I have written a backup script backing up the data I have worked during the day with rsync and sends me a log in my email. now it works perfect but i want to execute it each time i shutdown my computer in the evening not during reboot or logout.It seems that i can not run it by putting it in init.d and softlinking in rc0.d as K00backup. I think it is because script uses many services like python or smtplib, gnome-keyrings that in that time might have been already shutdown.
I would like to be able to execute a script every time X is shut down (e.g., by Ctrl+Alt+Backspace), namely, logout. Is this possible? If it is, in what file do I put the command/script?
I have a big fortran code for FE analysis. I want to change the code to python. I am curious to know, whether I will get any advantage over speed, If not at least the speed should not be less than what fortran gives. Should I go for it.
When I shut down my computer I want to show some pending tasks that I have to do before leaving the office... I did a local application to manage those tasks, so basically I just want to run a command, and shut down after I kill the app executed. I have already tried with these options:
* /etc/gdm/PostSession/Default --> this works only when I select LogOut option instead Shutdown.
* /etc/rc0.d/K01mycustomscript --> execute script after X is killed
* $HOME/.bash_logout --> This looks like does nothing.
* ./app-to-run && sudo shutdown -h now --> Don't like it for 2 reasons, prompts for sudo password, and can't use my laptop shutdown button.
How could I modify Shutdown dialog ? should I recompile Gnome ? Options? I am using Ubuntu 10.04
Is there, by chance, a fancy name to describe code that must be in a program but will never be executed? In one of my (Haskell) programs, I have some error-handling code that must be in the program to keep the compiler happy (due to the type checking). However I know that, due to the logical structure of the program, it is impossible for the code to be evaluated. I am curious if there is a technical name given to code that must exist but cannot be executed.
Tested on RedHat entreprise 5.5, 5.4, 5.3 I would like to stop my db (not oracle) when the system shutdown or reboot. I have wrote my script for init.d
Here is the head :
The problem is : shutdown -r stop the system before my K script execute. I have not my "blabla" in /tmp/mystop.log
In fact the scritp is for database startup and database shutdown manually it works I mean : /etc/init.d/mystop stop ; /etc/init.d/mystop start So I truncated the scritp until I only get echo "blabla"
This work idealy under HPUX, AIX, and I think I'm missing something "special" for Redhat. I'm quite sure it was ok with redhat 8 and ES 3.0.
I'm doing a program and I want it to execute some code during n seconds. For example e put a command in the shell like this 'ls % 10' and the program should run the command ls for 10 seconds.I'm trying something like this:
i have attached a word doucment with black jack code, i want to know what things are wrong with it, and why it does not run, in python, as it keeps displying error messages such as "invalid syntax"
I've taken the source code for Zlib1.2.3, built and installed in a 64 Bit linux machine. Then when i downloaded Python 2.5.4 source and tried to build(make), i got the following error
gcc -pthread -shared build/temp.linux-x86_64-2.5/opt/cinecert/Python-2.5.4/Modules/zlibmodule.o -L/usr/local/lib -lz -o build/lib.linux-x86_64-2.5/zlib.so /usr/bin/ld: /usr/local/lib/libz.a(adler32.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC /usr/local/lib/libz.a: could not read symbols: Bad value collect2: ld returned 1 exit status
The system is Debian Squeeze/Sid with apt.conf set to Squeeze as the default. Most packages are from Squeeze.
I ran apt-get upgrade and it returned an error-code.
It might be it is this bug: Bug#574153: python-pkg-resources: Missing file leaves it unconfigured
I tried aptitude install -f, to hold it and to remove the package python-pkg-resources, but i am getting told the package would be in a very bad stage, and i should re-install it. That doesn't work.
I usually develop python code with emacs, emacs being in python code. On my desktop a version is installed and/or configured that way, so I easily can choose a region in the code and simply click on a menu option to comment out this block of code (i.e. at the begin of each line in the selected code two '##' are put). That is very convenient.
However, on my Laptop, running F12 and emacs 23.1.1, this menu option is missing! I searched within google and found the hint that by pressing 'C-c #' I also can comment out a selected region. But on my emacs it says: 'C-c # is undefined'. Am I missing something? Anyone any idea how to fix/install/update/solve this problem, so I can easily choose a couple of python lines and comment them out?
I was just reading about the whole boot process on computers and am curious as to why the BIOS can only read and execute code and data from only cylinder 0, track 0 and sector 1 of the disk being booted from? Why can't the BIOS read from any other disk location?
I am trying to write a script (especially C-shell) to execute a fortran code that reads in parameters from keyboard typing. I will have to process this .F code for many times with the parameters the same for all my data files, therefore, I don't have to type in everytime I execute the .F code. But I don't know what is the command in c shell to read in a text files that contains all the parameters I want and can make the shell read in appropriately to feed the .F code.
I have this one last task for this app I've been working on (should have picked something easier for my first project)
It has working "def sav_scr_vars" and "def AddEntry" but these save to a fixed filename when save as defults or ok button is clicked. This is fine but I want to be able to save via the same proccess to a named ~/bin/settings/xxx.set file what I did is clone the to above def's and try to edit them I got the "read file" to work fine from a saved file in this manner. but I can't seem to get the save to filename to work without errors. The cloned def's are "save_as" and inmain.py "write_config2"
the camm2.defaults file goes in ~/.hpgl
copy and paste this to ~/.hpgl/camm2.conf ~/.hpgl/camm2.defaults
The file is always to have a .set extension and only read and write to ~/bin/settings
in ubuntu 10.10, I have installed python 2.7. I would like to use apt-get to install packages to this version of python but I haven't been able to figure out howThings I have tried without success:changing the symlink at /usr/bin/python to point to /usr/bin/python2.7 - even after doing this apt-get still installs stuff to python2.6.Set up python2.7 as the primary alternative using update-alternatives - doesn't work
I have installed a cluster computer with 10 nodes . The manufacturer is HP . All nodes and the master node have redhat enterprise linux installed in them . When I shutdown the nodes from the master terminal using "shutdown -h now" they get shutdown . But they dont get completely turned off . This issue bothers me when the power supply is given , all nodes boot up simultaneously generating a huge heat .
Thing to note : When we shutdown our PC they get completely turned off . When the power supply is given , a press on the Power On button is required to boot the system. But , why does it not happpen in the case of cluster? Is there any other way of completely turning off the nodes from the master terminal ?
i created a /tmp partition amd mounted it like this:" mount -o loop,noexec,nosuid,rw /usr/tmpDSK /tmp" I know i can't execute things in /tmp now but is there a way to execute only one file and no more???

I have a function definition in a Python 2.x script which take a tuple as one of its arguments, but 2to3 has no answers nor any of my searching on how to represent the same in Python 3.x
Recently I installed vncserver (tigervnc) on my desktop. Ever since my computer refuses to shutdown normally. At shutdown the following message pops up: Quote: System policy prevents stopping the system when other users are logged in Then I have to enter the root password to shutdown. If I stop vncserver before, the computer shuts down normally.
