sh -c "$DAEMON $ARGUMENTS" is working.
But it is not what I need. I need it with something like `echo $DAEMON
$ARGUMENTS` because the final result should be to gives this to shell vars to
debian start-stop-daemon as in
start-stop-daemon --start --verbose --exec /sbin/$DAEMON -- $ARGUMENTS
Isn't there a way to prevent the shell from removing the quotes? Perhaps with
a more complicated structure of single and double quotes in the definition of
ARGUMENTS?
BTW: ps does not show the quotation:
[01:25:29 /tmp]# ps axf |grep powercom | grep -v grep
8739 pts/9 S 0:00 powercom -m Advice Partner/King PR750 -s 00131581
/dev/ttyS1
