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.
#!bin/bash
command_that_saves_variables_locally variables.txt
echo $string
and when I run the script I would get an output of
"hello world"
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?
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 2 Replies View RelatedI'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 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
I installed Java on a server and anytime I have to start or stop a service that requires the $JAVA_HOME variable I have to manually set it with the export command such as: Code: export JAVA_HOME=/usr/java-jdk1.6.0_21 How can I permanently set this variable?
View 3 Replies View RelatedI 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 want to make a template for Thunderbird. I want the image to be on top and I will put fonts under it. My attempts at inserting an image have resulted in one very large image taking up the entire page.
View 2 Replies View RelatedI have this piece of code with some template strings.
Code:
Big_L: $Big_L
$Big_R
$Lambda_tf
$Epsilon_1
$mu
$n_0
$ms
$Delta_R
$Epsilon_2
$Lambda_d
$Epsilon_3
$Small_N

Doing these commands for multiple command line file inputs is the goal. So I can just type ./script.sh *.mkv in my terminal.This is what I have so far, but it doesn't work whatsoever.

Is there a command that can list the variables that I am using in a script? I mean the variables that I created in the script not the environment or local variables. For example if I have a script that has the following var's like : name=Alex, age=20, postal_code=12345, how can I list them all @ once WITHOUT using echo $name, $age and so on. Imagine I have a lot of variables and i can't echo them all.
View 2 Replies View RelatedIn the following lines I am trying to replace Puppy Linux 5.0 Released with the content of external variable Var. Following lines are in a file called news

I am trying to rename a list of variables in my script using a second list of variables. I want the variables in the second list to replace the variables in the first list such that the first variable in List 1 is renamed after the first variable in List 2, the second variable in List 1 is renamed after the second variable in List 2, the third variable in List 1 is renamed after the third variable in List 2, and so on.
For example:
I know how to rename each file individually, but would like to run Do Loop which can rename all my output files at once.

View 1 Replies View RelatedIve 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 $db and $DATE set in my bash script, then I need to join them like this: mysqldump --user=usr --password=pss --databases $db | gzip > /backups/sqlNew/$db_$DATE.sql.gz;

cwrsync is a great tool for synching "My Documents" to a network drive in Windows. However it uses a portion of cygwin to do this which uses forward slashes instead of back slashes. So, a manually typed command like the following works great: rsync -r --delete --exclude "My Pictures" "/cygdrive/c/Documents and Settings/demo/My Documents/" /cygdrive/j
However, you cannot put a variable like %userprofile% in this as it comes out like this (and is unrecognized): rsync: change_dir "/cygdrive/C:Documents and Settingsdemo/My Documents" failed: No such file or directory (2)
