You could change all instances of:
if [ ! -e FILE ];
then
exit 0
fi
to:
[ -e FILE ] || exit 0
It is more compact. However, I'd rather read if-statements, similar to C, so I
don't have to remember how the '||' works.
'if not exists file then exit 0' reads for me clearer than 'if file exists
returns with non-zero (i.e. does not exists) then exit 0;
Somewhat off-topic, but I find it easy to remember '||' as 'or' or perhaps 'or else'
(and '&&' as 'and' of course).
eg
'File exists or exit 0'
