Please execute my script in dash and in bash, for example.

Hi,
The latest release version of dash does not support assignment syntax in
command arguments. Assignment syntax is special in that it prevents
field splitting. A shorter example is
x="1 y=2"
export x=$x
echo y=$y
This prints y=2 in the latest release version, but prints y= in other
shells (unless you had previously set y yourself): without special
assignment syntax, x=$x is split into x=1 and y=2 before it is passed to
the export command, but with special assignment syntax x=$x is preserved
as a single word.
You can work around this by adding quoting:
local F="`...`"
The current git version of dash does support assignment syntax in
command arguments (like other shells, only for specific commands) and
accepts your script without modifications.
Cheers,
Harald van Dijk
