$ arguments in shell script are not cleared after execution. For
example execute a script “exec.sh arg1″, arg1 is assigned to “$1″. When
you execute “exec.sh” again without the argument, $1 value is retained.
Using “shift” and by assigning argument to a variable will solve this
problem:
# get arguments
EXTRA=""
until [ $# -eq 0 ]
do
EXTRA=$EXTRA" "$1
shift;
done
