Hi all,
In order to avoid using undefined variables one can use the syntax:
echo ${badvarname:?}
which will result in error message would the variable be bad (not "defined" or
empty). This kind of reference is tedious therefore one could use ksh -u (in a
script)
#!/bin/ksh -u
the result is a check upon all variable references, which brings in a new
problem.
while ($1)
do
some stuff with $1
shift
done
is there a solution for such a case?
Thanks
David Harel.
