Man bash, look for builtin "test" and find a bunch of tests defined
there. Keep in mind that "test" and "if [ ... ]" are equivalent in bash.
I don't know how much other code surround this, but I deduce (admittedly
incomplete information) that you have a reducing list operation going?
If so, maybe something like
# Initialize remaing list and then
set "$remaining" # If empty $1 is null
while [ -n "$1" ] ; do
echo "$1" # remove this
kill -9 $
shift
done
$ remaining="9997 9998 9999"
$ while [ -n "$1" ] ; do
> echo "$1"

9997 9998 9999
