Name

yapp_query - show which yapp device(s) are installed

Synopsis

yapp_query dev1 ...

Description

yapp_query attempts to show which possible devices are installed in NEMO, to make shell scripts more portable. For example for the pgplot device list 
       yapp_query png ps
would return the first device that is available. Here’s an example of usage: 


       dev=$(yapp_query png ps)
       tabplot 1.tab yapp=fig1.$dev/$dev
would be a more portable way. This is a common situation, where on redhat based system the png driver is not installed, but on debian based it is (in 2021).
