General :: Which Environment Variables Not Inherited By Bash Shells

Jan 2, 2011

I am using Linux some years, but since I built a LFS, I feel noobish again. Now with the help of BLFS I am setting up my environment and somewhere I incidentally read, that not every variable is inherited by a child Bash shell. As for the $PS1 and $PS2 variables I know, that they are not inherited by non-interactive Bash shells (and there is no reason why they should in my opinion). Well, as for my first thread I hope the title gives enough information on what I want to know. But anyways: Which environment variables are not inherited by Bash shells?

For example, if I'm in csh, I can use `setenv VARNAME varVALUE` while I can use export in Bash. Given that the environmental variables are created, can BASH read env vars from csh and vice versa?

General :: Differences Between Two USB Keyboards?

Jun 24, 2011

I have a proprietary device - something like an iPad screen - which has a front panel display with touchscreen buttons that work internally as a USB keyboard. During testing/debugging I want to connect it to another keyboard via the external USB port.Any application which I open on the device by pressing some characters on the touchscreen accepts input codes from either USB keyboard. I want to limit the touchscreen USB keyboard input only to a specific set of apps.Is there a program which can help me detect which USB port or device the code is coming from? Or someway I can map one keyboard to send a different set of codes? The device is using Linux.

General :: Differences Between XFree86 And KDE?

Oct 7, 2009

My old Intrepid box got old and senile in the hardware, so I had to take it back round the shed and put her down.I buried her next to her favorite tree in the backyard. So yes, I got this new Mini ITX setup with a dual core Atom processor and 4 gigs of ram for my new computer. I'm going to use it as a media center in my living room. However Atom 1.6 ghz is no screamer so I'd like to build a system using a light weight operating environment to leave more power for running programs and playing my media.

I could install the latest version of Kubuntu again but I thought this time I'd try to get a bit deeper into Linux and educate myself. Could someone clarify the differences between XFree86, Window Manager, and a Desktop Environment (KDE/GNOME/etc)? I know it goes like Hardware -> XServer -> XFree86 -> Window Manager (I read the tutorial on linux.org). But where does KDE or a "Desktop Environment" come in? Is KDE a decked out window manager with its own programs that runs on top of XFree86 or what? Or does it totally replace XFree86?

General :: What Are Basic Differences Between Desktops?

Jun 4, 2010

I took the simple approach and installed the gnome desktop, but I have read about KDE and Xfce and am curious. There may be a lot more that I just haven't heard about yet too. So the question is: Without doing a reinstall and messing up the downloads and settings I have now, how do I try a new desktop like Xfce or Kde? Also, what are the basic differences between the desktops?

General :: Differences Between Shell , Console & Terminal?

What are the differences between shell , console & terminal?

This probably sounds like a stupid question but I'm having a lot of trouble clearly differentiating between a shell (such as Bourne or bash) and the Terminal application in GNOME. I realise that both are completely different but I can't seem to find a clear answer written in text. Could anyone clearly distinguish between both?

General :: What Are The Differences Between Shell , Console & Terminal

Jul 23, 2011

I have come across the use of the term terminal, virtual terminals/consoles, real-text terminals but do not understand what terminal refers to. Does it refer to the screen that is in-front of me whilst I post this question or does it refer to something specific?EDITI came across a similar post at What are the differences between shell , console & terminal? and it seems to be similar to the one I posted although am still confused about the use of the sentence Decades ago, this was a physical device consisting of little more than a monitor and keyboard. What does this device look like and how is different to a monitor?

I am only using the 128 character set defined in the original ANSI standard. But as a whole how are the files implmeneted differently. I am not concerned with the display, i.e. if a tab is displayed with 6 or 8 characters but the actual internal representation in memory

One differnce I've hear is the use of (Windows) vs. for line termination (Linux).

General :: Copying And Moving Operations And Their Performance Differences?

Oct 13, 2010

[code]...

Well, let's suppose the file is very large, say 10 GB of disk space it is consuming. We perform the above steps. Which operations: cp (copying) or mv (moving) will be more efficient and less time consuming? The inode number 1566966 which was pointing to the file in my home directory is now pointing to the same file which is in some other directry, i.e. /tmp/. Isn't the inode value getting modified in some ways to point to the correct location / beginning of the data block on the hard disk? If the the physical location of the data would not change then we would not be able to free up space in our home directory. That means the mv operation is copying the file into some other location. In other words, it is also performing the cp operation first and then deleting the file from its original location, my home directory in the case above. However, when a file is copied it's inode value changes. But the mv operation is retaining the same indoe value. So, how to determine which operation - mv or cp - is more CPU-friendly or more efficient in terms of performance and time taken to perform the action?

Slackware :: How Are Variables Set For Interactive Shells

May 5, 2010

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?

Slackware :: Read $PS1 On Non-login Shells?

Jun 6, 2010

Let's say that I have a customized Bash prompt stored as a PS1 variable. My variable gets read every time I invoke a login shell, i.e., when logging in in one of the standard virtual terminal or by invoking xterm with the -ls parameter.

However, when I just invoke the terminal without specifying that it is a login shell, I just get something like: bash-XXX$ as a prompt.

where should I place my PS1 variable so that it could get read even on non-login shells?
