--- Begin Message ---Package: findutils Version: 4.1.20-4 Severity: important Here is simple examples to demonstrate brokenness of "find". I think you should fix this before sarge. This is such a basic functionality many people rely on. osamu@dambo:a$ ls -l total 4 drwxr-xr-x 2 osamu osamu 4096 2004-08-23 21:40 a -rw-r--r-- 1 osamu osamu 0 2004-08-23 21:41 ab -rw-r--r-- 1 osamu osamu 0 2004-08-23 21:42 b -rw-r--r-- 1 osamu osamu 0 2004-08-23 21:41 c -rw-r--r-- 1 osamu osamu 0 2004-08-23 21:41 d osamu@dambo:a$ find . -name a -o -name b -print ./b osamu@dambo:a$ find . -name a -print # works ./a osamu@dambo:a$ find . -name a -o -name b -o -name ab -print # funny ./ab osamu@dambo:a$ find . -type f \( -name a -o -name b -o -name ab \) -print # works ./ab ./b osamu@dambo:a$ find . \( -name a -o -name b -o -name ab \) -print # works ./a ./ab ./b osamu@dambo:a$ Clearly, match result before "-o" is discared, i.e., functioning as ",". Funny thing is within "( )", "-o" works. This seems to be a work around. Looks like some initialization problem. Please fix it or update man page or in README.Debian to indicate it is broken now and indicate work around.

Then fool like me will not bother you. > Osamu Hello, this was fixed upstream https://lists.gnu.org/archive/html/bug-findutils/2016-01/msg00040.html Please note that -a when specified implicitly (for example by two tests appearing without an explicit operator between them) or explicitly has higher precedence than -o. This means that find . -name afile -o -name bfile -print will never print afile. cu Andreas -- `What a good friend you are to him, Dr. Maturin.
