newbie programming question
 

Hello, I have an app that reads the data from some archives. I want this app to work for all the system, wherever the call is done. For that reason I have put this app in the path, but how can I make it to read from the place that is the data?

In other words, MyApp needs Mydata, but cannot find( I have to "tell" somehow to the app that the data is somewhere or export the data somehow.

HELP...:confused: :confused:

Maybe a configuration file? You can place path to the archives inside.

Thanks, I tryed to do something but I am too ignorant.
Well, I have done something like this,
Myexe is in /usr/bin

The file name is DATA.

PATH="$PATH:/usr/bin"
Mydata=/usr/lib/Mydata
export Mydata PATH

(I have no idea, but that is what I think it should be)

Then I do chmod +x DATA,and execute. But Myexe does not find Mydata yet.
Any idea?

even if you 'export' a variable,it's not available in the current shell.

maybe that's what you're running into. Try '. ./DATA'

For instance, if I want to write a script that sets up a bunch of environmental variables in the current prompt before I login, I'd have to run '. /path/to/script'. Notice the preceding '.' followed by a space.

For example , I frequently have to change the CVSROOT enviroment variable before I run the cvs command. The problem is I have multiple CVS trees tracking and a different CVSROOT for each. the '-p' option of cvs can be used, but that's a long command. So I write a script for each source tree eg...

-----
#!/bin/sh
export CVSROOT=".....
------

Then run the script '. ./cvsroot1.sh'

The '. ' specifies that the script runs in the current shell. So you can log yourself out by calling the 'exit' program in one of those scripts for example

Thanx, do you believe that I've been changing the configuration file for may be 8 hours. . ./DATA, and thas was all!.
