Patch Level: 20
Release Status: release
Description:
all numerical tests using -ne, -lt, -le, -gt, or -ge fail. It appears
that only string comparison is used.
Repeat-By:
[ 5 < 10 ] && echo true || echo false
[ 5 > 10 ] && echo true || echo false
n=5
[ $n < 10 ] && echo true || echo false
[ $n > 10 ] && echo true || echo false
[ 5 -lt 10 ] && echo true || echo false
[ 5 -gt 10 ] && echo true || echo false
n=5
[ $n -lt 10 ] && echo true || echo false
[ $n -gt 10 ] && echo true || echo false
The above lines work in the following bash version:
