----------------------------------------
[~ayushtkn]. After re-checking the patch.. found that following change is not
correct.
{code:java}
@Override
protected void processOptions(LinkedList<String> args) throws IOException {
- CommandFormat cf = new CommandFormat(1, 1, "f");
+ CommandFormat cf = new CommandFormat(0, 3, "f");
{code}
{{min}} and {{max}} args for tail command is 1. i.e. Number of args after
parsing the options.
Fix the test also accordingly.
+1, pending above changes.
