Ubuntu :: A Bootable CD To Get To An Interactive Command Line?
Jan 19, 2011
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 using a java application that runs as an interactive command line (in a terminal). My problem is that it's rather unfriendly as an interaction mode as it's minimalistic: it doesn't allow going to and fro with arrows, there's no history and so on. So I have to type all commands every time and have to retype it if I missed something at the beginning of the line, or I have to copy and paste from a txt editor. The strange thing is that I have seen the same application running on a Windows box and allowing for all the sugar. So I'm not sure if it's because of the shell script I run (as opposed to the .bat) or whether it has to do with system or profile settings in my shell.
For information, the shell script starts with: Code: #!bin/sh I've replaced it with: Code: #!bin/bash
In hope I would have something closer to my normal terminal. The app runs but it doesn't change anything to the interactive mode. I'm rather clueless regarding sh/bash and so on. I've seen the manuals but I'm not entirely at home understanding and using their options. I know that there's a .bashrc and perhaps something like a profile somewhere, but I don't really know how to do things with these without risking messing up.
i've gotten my fedora 12 to the point where i can run python3 scripts from command line and can call up python 2.6.2 idle with the command 'idle' from command line. what command will call up python3 (3.1.2 to be exact) idle?
I'm trying to start bash with a command and have it interactive like this:bash -i -c "echo Welcome!"As in, execute the command and allow me to use it as an interactive shell afterwards. (I'm doing something more complicated than echoing, but this doesn't work.)I've tried this from a running gnome-terminal, from one gnome-terminal to a new one withgnome-terminal and from the Alt+F2 program launcher (with "Run in terminal" ticked).
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?
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 know my way around MS Windows much better, but I just don't feel right trying to program something for Android on a Microsoft operating system. I am interested in Android programming so I followed the instructions on [URL] to install the environment on my computer...
I just installed the JDK, SDK, Eclipse successfully (or I assume):
* When I get to Step 4 where I'm supposed to run 'android' it will not run. I get the error message "android: command not found" (I am definitely in the right directory).
** When I double-click it in nautilus, it opens up in gedit. I can set the permissions in nautilus (through the properties - Allow executing file as a program) and get it to work,
how to pass something more than a one-command startup for gnome-terminal. I will give an example of what I'm trying to do here:
Code:
#! /bin/bash # #TODO write this for gnome and xterm
[code]....
This same error occurs if the gnome-terminal line is changed to
Code:
gnome-terminal -e mcTerm
Is there any way to pass more than one command on to gnome-terminal? I have tried various single and double quoting senarios and in a final attempt, I abstracted to an exported function all to no avail. Perhaps even though gnome-term is better at many things than xterm, xterm trumps it in this instance.
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.
$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?
which does not work on the invisible directories (why?). When I used ".*" as wildcard it changed all (visible) files including the parent directory (the one I was currently working in which is the "dot") . I can change the invisible directories owner and group using dophin but how is it done from the command line?
I am trying to learn how to pass more than a one-command startup for gnome-terminal.
I will give an example of what I'm trying to do here:
Code: #! /bin/bash # #TODO write this for gnome and xterm USAGE=" ${0##*/} [-x] [-g] code....
However, running with the -g option to invoke gnome-terminal, I get a "There was an error creating the child process for this terminal" error.
This same error occurs if the gnome-terminal line is changed to
Code: gnome-terminal -e mcTerm

Using netbook asus 1005ha with lucid beta 1 with most of updates on learning to use the CLI and headaches cd command does not seem to reconise directories here is a sample
Code:
yeh i know read the f#####g manual i am but any help would be greatly accepted tried sudo with same commands same problem did have a problem on my debian system that was to do with paths this is not the same on a different footnote anyone thinking of upgrading to lucid sit tight on 9.10 there are still to many issues that need ironing out for a system that is your main system.
creating a bootable floppy from a bootable floppy image on a NON Linux machine I am trying to install dsl (damnsmallLinux) on one of my old Compaq 2000 Deskpro machine having 256RAM and 2 GB hardisk. (which I hope to increase to 8 or 10 GB ...can I use a larger disk capacity??) I have downloaded the floppy bootable image from the website using a machine a fedora OS machine that does not have a floppy drive. I have even converted the image file to an iso file. I can copy this image file or iso file to the Compaq machine but how do I use it as a bootable floppy? OR how do I create a bootable floppy disk from this image?
I have a cdrom (bootable) that I want to copy over to a usb stick, and have THAT boot the system (Adding other files to it before hand) I know it's easy, but how? I've already made a iso of the cdrom.
How can i copy my G4L bootable CD into a partition, so thar i can boot from it, and not use the CD anymore?The idea is based in the fact that i am so lazy ... that opening/closing the CD is getting on my nerves
If I dd copy a bootable usb drive to an iso will the iso be bootable?
I haven't tried it yet, but i'm going to. Heres the situation and tell me if I'm crazy.
I have several bootable CDs I use at work to do different things, so I went ahead and made a multi-boot usb stick with the isos on them and everything is golden. When i need something else, I am able to slap the ISO on the usb stick, edit the menu.lst and I'm good to go.
The problem is, for some of our equipment I have a bootable USB stick that I have to use. I tried copying the files on the bootable USB to my multi-boot usb and setup grub to boot it (which admittedly I'm no expert at), but have had no luck.
So now I'm thinking, I'll use dd to copy the bootable USB stick to an iso (using bs=2048) and then do my normal setup with an ISO and maybe it will work.
I have slackware on a bootable flash drive, and the pc onto which I want to install slack won't boot from a flash drive. So how do I burn a bootable set of CDs from my flash drive?
How can we do everything, or as much as we can do, from the command line? In particular, I am trying to get rid of the top panel in Ubuntu. Because,
1) It takes unnecessary valuable space. 2) Even if I use a huge monitor, it introduces distraction to me while working.
I created a shortcut so that with a single keyboard key I can open a terminal. For example, if I want to restart the computer, I use: "sudo shutdown -r now". Or I can even create a shorter alias. So I do not need the logout menu. But my problem is, some programs put an icon on the top panel when they are working. So, what is the best way of using command line, and getting rid of the top menu.
I was wondring if 7zip still only runs in the command line. I searched and got a bunch of old threads like this: [URL].. but I'm not sure if that has changed since 2007. A GUI would be awesome.
I have a virtual private server that I SSH into. While I am using SSH, I need to be able to FTP from command line to another server. I want to do this in the easiest most sure way possible. (I am not using my real IP below for security.) I have tried the following commands.
sftp 10.99.99.99 ssh: connect to host 10.99.99.99 port 22: No route to host Couldn't read packet: Connection reset by peer ssh 10.99.99.99 ssh: connect to host 10.99.99.99 port 22: No route to host
About two months ago I upgraded my dual boot Linux-x86-64 Vista from Heron to 10.04 Lucid. Initially everything worked fine including wireless etc. Once I accidentally changed a few /etc permissions which caused a problem, but fixed it going into recovery mode. For the past weeks, I only used the windows. Over the weekend I tried logging into Ubuntu, the gnome would not come up. So, I went into recovery mode and typed "sudo apt-get update && sudo apt-get upgrade" which also went through. However, after that I lost the recovery options. I had used that command very successfully in the past. Right now, I have no command line that would allow me to type something. I was wondering if there are any keys Alt+Del + something that would give me a prompt I can work with. I'm totally baffled as to how this can happen.
