The status command takes two forms. In its first form in which no arguments are given, it writes out the number of warnings, errors and severe errors that 1) were generated by the previous command and 2) have been generated during the entire shell invocation. In its second form it takes from one to three arguments each of which specifies a diagnostic severity and a number. The status command compares each of these numbers with the number of that diagnostic generated by the previous command and generates a severe error if they differ.
Syntax : status = "status" {s ("w"|"e"|"s") num}0..3
Examples: status
status w1 e5 s1
status w4
status s1 e2
The status command was introduced to test the status results of commands during their debugging. It is also useful for checking to see that the right number of diagnostics have been generated at particular points in test scripts.
