Programming :: How To Turn Non-interactive Shell Into Interactive Shell?
Feb 4, 2011
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.
i need to run a command from a shell script that requires me to answer "Yes" to 2 questions that the command asks before it kicks off. how do i do this? i thought it was something like this.. from inside the parent script:
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?
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.
I recently "upgraded" to the latest skype and now every time I open an interactive root shell, up pops skype. I can close skype then control-C in the terminal window to get the shell I want, but this is annoying to say the least. Maybe my google-foo is off, but all I can find is articles on how to run skype as root, which is no use. I've tried searching the startup files for "skype" (case independant), but so far all I can find is "LD_LIBRARY_PATH=/usr/lib/i386-linux-gnu/ /usr/bin/skype" in the root .bashrc which shouldn't be starting the app.
There are a few things not working properly. Ruby version manager seems ok but untill i get working with ruby i don't know if it is working properly. One thing that is not there is irb Interactive ruby is not available according the the message i get.
Well i have no idea what readline is but i did everything that is on that webpage referance page [url]. I have got a lot of progress and learned heaps about linux shell and bash terminal. The thing is i need to get this going and have tried feenode but it is very foreign and how it works i do not have a clue. I have got 2 things resolved so far through this forum but using other threads in it. i need to get irb going before i can progress to using ruby on Rails properly.
I am using a Eeepc running ubuntu easy peasy its version 9.04 of ubuntu. I need the whole of rails to work and want to get a handle on using ruby version manager along with the apache stack with mysql/phpmyadmin and am using this as a dummy run for setting up a development system.
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?
Any pointers to make a shell script in cronjob or using at to be user interactive. We have a requirement to script a program where it prompts the users in CUI for feedback and capture the output in a text file and act based on the feedback.For eg: At pre-defined time i should prompt the acitve users whether it is ok to shutdown, whose feedback would be captured in a text file. Post which act on the updates in the text file
Code:-ask the user which files they want to sent (files not needed to be in the same directore-tar all the files together-Gzip the tarfile-Uuencode the gsipped file (so more email programs can use it)-ask user who to send email to, possibly more than one person-I want it to be clear and easy to use and display what it is doing while an action is taken place.I have no clue where to begin. I think perl would be the best option, but I am not sure, how would I make this able to run with am email program and I am unaware how to tar and gzip files or Uuencode the gsipped files.
I want to have a script (tcsh/bash/python) that launches a bunch of gnome-terminals (or 1 with multiple tabs). And I want it to execute a command, but keep the shell interactive. Currently, if you type gnome-terminal then it launches a new interactive shell, but if you give it the execute flag, then it executes the command and quits (or stays open, but non-interactive depending on the users gnome-terminal settings).
I have this command which I want to run automatically before I start working. What the command does is dynamic and different for each shell. It takes arguments. So it's not something I can take care of in a .cshrc type file.
I am trying to write a perl script which will give an interactive session to a user to execute command on the server. I have written a small script to do this :
Code: !/usr/bin/perl -w use strict; use Net::SSH::Perl; my $host = '192.168.1.1'; my $username = 'user'; my $login_passwd = 'test123';
I am trying to create a shell script similar to ls, but which only lists directories. I have the first half working (no argument version), but trying to make it accept an argument, I am failing. My logic is sound I think, but I'm missing something on the syntax.
Code: if [ $# -eq 0 ] ; then d=`pwd` for i in * ; do if test -d $d/$i ; then echo "$i:" code....
Is there some type of functional way to read things in the Python shell interpreter similar to less or more in the bash (and other) command line shells?
Example:
Code:
>>> import subprocess >>> help(subprocess) ... [pages of stuff to read] ...
I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.
I've created a simple script based menu. This menu will be accessed by only a certain users via ssh.When user logs in, the menu will automatically run. (configured at user's .bash_profile).How do I force the session to close when user hits Ctrl-C or Ctrl-Break ?In a nutshell, I don't want user to have access to shell.
