What many of you probably know is that you can chain commands together with the semicolon. Like so:
unixbench ; echo "unixbench finished" >> unixbench.log
So here we’re running a unixbench, and then directly after, we’re appending “unixbench finished” to unixbench.log.
But what you might not know about is the ‘&&’ replacement for ‘;’. This will only do the next command if the first command returns 0, meaning clean finish.
unixbench && echo "unixbench finished cleanly" >> unixbench.log
And taking it a step further, there’s ‘||’ which does the opposite of ‘&&’. If the first command fails, then the next command happens.
unixbench || echo "unixbench failed" >> unixbench.log
