Top Forums Shell Programming and Scripting BASH Grouping tests in IF statement Post 302948333 by RudiC on Monday 29th of June 2015 03:06:53 AM

In terms of efficiency, meaning to reduce the number of tests, I'd test the most probable one first, i.e. year % 4, which becomes 0 every fourth year, as opposed to year % 400, which becomes 0 every 400th year only (and not for the next 385 years., btw). So in the vast majority of cases, you'll be off with one single test only.

NAME
amt - run abstract machine test SYNOPSIS
amt [-s] DESCRIPTION
The amt command is for use in a Common Criteria security certified system. The command is used to verify that the low level functions nec- essary to enforce the object reuse requirements of the Controlled Access Protection Profile are working correctly. /usr/bin/amt is a shell script that executes tests specific to your system. For a 32-bit system, the tests run as a 32-bit application. For a 64-bit system, the tests run twice; once as a 32-bit application and once as a 64-bit application. amt lists test results with a pass or fail for each test it performs, unless output is suppressed with the -s option. OPTIONS
The following option is supported: -s Suppresses output. EXIT STATUS
