Date: Fri, 16 Jul 2004 00:15:45 -0700 From: Alfred Perlstein <alfred@freebsd.org> To: hackers@freebsd.org Subject: RFC: "-exit" option for find(1) Message-ID: <20040716071545.GW95729@elvis.mu.org>
next in thread | raw e-mail | index | archive | help
This adds a primary to find(1) "-exit <arg>", it will cause
find to exit(2) with the <arg> as the exit status.
Useful for finding the first instance of something:
find . -type f -newer ../src.tar.gz -exit 0 && echo hi
this will make find abort with a zero exit status early upon
finding a file newer than ../src.tar.gz.
