Description:
all numerical tests using -ne, -lt, -le, -gt, or -ge fail. It appears
that only string comparison is used.
Repeat-By:
# the following two lines work
[ 5 < 10 ] && echo true || echo false
[ 5 > 10 ] && echo true || echo false
# the next three lines fail
n=5
[ $n < 10 ] && echo true || echo false
[ $n > 10 ] && echo true || echo false
