What is the point of the { } around some variables?
It's not strictly necessary, except in some cases. i.e:
m=34
echo $m
You don't need it there.
But you would want it here:
f=/var/filename
fname=${f//name/name2}It's when you need to differentiate the variable name from operations around it ... for want of a better explanation ....
