Hi Zen,

I am not familiar with EDM, but this looks like the shell, not EMD is

executing "/opt/myarea/bin/$(ARCH)/command". For the shell, $(xxx)

means: execute command "xxx" and use its stdout output as a value. Try

${ARCH} or $ARCH instead.

I would like to be able to specify command path using an environment

variable in the Shell Command widget.

For example I would like to have path like this:

/opt/myarea/bin/$(ARCH)/command

where ARCH is an environment variable. In my case it can have value

arch-32 or arch-64 value.

When I do that I get an error message:

sh: arch-32: No such file or directory

How can this be done?

Any help will be appreciated.

Thanks,

Zen
