General :: How System Know It's Collection Of Command Line Programs
Aug 23, 2010
I just started using ubuntu after being a long time windows user.
what i find really interesting is that in command line, i can type many programs and commands, eg firefox can be run via command line from anywhere. In windows cmd prompt, im used to having to run the .exe file by first navigating to it, then being able to run the .exe.
what i wanna know is how does linux know all the programs at the command line?

In Windows, if I have a console window open, type winmine, and press enter, Minesweeper will appear, completely separate from the cmd program. The Minesweeper instance is not tied to the command prompt in any way that I know of, with the exception of Minesweeper's parent being set to that instance of the command prompt. It's different in Linux, however.
In Linux, if I have a console window open, type emacs and press enter, Emacs will open, but it seems tied to the command line. Specifically, it appears that I can't use the command line anymore until that instance of Emacs is closed. Is there a way to replicate the Windows behavior in Linux?

I'm trying to run a home radio server here, and when I run one of the programs.. It continues to run and I cant go back to type any other commands to finish the process. Is there a special key combination that'll get me back to to the command line without killing or stopping the process?

I love Ubuntu Linux - especially the commmand line. But I have to admit that, at least for now, Windows is more user-friendly - there's more software for it, more drivers, and more stuff just works.
Knowing that Mac is built on Unix makes me wonder if it's the sweet spot between them. But I wonder: how similar is the Mac command line to Linux's bash? Could I pick right up with using vim and bash scripting and git, etc? Would common commands like changing directories be different? Does anybody know an online "compare and contrast" resource?

On our server we have a certain directory, say /storage, that contains many large files. They are all compressed (gzip). Many of our users are not computer-savvy, and so when one of these files is needed, they will copy it to their own directory. Consequently, we have multiple terabytes of duplicate data. I'd like to enforce an alias whereby if someone tries to use cp on a file from /storage, they will instead create a symbolic link. My idea was something like:
alias cp='cp.storage'
File cp.storage:#!/bin/sh
truePath=$(readlink -f "$1")
[code]....
The conditional checks whether the file being copied begins with "/storage". The problem with this is that if someone wanted to use cp with any options on a file not in /storage, those options would be obliterated. Can someone guide me as to a good way to accomplish this? Either a way to get the options from cp into cp.storage, or another approach not using alias this way. Everyone will be using bash.

I'm trying to create a liveCD/USB for use of myself and my family. The idea is to set up the LiveCD to look like their used to seeing it. I know I can just copy the homedirectory but I wanted to do it via script so new user accounts could also have the common bells and whistles we use.So really I have two questions.1. Is it possible to add programs to the Gnome Tool Bar from command line? aka via a script2. Is it possible to modify the default panel template so new users get my changes?

We are having a lot of trouble with this.
We need a command line version of Linux like ttylinux. Any command line will do with the latest kernel. It should be around 50 megs.
But the problem is, all these small Linux versions are LiveCD or have a compressed file system.
We need a SMALL linux distro, that we can install UNCOMPRESSED (no squashfs etc) on a hard disk.
This is so simple I'm sure I'm missing something..

I need to organise an external HDD such that there is no more than 500 folders on it.
Ubuntu's "Properties" pane shows only the file count, not the folder count.
Is there a simple CLI line that will tell me the number of subdirectories?

As a strategy for learning linux I have decided to adopt using a lean windows based approach. I want to focus on command line machine system, network basics, and file management knowledge. In other words find out how desktop manager does it's business, so I know how to master my machine, but by and large once I have made my choices, leave it alone to do just that.
I figure I should know how applications are internally configured etc., but I also figure an apps GUI and config choices should take care of installations, and program usage as in M$ windows. Surely taking care of an applications dependencies are the responsibility of the developer, are they not?
I am working my way through "Rute User's Tutorial and Exposition (Version 1.0.0)" right now for an overall viewpoint. Can anyone suggest a specific source for a point by point explanation of the command basis of a generalised "desktop management" application (KDE,LXDE)? Better yet would be if it had some parallel comparison of the varied approaches taken by different distributions of linux.
A secondary question, is that allowed? Up to a certain point in Ms windows, a thorough knowledge of DOS 6.xx would theoreticaly enable one to more or less duplicate the actions of the windows overlay. Is there a basic distribution (or subset in all of them maybe?) of linux that would be consistent with that paradigm? What would be analogous to DOS batch files, or GM-Basic? Oh! that's 3.I am certainly appreciating the depth of this forum, and the breadth of knowledge among you forumite's. Reading it is time well spent.

I'd like show a certain line or lines of a file with context, kind of like a unified diff, on the command line in Linux:
$ (something) -l 154 stuff.py

I just booted into Linux and the Update Manager prompted me to restart. After the restart the GRUB interface I expect to see is no longer there and now it is just a command line that says press tab for more options. I have not got a clue with shell language as I have had no time to learn it as of yet. Do I need to uninstall and reinstall Linux or is there a command that can be typed that boots up the operating system. Even better if there is something I can do is there also another command that can bring back that interface I was used to.

After installing the 10.10 Maverick Meerkat, I decided to have a new partition and install Windows 7 on it for development purposes. So this is the method I worked with:
Partitioned the hard disk with gparted
Formatted the drive in NTFS
Installed Windows
Booted into Ubuntu 10.10 Live CD and re-installed grub on the MBR Now after restarting the system a grub command line boots up. I was able to boot into ubuntu with the following commands:
Code:
find /vmlinuz
kernel /vmlinuz root=/dev/hda1 (or its equivalent)
initrd /initrd
boot
Is there any way how to load up the grub GUI with the options to boot up Ubuntu or Windows 7 respectively?

My computer is a netbook with no optical drive. I had a friend bring over an external CD drive to burn the live CD, but I don't have that now. Since then, I've messed up my install beyond easy repair, so I was wondering if there was a simple (or perhaps not so simple) command that would reinstall every package from the software repositories (I do have access to the Internet, just no GUI). I'm talking about a clean install here.

I'm a Linux newbie and don't know how to do a lot of things. Five months ago, I asked a friend at FreeGeek Columbus to delete the extaneous operating systems from my computer just leaving the one I used, and he accidentally deleted them all. No problem, I'll just reinstall when I get home. But everytime I try to reinstall K/Ubuntu, I get an error message saying
Installation Failed. The installer encountered an error copying files to the hard disk:
[errno 5] Input/output error.
That happens with four Ubuntu installation Cds, three live Ubuntu Cds, one Kubuntu live CD, and one Fedora live CD. I suppose there's a problem with my DVD rom. PCLinuxOS and openSUSE, however, do install, so those are what I've been using (I've only recently ceased with openSUSE, for the time being). Today, however, I got lucky trying out something different. I used an Ubuntu 9.04 alternative CD (not live as they abort when they come to the input/output error message) to install the base system and grub with lvm.
It allows me skip over software installation which is where the input/output error message happens. It boots to a command line. I don't know what commands to use to get the software to install from a mirror, or how to install repositories from the command line. I've never had Kubuntu, per se (only Ubuntu with the KDE desktop); so since PCLinuxOS GNOME 2010 (a rolling distro) is more stable and polished than Ubuntu 9.10, I'd like to fill my base system out with Kubuntu software.

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
