I have an RHEL 5 server joined to a windows domain. However I wanted to add variable lines to be executed each time a user logs in. However I succeeded to put them in /etc/bashrc file and it worked like a charm.
But its annoying that everytime the user logs in to the shell remotely it displays the whole variables that were declared. Is there a way how to add them once and not to display the output each time the user logs in?
I'm running into a problem when I try to set a variable to an awk output in c-shell. Right now my command is Code: set STR_MSG_TYPE = `awk -F{ '/msg_type/ {print $2}' <filename> | tr -d }'/''*' ` I then run echo to see what the output is and it returns blank, however, when I run the same awk command from the command line, I get an actual output of "MT-715". Am I setting my variable incorrectly? I do something similar using the date command to set a STR_DATE variable earlier in the code and it works fine and I use the same syntax.
View 1 Replies View RelatedThe default output audio port Ubuntu doesn't work on my system. It should be "Analog Mono Output/Amplifier", instead of "Analog Output/Amplifier". I can easily change that in sound preferences, just by choosing the right port in the "Output" tab, or by issuing the following command:
Code: pacmd 'set-sink-port' 'alsa_output.pci-0000_00_1f.5.analog-stereo analog-output-mono;output-amplifier-on' The problem is both solutions apply only to a single account, while I would like to change it system-wide, so it applies to all accounts on the system (there are more then 100 accounts - it's a set up for a school).I'm using Ubuntu 10.04.
We're in the final process of building a home, and I had them setup a wiring box where all the coax and cat5 terminates into one closet, which will also house my server. Once we get moved in I'd also like to add speakers in each room to have house-wide music, and ideally I'd like the audio to also run into this box with the master input coming from the server as well.My thought was to setup the server with some basic desktop manager like Fluxbox and use that to drive audio throughout the house, whether it be Pandora, Sirius Radio, or whatever. Since the server will be headless I'll need it setup so we can remote into it from our laptops, but I wasn't sure if VNC or some other RDP variant would work. Ideally we'll need to access a unified desktop so traditional terminal services where each users gets their own desktop might not be ideal

Ive created some custom shell scripts to run during the kernels boot process (they are called from the init script).I was wondering if there's any way to assign a variable that can be accessed between different scripts.For example my first script checks which type of pc i am installing on and assigns the hard drive location to a variable.HARDDRIVE = "/dev/sda1"at the end of the script it calls another script. In this script I cant reference HARDDRIVE as it is blank, to get around this I need to repeat the same code for assigning it.Its more of a space/aesthetics issue but I figured someone might know the solution off the top of their head

I have installed RDGEN which comes with VPFIT package. When I run the program it says:
"Failed to find help file"
But I ran the program from its main directory where all the files including help files exist. I think maybe the problem is because of this that THEY say:
"Some environment variables should be set before starting RDGEN".
But I do not know what does this mean and how to do that.
These are the variables:
-ATOMDIR
-RD PRSETUP
-RD PRSETUP
-RDSTART
-VPFSETUP
-VPFPLOTS
Would it be possible for you to tell me what does Setting Variable means in this case?
Is there a way I can write a file that contains the text which assigns variables, e.g. string="hello world" in a file say, variables.txt and have a shell script assign those variables locally e.g.

echo $string
and when I run the script I would get an output of
"hello world"

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?
View 1 Replies View RelatedI always have to google about setting environment path variables when I install new software. My basic problem is that I dont know whether these variables need to be set globally or not. I have read a number of mails/tutorials which say that Environment variables should be set by simply doing an export ..eg EDITOR=nano export EDITOR
additionally I have read that it should be written into /etc/bash.bashrc
But are these really global variables or local? I want the variables to be set
even after I have logged out.
so I could also write the variable here...
/etc/environment
or here
/etc/profile

View 2 Replies View RelatedI hav a shell script that outputs few variables. i want to output them in a table format. any unix commands?
The output i need is:
I'm aware that one can export make variables to other makefiles; however, how does one export them to the environment of $(shell)? Take the example below:
Code:
export TEST
VARIABLE=$(shell echo $$TEST)
.PHONY: all
all:
#$(VARIABLE)
In this example, I might call make TEST=test. The goal is for $TEST to be available to the environment of the shell escape. This is because I need its value in a script which is called. For example:
Code:
VARIABLE=$(shell i-need-TEST.sh)My current solution is the following:VARIABLE=$(shell export TEST="$(TEST)"; i-need-TEST.sh) but this only works if I know all if the variables needed at that point (as opposed to being able to export variables in included makefiles.) Is there an easy solution?

I am trying to modify a script for research purposes and am having difficulty here as I have little prior experience with C-shell scripting.
The script looks as follows (it includes tcl commands like runFEP that you can ignore)
#!/bin/bash
for ((old=1, new=2; old<=4; old++,new++))
a1=${old}%50
a2=${new}%50
do
cat > input${new}.conf <<EOF
${a1}
code....
My question: I keep getting a syntax error when defining my two variables a1 and a2. I essentially need these variables to be
a1 = value of variable old divided by 50
a2 = value of variable new divided by 50

Placing the customized ones in~/.local/share/applications works, but you have to do that for all users (pain!). So, what folder do they go in for system wide changes, but safe from updates?
