i'll have to experiment with this a little more...
ubuntu uses dash as the default /bin/sh ... but if our scripts are
dependent on dash being /bin/sh, we should explicitly put #!/bin/dash at
the top of the scripts.
but dash's and bash's built-ins behave differently:
sh
sh-3.1$ echo "\tfoo\t"
\tfoo\t
sh-3.1$ echo -e "\tfoo\t"
foo
sh-3.1$ exit
dash
$ echo "\tfoo\t"
foo
$ echo -e "\tfoo\t"
-e foo
we could use /bin/echo -e to get consistant
behavior for both shells, at a small cost of a little bit of external
binary access.
live well,
