Question

我在OS / X优胜美地。我已经多次执行类似的搜索：不确定为什么它在这里不起作用。

搜索是：

$find . -name \*assembly\*.jar

它返回 nothing 。

现在，应该返回什么？好吧，让我们删除扩展名并重新运行搜索：

 $find . -name \*assembly\*

那么它会返回许多项目 - 包括第一项......以 .jar 结尾！

./mllib-tests/target/mllib-perf-tests-assembly.jar
./mllib-tests/target/streams/$global/assembly
./mllib-tests/target/streams/$global/assembly/$global/streams/assembly-inputs
./mllib-tests/target/streams/$global/assembly/$global/streams/assembly-outputs
./mllib-tests/target/streams/$global/assemblyOption
./mllib-tests/target/streams/$global/assemblyOption/$global/streams/assembly
./spark-tests/target/spark-perf-tests-assembly.jar
./spark-tests/target/streams/$global/assembly
./spark-tests/target/streams/$global/assembly/$global/streams/assembly-inputs
./spark-tests/target/streams/$global/assembly/$global/streams/assembly-outputs
./spark-tests/target/streams/$global/assemblyOption
./spark-tests/target/streams/$global/assemblyOption/$global/streams/assembly

那么..为什么第一次搜索失败了？

确定发现了答案。

\*

通配符不 零个或多个字符匹配。它显然是一个或多个字符匹配。

以下工作

$find . -name \*assembl\*.jar

./mllib-tests/target/mllib-perf-tests-assembly.jar
./spark-tests/target/spark-perf-tests-assembly.jar

＆＃39;发现＆＃39;用通配符
