I am trying to include my directory /usr/sbin in it's serch path for executable files using an environment variable. Would the input be: PATH="/usr/sbin"? And also upon start up, my shell should create the PRINTER environment variable which should resolve to the word sales...would that input be: PRINTER="sales"?

I have what I hope is a fairly simple question to answer. In my ~/.bashrc file I can create this alias:
Code:
alias uChmodDP='chmod -R $1 $2' #specify permissions. and the variables work fine. But I cannot seem to get any love from this alias:
Code:
alias umnt='umount /dev/$1' I realize the likely problem is the variable following hot on the heels of a specific directory, but is there anyway to specify a variable in an alias like this? For some reason I cannot umount usb pen drives by right clicking, and have to always resort to the terminal to do so, which for me is no real biggie, but if I could create this alias it would be an even better no biggie to umount using the terminal.
Actually, the inability to right click to umount usb devices seems to be a Thunar issue since I run xubuntu. Using Nautilus I am able to right click and eject/safely remove devices. Using Thunar however, right click unmount always pukes back an error that the device must have been mounted on the command line or some such BS. But like I said it is no real biggie to use terminal, but an alias would be even nicer. I prefer using Thunar and Xubu most of the time b/c my laptop is quite underpowered.
I am running Red Hat Linux Enterprise 5; I am always using the export command to set environment variables.Are there any other ways to set environment variables and what are the advantages/disadvantages of them?

I know many people have asked about environment variables before, but I am having a hard time dealing with these paths while ensuring I don't mess around with the original settings. How would you go about executing these commands in Ubuntu in terms of environment variables?
put /home/stanley/Downloads/ns-allinone-2.34/bin:/home/stanley/Downloads ns-allinone-2.34/tcl8.4.18/unix:/home/stanley/Downloads/ns-allinone-2.34/tk8.4.18/unixinto your PATH environment; so that you'll be able to run itm/tclsh wish/xgraph.
IMPORTANT NOTICES:
(1) You MUST put
/home/stanley/Downloads/ns-allinone-2.34/otcl-1.13,
/home/stanley/Downloads/ns-allinone-2.34/lib,
into your LD_LIBRARY_PATH environment variable.

I am running an application which requires setting environment variables to be set.At the moment, the way I am achieving this is by exporting the EV at the command line, and then running the app from the command line.I want to be able to run the app from my menu (it is already a menu item after I installed it).How may I set the env var so that it is always available, so I can just run the app from the menu instead of from the CLI?

I am not talking about starting a terminal and exporting environment variables within the terminal, because those variables only exist within that one terminal.

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?

View 2 Replies View RelatedSometimes it is possible to trick a Linux app by calling it like this:
HOME=/tmp/foo myapp
This would make myapp think /tmp/foo is the home directory, it won't try to get the user id, find its home directory via getpwent(). This is useful when myapp must be forced to dump some of its config files into a non-standard location different than ~.
A similar trick can be done like this: LANG=foo LC_ALL=bar myapp
This is useful when myapp needs to be called once with a different locale without having to make the change persistent by using the export bash built-in or even modify stuff in /etc/profile.
Is it possible to pull the same trick with time and date? The goal is to make an app use another time than the system ones. The final goal - to make timestamps that appear in logs/commit messages not being tied to the system time.
I was using the command export, but it looks that after some time the set variables disappears. What is the easiest way of setting an environment variable forever?

Is there some small convenience utility to edit environment variables with a cursor on the command line?

I accidently deleted my .bashrc file. I am a Debian user.Wat should i do??
View 7 Replies View RelatedI want to assign the path of a sourced sub.bashrc file to an environment variable. E.g. if I type (or execute) from a known relative location
$ source ../../someDir/sub.bashrc
the sub.bashrc should set a variable like
export MyOwnLocation=/home/user1/unknownlocation/someDir
The problem is I can't use $0 as reference because the script is only sourced not executed. I also don't want to hardcode the path because the location might change and there will be more copies. Is there an easy way to create this information from within the the sourced bashrc file? I use Gnu bash 2.05b on Suse Linux 9.

View 2 Replies View RelatedI'm trying to compile Ardour on jessie amd64 using the Debian source code (there's already an ardour package but I want to use different compile options). I've applied the Debian patches and have all the required dependencies installed.
Scons quits with a KeyError message from python2.7 saying that os.environ['DEB_HOST_ARCH_OS'] is not defined.
Checking with 'dpkg-archtecture -l' shows that DEB_HOST_ARCH_OS=linux, but 'print os.environ["DEB_HOST_ARCH_OS"]' in python says that name 'os' is not defined. The scons script has 'import os' at the top so it should be seeing it.
How do I make this visible to python (I'm assuming this problem is specific to the jessie python2.7 installation and not python in general)?

I've added an export command to /etc/profile, but the environment variables don't show up when not using a terminal.
For example: when I add:
Code:
To my /etc/profile (then open a new terminal so it registers) and run a graphical program from that terminal, the graphical program can see see the environment variable A.
However if I add the export command to my /etc/profile, then reboot so everything registers, then run that same graphical program from a menu (such as Applications->Accessories->Myprogram), it can't see the environment variable.
What I'm trying to say is basically, my environment variables only show up if I run a program in a shell. Is there a way to set environment variables that will show even without a shell?
