While on scripting issues, a tip: if statements (nd while etc) take a command
list as argument. You're not restricted to [ ... ] (which looks like a syntax
thing for testing stuff, deliberately so, but is simply a command in the general
sense). So you can write the above as:
if ping -c 4 -w 10 $dest; then
...
else
...
fi
which reads much more intuitively to my eyes.
I'm also fond of the
while echo -n "prompt> "
read answer
do
...
done
style, too.
