[Freeswitch-users] Using Unix Environment Variables in FreeSWITCH vars

[Oleg Stolyar]

Hi,

I have a somewhat unusual question.  Can I use Unix variables somehow in
vars.xml?

I have an environment variable $FOO.  I want to define a variable in
vars.xml like this

<X-PRE-PROCESS cmd="set" data="my_var=value_$FOO"/>

Thank you
*Oleg*
