How to EXPORT library's absolute path which defined in cds.lib TO bshell variable

I have get a view list like "LIB CELL VIEW"

I wanna see some detail infomation (link/size/property) by using "ls -ltr $LIBPATH/LIB/CELL/VIEW" (the command can be constructed by vim or other txt editor)

How can I get $LIBPATH from current virtuoso enviorment?

=====

#cds.lib in virtuoso start up folder:

include  /PREOJECT/common.lib

#/PREOJECT/common.lib:

DEFINE LIB_ZEST /data/XXX/LIB_ZEST 

I have tried in terminal:

1. echo("$LIB_ZEST ")  -> Undefined variable
