So what is it that you are trying to accomplish?

Your properties file contains this line, correct?

MY_DIR=/apphome/some/mydir

So, you want to have a shell script variable (MYVAR) to contain this?

If I then echo $VAR what do you want it to contain:

MY_DIR=/apphome/some/mydir
or
/apphome/some/mydir

I want MY_DIR as a variable containing /apphome/some/mydir.

Thanks

MY_DIR=/apphome/some/mydir
export MY_DIR
env
By running the env command you can check that it worked. But remember, if you put this in a script and then do:
exit 0
this script and the process running it will end and the environment is discarded. The env command above was a child process so it inherits MY_DIR. But you cannot set a parent process' environment.

I think I didn't make it clear. Sorry.
Actually, MY_DIR=/apphome/some/mydir is containted in a variable, VAR. That's why.

So if you eval $VAR then the effect should be to set MY_DIR to the value after the equals sign.

Thanks.

Code:
vnix$ VAR="MY_DIR=/path/to/where-ever"
vnix$ eval $VAR
vnix$ echo $MY_DIR
/path/to/where-ever
