Corey Brune <brune@sdf.lonestar.org> types:

Or try a here document if you really want it in place (and I changed
the s to a c to make it easier to read):

ex <<EOF
1c
/compat/linux/bin/sh
.
w
q
EOF

Though you'd probably be a *lot* better off using sed for this.

mv script script.old
sed '1s;^.*$;#!/compat/linux/bin/sh; < script.old > script

or maybe that should be:

sed '1c
