I could see virtuoso with which virtuoso:
/tools/cadence/IC06.14.005/tools/dfII/bin/virtuoso
but when I type in
virtuoso
I got
"virtuoso: Command not found."
and the virtuoso is:
lrwxrwxrwx. 1 dubeeloo dubeeloo 39 May 18 17:32 /tools/cadence/IC06.14.005/tools/dfII/bin/virtuoso -> ../../../share/bin/cdnWrapperWithOA2009
