Ubuntu :: How To Do Everything From Command Line
May 8, 2010
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 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,
My system:
Intel i7
Ubuntu 10.10 Maverick Meerkat
android-sdk-linux-x86
eclipse 3.6.2

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.

Code: cmd='date | wc'
$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?

I tried
Code:
chown -R owner:group *
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

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

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.

Lately I have been very interested in minimal Linux distro's. At the moment I am specifically searching for command line only intended distro's (up to date) and even more preferable: command line only distro's available on a live cd or usb. Can anyone of you point me in a right direction or recommend a distro?

I would like to know if I can reboot my headless ubuntu machine from command line to a different OS on the same disk. To clarify, I want to do this without having to manually choose in GRUB.
OS1: Ubuntu on sda1- it is the default OS in an always on server.
OS2: Fedora on sda2 - have to login into this once in a while.
There are no monitors attached with the machine. So I cannot manually scroll through grub and choose Fedora. I want to know if there is a command I can issue remotely to the Ubuntu server to reboot to Fedora.

I'm looking for a way to automatically convert XLS and XLSX files to PDF when uploaded through a Web interface by users. I will probably use phplivedocx for DOC and DOCX files, but I haven't found any library for Excel files.I may use PHP to call a some printing command to make the conversion, but I've never tried that on a server (which obviously) doesn't have Open Office installed (meaning no PDF printer driver I guess)
