You can pretty much print things how you want by specifying the right
things on the command line. 'lvs' and friends will default to printing
out certain columns, but you can change that.
prompt> lvs --noheadings # print things out without the headings
prompt> lvs --noheadings -o lv_name #print just the lv names
prompt> lvs --noheadings -o lv_name, uuid #print the lv names and
their uuid
etc
for a more complete list, see the various man pages
