Major Description
test-patch.sh uses string comparisons of numbers to decide whether to +1 for javadoc and findbugs warnings.
decisions are made using the following construct
[[ $A > $B ]]
Brackets put the script into conditional expression mode
Operator definition for conditional expression mode
string1 > string2
True if string1 sorts after string2 lexicographically in the current locale.
Examples
$ sh -c 'if [[ 99 > 100 ]]; then echo true; fi'
true
$ sh -c 'if [[ -99 > -10 ]]; then echo true; fi'
true
Arithmetic operations in conditional expressions are defined below
arg1 OP arg2
OP is one of -eq, -ne, -lt, -le, -gt, or -ge. These arithmetic binary operators return true if arg1 is equal to, not equal to, less than, less than or equal to, greater than, or greater than or equal to arg2, respectively. Arg1 and arg2 may be positive or negative integers.
Alternatively arithmetic evaluation mode can be entered using double parenthesis "(( .. ))"
