what i need is to execute a script before reboot actualy the system reboot faster than the script execute how can we force the system to wait for the script complete execution
its for my 11g database [URL]
i m using gcc to compile certain programs.they get successfully compiled but fail to execute.Here is a sample code and the error [tommy@tommy cprog]$ vi test.c
#include<stdio.h>
int main()

a similar problem arises with codeblocks for the same program.the error is the same even when it is just main() and absence of return 0;
the problem exists also on c++.i m using Fedora 15
I have been trying to get my development box up and running and I decided to do some CGI work in Perl and I am getting a 500 error on Apache 2. I have checked all the perl settings and the script runs fine on the CLI. I am simply passing a textfield from a HTML form to Perl. I was using the standard CGI.pm calls but I modified the script just to use print statements to make the output page. The script has one textfield in it, as it was just supposed to test the CGI.
I have the UserDir directive active for my user and I did some modifications to allow CGI execution from my home directory /public_html/cgi-bin/. the script will not run from the main /var/www/cgi-bin directory either,that also returns a 500 error. the permissions are 755 on both copies of the script in the cgi-bin directories.
I am trying to set up a simple script to automatically invoke streamripper to record my favourite radio shows. The script works fine in a terminal window (Konsole), but when scheduling this as a cron job (KCron via SystemSettings) a Konsole window pops up catching the streamripper output.
Now stramripper can behave with the --quiet option, and I set output redirects "> /dev/null 2>&1". Inside the script or on the command line of KCron.
Quote:
sh myscript.txt >/dev/null 2>&1
...or just as the script without the "sh" command. Same result. Still the same annoying Konsole terminal window pops up, now with no other content than what Cron obviously generates at the end of the script execution:
Quote:
--------------------------------------------------------------------------------
End of script execution. Type Enter or Ctrl+C to exit.
--------------------------------------------------------------------------------
Well, the whole point of this cron scheduling was to avoid manual intervention and create the MP3 file of the radio show automatically. how to avoid the terminal window completely?

View 6 Replies View RelatedI am trying to write a script to set the SGE job execution order. I named each job with 'job1', 'job2' and 'job3'. I want my script to do: When 'job1' execution is complete, 'job2' is executed; when both 'job1' and 'job2' are complete, 'job3' is executed.
First, I tried this following script and it worked well:
########
qsub -N job1 run1.sh # run1.sh includes "mv file_name1 file_name2"
qsub -N job2 -hold_jid job1 run2.sh # run2.sh includes "mv file_name2

We are on our first Linux platform and I am trying to coordinate a distributed application backup across multiple machines. I am trying to write a script in which I would have used RSH to execute scripts on the other servers. We are no longer allowed to use rsh, and someone suggested ssh. I am using that instead of telnet, but I am not sure of the syntax"rsh server [-n] path/executable" is what I would have used, just not sure of the syntax for ssh

FYI:
uname -a

Question:
Upon logging in (typically, for the first time each day) I would like to see a console window/shell or a simple terminal-emulator/shell automatically open up.
The reason is: In order to get my .bashrc to execute I have to log-in, then bring up an xterm or some other terminal-emulator.
Background: My .bashrc has a once-per-day routine/section that will set up my desktop to look the way I want it on my initial log-in (primarily with my Java applications up/running and displayed and waiting for me).
Then, later on that day whenever I bring up new bash shells, my .bashrc is executed but that once-per-day routine/section is no longer executed.
I need to find out the processing or operating time in milliseconds or in nanoseconds for the instructions or for the whole process!
for eg :
I need to calculate the time taken to execute :
And i dont want the time for whole program :
I have seen command like $rm aa dd cc bb ee then something like $ >> zz // it removes zz also Where aa dd cc bb ee zz are the files in my directory. Do not know exactly.

I have a file named "test.txt". It contains the following:
Hello $USER1
Your boss is $ADMIN1
Now, I want to do something like this:
export USER1="World"
export ADMIN1="Me"
cat test.txt > test2.txt
And achieve something like this when I view the contents of test2.txt:
Hello World
Your boss is Me
The problem is, it's not that easy to achieve. I don't want to do the "echo Hello $USER1 >> test2.txt" because I'm planning to implement this on a MB-sized text file.
Today I installed starDict in my Fedora LiveUSB, after I reboot machine. The system backtrack the original one, and then I update the kernel, the system also backtrack.
Why LiveUSB have this function. Can you explain theory about LiveUSB.
I'm trying to save the output of the script I wanna run but for some reason I cant manage to do it with "script.sh > Output_4.txt"
The thing is that the script was already run and it extracted some directories so when I try to run it again (to save the log to a Output_4.txt) bash says (see screen-capture) and of course the log's empty!!!!
Now my script is able to start server, But I am still have some problem with my script. When the start server command is executed, the control does not pass the line and does not execute further of that line.what is the problem and how can I get smooth execution of the my script. My Script:
SUBIT="su - adminuser -c "

I have never set-up a chroot-jailed environment before and I am afraid I need some help to do it well.To explain shortly what this is all about: I have a webserver to which users send python scripts to process various files that are stored on the server (the system is for Research purpose).Everyday a cron job starts the execution of the uploaded scripts via a command of this kind: /usr/bin/python script_file.pyAll of this is really insecure and I would like to create a jail in which I would copy the necessary files (uploaded scripts, files to process, python binary and dependencies).
I already looked at various utilities to create jails but none of them seemed up-to-date or were lacking solid documentation (ie. the links proposed in How can I run an untrusted python script)Could anyone guide me to a viable solution to my problem? like a working example of a script that creates a jail, put some files in it and executes a python script?
In bash shell, is there a simple way for me to monitor the time taken to run a script and output the time taken?
View 1 Replies View RelatedProblem started after installing a new firewall in my network. originally after installing the firewall there would be a 10 second delay after entering a command before it was processed, the command would be executed however there would be an error, i forget what it said, something about not being able to resolve my domain name (and it would give my domain name). i realized this was a problem with my NAT, so i configured DNS forwarding on my firewall so that any attempt to access my server using my domain name from inside the network would point back at my server. after setting up the DNS forwarding i no longer receive the error about my domain name being unreachable, however there is approximately a 30s delay between entering a command and its execution.
the problem is hardly critical i do not see any more serious problems, it is just a pain to do any work when every time i try to do something i have to wait for it to execute.
How do I create a command to launch a program and then have the terminal wait for a specified time and then move on to the next command?I'm wanting to create a startup script, and I need program B to wait until program A has finished loading up.

I need to insure the "writer" to named shared memory (small size, 160 bytes) completes his task such that the many "readers" always get the latest data. The machine is a multi-processor (8 CPU, 24 Gig RAM), non-real time system. The system has multiple processes that are also multi-threaded. Thankfully, there is only 1 "writer" and many "readers". There is no semaphore or mutex locking. "Readers" must not block each other and especially not block the "writer".
By design, it is expected from time to time a "reader" will be in the middle of reading when the "writer" begins to update the data. I want to protect against the case of the "writer" being interrupted and a "reader" completes it's read before the "writer" wakes up and completes it's changes. In this case the "reader" will get corrupt data, some new and some old.
