting for data. Make use of pipes to facilitate communication between the parent and the child. A second child should be created to read and display data from the file. Make use of any appropriate Inter Process Communication technique to ensure that the second child and the parent do not access the file simultaneously (Mutual exclusion).
I've been using python/bash to help myself automate things for a long time, however I am curious. One reason I use python more is because I don't quite know how to work with user input in Bash, such as getting it to ask for input and wait, and then placing that user input into a command.
Here's an example of a script I use from time to time for converting OGG video files into AVI.

It seems little weird that I can shutdown my system (as non root user) from GUI but now from command line. I understand this may have to do with old unix tradition. I am now writing a script to shutdown systems after a certain period of inactivity. How do i shutdown system as non root users and without using sudo? Also the shutdown option in GUI must be calling a command line internally. Which is that option? Can I use that to shutdown system as non root user?

If I have an array which its size is based on the user input, from some material, I need to use malloc function to allocate memory for that array what is known dynamic array. Don't forget to free it.hat's fine, however, I like to try things out even I know the program will crash.I have written some test program on my Mac using C language like this:int width = 0;//get user input, and assign the input value to width, for example, 3char * array_var[width];and width is an int, its value will be assigned by the user input. The point is, this program work as expected, for example, in command line, I input 3, then array_var length is 3, its size is 3 * sizeof(char *).
View 1 Replies View RelatedI have a script im having some problems with, what I need is to have the system generate a random password for me and use that password when creating new users to it.
System is Debian Lenny and script is in bash.
The program is znc. I have made it so that it will generate the random password on the shell but the problem is to use it in the bnc software.
To make a password there the command is znc --makepass and look like this:
My question is now if it would be possible to put in the script so it would "answer" when it need those passwords ? the random password that is generated is in a variable called $setpass and is NOT crypted.
Or is there any other software that would be able to generate that md5 string for me ?
I've been dual booting 10.10 with Windows7 for about a month. Today is the first time I've encountered a serious problem.
This morning, nothing functioned properly after trying to open several programs. The computer seemed to be "frozen", although the mouse was working fine.
I decided to reboot, but then encountered an even bigger problem.
It failed to boot and got this message: no init found. try passing init= bootarg
The problem now is that it requires a Live CD session and I keep getting this: GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0)
In case it matters, I didn't install 10.10 from an ISO, I just upgraded from 10.04.
My normal day to day user can't shutdown, restart, logout, etc...It just doesn't do anything at all when I try. This wasn't the case three days ago, just fresh installed and seeing the same problem (so it must be some setting saved in my home folder which wasn't wiped).
