General :: How Can Interactive Login Environment Be Duplicated In Cron
May 24, 2010
My execution environment is Linux steamboy 2.6.31-21-generic-pae #59-Ubuntu SMP.If I log in and run a program, the program works properly. The program is a shell script, which executes an environment file, so that path and library settings point correctly.If I have cron run the same program as the same user who logged in, one of the libraries cannot be found. I have sourced .bashrc and the same environment setting file, even though .bashrc executes the same environment file . /home/amr/bin/informix_env.sh
I am trying to assign a user account on RHEL5 Server a non-interactive login but I am not sure if this is the correct command: useradd useraccount -s /sbin/nologinAfter I issue this command, I try to log in with this account and it says the "Administrator has disabled this account" when I enter the password. Does any one know if the command above is correct?
I need to run a script when i login for first time in a day. I may reboot or shutdown and then power on during the day. But i do not want the job to run during those power ups. It should run only once per day.
I need to run a script that prompts the user for some input and takes action based on that input. It must run at the end of the login process, after the desktop is displayed.I tried putting it in ~/.bash_login, but it didn't run. Do I need to tell /etc/profile to run ~/.bash_login? I thought it looked for it & ran it if it was found.
A related question would be - Can I make it so the terminal session that is running the script be the only thing that the user can do? In other words, they can't click on anything on the desktop or in the panels and have it run until after they respond to the input request.
I am having trouble distinguishing between login and interactive shells as they relate to terminals. I understand that a login shell is what is started when you login, and an interactive shell is used by scripts and such. I also get that terminals will use an interactive shell by default. What I don't understand is why interactive shells have no prompt by default. Is their a way to get an interactive shell to inherit the normal PS1 prompt? Is it considered bad to do this? Would it be better to have terminals start login shells, and if so why or why not?
Before you say you shouldn't do that bla bla bla. I know why i shouldn't.
However i have a problem with running sudo commands from a non interactive command line script run using plink.
The automated script needs to use chown and give the current user ownership of some files and folders created by another user.
I can't use things like sudo -s etc as it requires that i enter a password.
I have setup public key authorization in order to login. Do i have to give the root user a password and log in as that. I would prefer not doing this but if that is the only solution i guess i'll have too.
I just build a couple production SLES 11 machines and I'm using an ssh client to connect. However the ssh client forces me to use keyboard interactive login. How can I turn this off so I can use the normal username / password?
Intuitively I think that the Login Shell and the Interactive Shell are the same applications but have access to different environmental variables.It this true? Why is there more than one type of shell anyways? You can change users with the interactive shell, why not log on with it to?
I would like to run an interactive python script in tty1 on startup. This script requires user input outputs relevant data.I also need this script to be run as root as it accesses USB devices (and has to detach kernel drivers).It is an infinite-loop script, so I also want to be able to ctrl+alt+F to tty2 to actually login if needed
Script programming question for the experts. I have written a bash script that works fine if I execute from the shell interactively. However, once I schedule it to be executed via cron, it just wouldn't work. I believe this has to do with cron running in a different environment than the one I am in when I putty in.
The bash shell script does refer to environment variables in the .cshrc file. I guess these aren't available to the cron? How can I load them into the script if I want them to be available to the cron locally within the script?
I'm looking for a way to set arbitrary environment variables for my graphical login on linux. I am not talking about starting a terminal and exporting environment variables within the terminal, because those variables only exist within that one terminal. I want to know how to set an environment variable that will apply to all programs started in my graphical session.
In other words, what's the Xorg equivalent of ~/.bash_login?
In this article about Sun, the author talks about how using a Sun network meant that you could log onto any computer on a network and all of your personal tools and settings would be there. Is it possible to set up something like that with a Windows network? How about Linux?
I have couple hard drives from different linux distro's. on the hdd's are logical volumes created. what i want to do is to backup the data from those hdd's. but when I connect some of them and boot up the system it gives me an error that there are volume group duplicated and it list the UUID. My host system is centos 5. What is the best solution to rename those volume groups or to mount the drives from other systems, so the data will not get lost?
I have a situation where I am in a non-interactive shell. I have tried from within my non-interative shell to spawn an interactive shell but my output still does not goto me. Isn't there a way I can somehow go into /proc or somwhere and make the output my /dev/tty1? Or some way else to remedy this?The situation arises because I drop from my restricted shell environment (a sort of CLI interface), into the actual Linux shell. I cannot change the code of the CLI environment I am just faced with being in the linux shell environment and its non-interactive. Its very annoying to have to put > /dev/tty1 after every command I type.
Not to mention it seems damn near impossible to get pagers like more and less to work properly when your in a non-interactive shell.
My ubuntu 10.10 desktop environment freezes at right after login, with the window prompt to "unlock keyring" in the foreground. The cursor still can be moved around the screen with the touchpad or mouse. Mouseover of Docky elicits the usual animation but there is no response to clicking it. There is no other response elicited from moving the mouse over or clicking anything else on the screen, including the taskbar and the hot corners i have set up. However the screen still goes dim and to sleep when left unattended and can be reawoken. The netbook also still recognises when it is plugged into a power source.
