I want to get the time when program starts and finishes. But it always show the same time. Here is my shell script. But it always show that `START TIME` is same as `END TIME`.
Code:

host_list=("c15-0330-01.ad.mtu.edu" "c15-0330-02.ad.mtu.edu" "c15-0330-03.ad.mtu.edu" "c15-0330-04.ad.mtu.edu")
program=("L_1" "L_4" "L_3" "L_4")
subject="The job is finished"
START=$(date +"r")
address="/home/campus27/zwang10/Desktop/AWRR/program/power/vmodel_1/nprot/K_10"
ssh -f "${host_list[0]}" "cd '$address' && nohup Rscript '${program[0]}.R' > '${program[0]}_sh.txt';echo 'The job\n $address\n${program[0]} is finished\nSTART TIME = $START\n' END TIME =`date +"%r"` | mutt zwang10@mtu.edu -s '${host_list[0]} - Job ${program[0]}.R finished' -a '$address/${program[0]}_sh.txt';"

Looking for a program that can save my programs and preferences so that when i
do reinstall i don't have to individually configure each program with it's preferences.


much appreciated.

when a command is typed(i.e. /path/to/the/program), as a normal user, he should be able to run that command , execute that program as ROOT and log out root after the execution is completed.
Only one user should be able to do it.
Hence, I have created a new user vj and added the following command in visudo:
Code:

vj ALL=(ALL) NOPASSWD: /path/to/the/program

Now user vj will be able to typein the command.

What I need is that the program which is been called must run as if it is run by a root user,and when the program is completely executed, exit the root user.

How do I proceed?

Hi,
I am trying to write to usb flash drive using a C program. I have just created some files in USB device and doing my tasks using fopen,fread and fwrite on those files. I was just wondering what is the standard data rate that can be achieved using fwrite() on a file in usb. Secondly what is better way of transferring data to USB flash drive using C Program? Obviously I am a newbie

There is an option in encfs:

--extpass=program Use external program for password prompt

I want to use such program for this:

#!/bin/bash
zenity --entry --title="password dialog" --text="Enter your _password:" --hide-text

But how can I pass such obtained password to entfs call?

Any idea?

Hello everybody and thanks always for the help

I think the question I am about to ask is very beginners like, so I would appreciate the help.

I know (although I don't remember right now) there is a way to run a program on boot. I think it involves rc.local (correct me if I am wrong) I think you can put there the processes that you want to be run everytime linux is rebooted.

My question is, what should I do if I want a program to be run everytime some other event happen? For example (and in concrete) I am using a camera connected to my linux system and I want a program to run everytime I unplug and replug the camera through the USB port.

Can someone share his/her knowledge with me on this point

Thanks a thousand

i have researched this issue. it makes me feel like a noob. i some how messed up my dvd drive for a while with copy and paste terminal commands . eventually i had to reinstall. decided to donate and buy zorin os 9 ultimate. i've experimented with a couple distros like mint. i just can't seem to find a good program to play a dvd.

is there a way?

my drive now reads discs and it seems like something is there.

just did a test burn and that worked so the drive should be fine. it's a satellite c655

Hi ,
In my program, for a process A executing operation, there are multiple threads created.
One of the thread A checks whether process is active or not
Second thread B executes a function
One of the periodic thread C calls a callback function that executes an audit after every 30 secs.

In the audit , the function uses g_spawn_commmand_line_sync() function to spawn a child process that executes a command line (shell script).

Since g_spawn_commmand_line_sync() spawns a new child process .
In the error case scenario, the spawned child process got stuck and became zombie process. It did not get killed.Also it acquired sockets which were assigned to a thread B executing operation.

Even though the thread B got terminated ,the child process did not release the sockets that were connected to it.


My question is ,I have to automate this in C program that if it finds spawned process of g_spawn_commmand_line_sync() defunct, the
health check thread B should be able to clean it without klling the main process.

i could not find any spawn function that will help me find the PID of g_spawn_commmand_line_sync() spawned process.

I get the details from ps commands. But how can I find it in a c-program?
