从查找中排除某些文件名模式和目录

我正在尝试查找与 CVS 相比不是最新的所有文件。由于我们的 CVS 结构已损坏（它在某些目录中不能很好地递归），所以我现在正在尝试使用 find 来解决它。

我现在所拥有的是这样的：

for i in `find .  -not \( -name "*\.jpg" \) -path './bookshop/mediaimg' -prune -o -path '*/CVS*' -prune -o  -path './files' -prune  -o -path './images/cms' -prune -o -path './internal' -prune -o -path './limesurvey171plus_build5638' -prune  -o -path './gallery2' -prune -o  -print  `; do cvs status  "$i" |grep Status ; done &>~/output.txt

但不知何故，我排除图像（在本例中为 jpg）的尝试不起作用，它们仍然出现。有人对如何将它们从我的查找结果中删除提出建议吗？

I'm trying to find all files that are not up to date compared to CVS. As our CVS structure is broken (it does not recurse well in some directories) I'm trying to work around it with find for now.

What I have now is this:

for i in `find .  -not \( -name "*\.jpg" \) -path './bookshop/mediaimg' -prune -o -path '*/CVS*' -prune -o  -path './files' -prune  -o -path './images/cms' -prune -o -path './internal' -prune -o -path './limesurvey171plus_build5638' -prune  -o -path './gallery2' -prune -o  -print  `; do cvs status  "$i" |grep Status ; done &>~/output.txt

But somehow my attempt at excluding images (jpg in this case) does not work, they still show up.
Anyone have a suggestion on how to get them out of my results from find?

这失败的原因与混合布尔 AND 和 OR 总是失败的原因相同。

你在这里所说的是真的（用伪代码）：

If (
    File Not Named '*.jpg' AND
    Path Matches './bookshop/mediaimg' AND
    Prone OR
    Path Matches '*/CVS*' AND
    Prune OR
    Path Matches './files' AND
    Prune OR
    Path Matches './images/cms' AND
    Prune OR
    Path Matches  './internal' AND
    Prune OR
    Path Matches  './limesurvey171plus_build5638' AND
    Prune OR
    Path Matches  './gallery2' AND
    Prune OR
    Print
)

现在， print 总是返回 true，我认为 prune 也是如此，所以你会看到，如果任何 OR 匹配，则所有 AND 都不重要。仔细应用括号可能会产生您想要的结果。

This is failing for the same reason that mixing boolean AND and OR always fails.

What you're saying here is really (in pseudo-code):

If (
    File Not Named '*.jpg' AND
    Path Matches './bookshop/mediaimg' AND
    Prone OR
    Path Matches '*/CVS*' AND
    Prune OR
    Path Matches './files' AND
    Prune OR
    Path Matches './images/cms' AND
    Prune OR
    Path Matches  './internal' AND
    Prune OR
    Path Matches  './limesurvey171plus_build5638' AND
    Prune OR
    Path Matches  './gallery2' AND
    Prune OR
    Print
)

Now, print always returns true, and I think prune does as well, so you see that none of the ANDs matter if any OR matches. The careful application of parentheses will probably yield the results you're after.
