Caution different shells have different magic for setting shell
variables and exporting them to the environment. A variable in the
shell need not be exported to the environment. If it is not exported
it will not be visible to child/sub processes.
If bash is the shell try these
BARK=woof
echo $BARK
env | grep BARK
export BARK
env | grep BARK
export
set
Older shell (sh) required two steps to set then export
a variable. "csh" had two magic words set and setenv
to pay attention to.
See also the man page for bash and environ (man 5 environ).