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)
Posting from Splashtop as i can't get past keytouch-apid in the boot process,Yeah me bad so i would like to disable it so i can complete the process.Using the interactive startup seemed the way to go but how does one get there before udev starts up?Or is there something else i could try.
My problem is: One of my services has failed to start. All I need is just go into interactive startup and ignore that service. The system is encrypted as LUKS. I press 'i' before and after entering the phrase (it asked me "Password for filesystem"). But interactive startup seems not working. All the services go to start without my permission. I mean there is no question such as "Start XXX [Y/N]?"
In the past I used CentOS for some months, and interactive startup (by pressing 'i' on boot time) was fine. I could allow or not what service should be started.
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.
The interactive map on weather.com no longer works for me in Firefox. I'm just looking for some feedback from other users if they can see the map or not. I'm using Lucid with current updates.
I need an non-interactive, symetric, passphrase mechanism that can be used on machines beyond my sys-admin control. Currently, I use the Python code (with variants):
to encrypt and decrypt files (tar balls). The "Password" is generated by a Python code on a singular removable flash drive. It worked with FC11 and Windows, but with FC13 I get an interactive dialog, which gets canceled, and then: can't connect to `/home/{a user id}/.gnupg/S.gpg-agent': No such file or directory
gpg-agent[3432]: command get_passphrase failed: Operation cancelled gpg: cancelled by user gpg: error creating passphrase: Operation cancelled gpg: symmetric encryption of `testdata' failed: Operation cancelled
The operator does not know the pass phrase. This is a single user mechanism which relies upon the mounting of the special flash drive to work. The application is portable across many platforms and hosts, but can only be used by the possessor of the flash drive.
can provide recommendations on any projects that can fully automate the install process of an interactive application. I am doing installs of applications such as websense and they are all interactive. I would like to automate all interactive installs in my environment. I did find the following: [URL]
I am trying to figure out where variables are set for interactive shells? In particular, I am trying to have LS_OPTIONS inherited by interactive shells as it is by login shells. I understand LS_OPTIONS is set in /etc/profile, and this may not be processed by interactive shells but by login shells. However, I also note other variables such as PATH and INPUTRC are set correctly in interactive shells, and these are also set in /etc/profile from what I understand. So how is it determined which variables are inherited by all shells, and which are just for login shells?
I'm still quite wet behind the ears with CentOS/Unix. What I'm trying to do is to setup a non interactive user, where I login with an interactive user and su to the non interactive. I have set the non interactive with /sbin/nologin (through the GUI), but when I login with the interactive user and su to the non interactive user I get the following: "This account is currently not available".
Possible Duplicate:Forward SSH traffic through a middle machine.I am looking to get an interactive ssh session on a remote machine, but must login via a gateway.For example, right now I do the following:
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:
~> octave octave:1> a = [1:10]; octave:2> ^Z
[code].....
How can I recover my session with the variable a defined?
As I have posted here [URL], my laptop powered down during an update because I forgot to plug it into the mains power. Anyway, after going through the thread I referred to above, I learned that I must chroot into the existing installation and patch it up. I can do this using a live CD but unfortunately, I gave my most recent live CDs away and the Live CDs I have left don't recognize the file system on the current Ubuntu installation. (If I remember correctly, the current [broken] installation is 10.04). Downloading a new live CD is a bit difficult as internet speeds over here aren't very fast. I was wondering if there is another alternative bootable CD that I could use to get a interactive command line which I can use to "chroot".
I'm running Kubuntu 10.04 and have activated the interactive map wallpaper. Zooming with the mouse wheel is unfortunately very slow. I have tried to adjust the speed by changing System Settings > Mouse > Advanced: Mouse wheel scrolls by to max, i.e. "12 lines", but it has no effect, the zooming is still very slow. Is there any way to speed it up? If possible I would like to have the same zoom speed as when using Google Maps [url] in Firefox.
