我看不出使用 lbtype_sub 相对于 lbtype 的附加值？
I can't see the added value of using lbtype_sub versus lbtype?
我刚刚读完这篇 IBM 技术说明，但我不明白：
Additional examples of the cleartool find command
看看cleartool find man page and the query language
lbtype (label-type-name)
In all cases, TRUE if the object itself is labeled label-type-name. (Because elements and branches cannot have labels, this primitive can be true only for versions.)
lbtype_sub (label-type-name):
- With elements:
TRUE if the element has a version that is labeled label-type-name.
- With branches:
TRUE if the branch has a version that is labeled label-type-name.
- With versions:
TRUE if the version itself is labeled label-type-name.
因此 cleartool find . -version 将使用 lbtype()，而对元素 (cleartool find -all -element) 的搜索将不得不使用 lbtype_sub().
