I was looking at etcxyvision/xyv.shpaths today and suddenly wondered, is there a difference between this (as it appears in the system generated xyv.shpaths):
export XYV_EXECS ; XYV_EXECS="/opt/xyvision/xz"
and this (which is a common example in /bin/sh documentation examples):
XYV_EXECS="/opt/xyvision/xz" ; export XYV_EXECS
??
