General :: Variables Between Shell Scripts?
May 20, 2010Ive 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

Programming :: Setting Variables In C-shell?
Jul 12, 2010I'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.

Programming :: Exporting Makefile Variables To $(shell) Environment?
May 12, 2010I'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?

Programming :: C-shell Scripting Syntax Error When Defining Two Variables A1 And A2
Apr 5, 2011I 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