Background info: I have been dual booting windows 7 starter and ubuntu 10.10 desktop edition for about 2 months now on my ASUS eeepc1005pe netbook with no issues till now. The problem only started when i booted up into windows 7 starter without having shut down ubuntu completely. My netbook was hibernating when i mistakenly chose to boot into win 7 starter at the bootloader. Now this freeze happens every single time i try to boot into ubuntu. But i am still able to boot into win 7 starter without any problems.
The same sequence of events occurs each time i try to start ubuntu. The boot goes fine, then the automatic login occurs, then compiz loads fine then my desktop environment appears with all the same windows and programs open on the desktop as the last time i had managed to use ubuntu except that the keyring login prompt appears in the foreground and then everything freezes as i have described.
I have my work PC in the office, and time to time I access it via TeamViewer from home. I have access to it also via ssh, over the VPN connection. I have problems with this setup, when for some reason the work PC must be rebooted (or it just happened by itself - power failure). The Ubuntu gets to the login screen and that's it. I can not access it remotely because the TeamViewer application is not started on that PC yet. I'd like to know, if there is a way how I can access my work PC over the VPN connection - open SSH session, and write some commands, to log in that desktop environment user, and launch the TeamViewer application. Ie, if someone would be looking on the screen at that moment, she would see that login screen disappears, desktop environment is loaded, and the TeamViewer app is started.
If that's not possible, then, I guess, I'll have resort to some alternative remote access tool (ie, VNC) what could be loaded before the Ubuntu login screen is shown. Then I could access it over the VPN connection, using appropriate client.
I just installed Ubuntu 10.10 and when I try to log in to the regular desktop environment, only the backsplash coloring is there. I can, however log into safe mode and see the GUI there. Occasionally, I will get the treat of using the regular desktop environment, but it will ultimately freeze, and if I go to a different runlevel and restart gdm, the same thing happens....only backsplash. Here's what I've looked into, all of which has failed by the way: gdm.conf, URL... even though that "fix" was for an earlier release, and of course reinstalling a few times. *Sigh*I'm running it on a Toshiba Satellite L25-S1217, Intel Celeron, 874MB RAM, and 60GB HD with the stock Radeon graphics card.
Is there a non-interactive way to change a user's passwd short of using expect? I'm using Debian.If not, then I guess I need to get this expect script working:
Code: #!/usr/local/bin/expect -f set username $env(UNAME)
I have installed ubuntu 10.10(gnome desktop environment),in my laptop..everythin was workin well for the past two months...recently,i added kde plasma desktop environment,via ubuntu software centre..now,when i try to log into ubuntu,there is an error message stating "gnome power manager have not been installed correctly.please contact your system administrator",on the topmost right edge of the screen...i tried various commands like,
But,nothing has solved my problem..many suggested that it may be due to low drive space..but i cant use the mv commands too..really,i'm so helpless and its been three days,after usin my laptop..
how can I make my sh interactive by default. That I don't have to always type --interactive everytime I log in. I want it to be always interactive. #2- how also do I turn of --posix mode parmanently ? Is there a line I need to drop somewhere or what do i do.
how to to setup a PXE boot environment. The server contains a LUbuntu 10.10-installation the client is Ubuntu 10.10 Server (I didn't mix up those two...) So, everything is going fine; the client gets an ip-adres, and boots over PXE. The login-prompt is shown. Problem: I can't login. It seems my users are deleted (better not copied). Of course the system (client) works fine when I boot the system from it's harddrive. The only thing I can guess, there going something wrong with:

From the output i am indeed able to login, but do not get an interactive session. I took inspiration for this attempt from using ssh to run a command remotely.
In interactive mode (in Octave, gnuplot, R, etc.) I occasionally press Control + z by mistake. This pauses the program and kicks me back to the terminal.Is it possible to re-enter the original interactive mode (with all the stored variables)?
To reproduce:

How can I recover my session with the variable a defined?
I have just installed Fedora (13) for the first time. It's great ! So thanks to all its developers !
I managed to do many tweaks I wanted to, in no small part thanks to this forum, but here's one that eludes me and my google-fu.
I'd like to customize the login screen (if I grokked correctly, that's gdm). I already saw how to change the background or how to enable automatic login, but what I'd like to do is this :
1. Disable that rather annoying "pong" sound when I select a user,
2. Set a default desktop environment. Gnome seems to be the default environment selected in the drop-down menu, but me, I'd like for it to be XFCE.
I wish to prevent some programs from "phoning home", and to allow other programs to access only specific web servers.Is there any way to interactively allow or decline outbound communication from individual programs on Ubuntu?
I wanna delete a directory with its files and I wanna do that as follows: rm -r dirToDelete Unfortunately, I always get asked for EACH single file if I wanna delete this because it is write protected.... Is there a way to suppress this feedback message so that just the whole directory with its contents disappears?
