osx yosemite - 'find' with wildcard -


i on os/x yosemite. have performed similar searches following many times: uncertain why not work here.

the search is: 

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

it returns nothing.

now, should return? let remove extension , re-run search:

 $find . -name \*assembly\*

well returns number of items - including first 1 .. ends .jar !

./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

so .. why first search failing?

ok discovered answer. 

 \*

wildcard not zero or more characters match. apparently one or more characters match.

the following does work

$find . -name \*assembl\*.jar  ./mllib-tests/target/mllib-perf-tests-assembly.jar ./spark-tests/target/spark-perf-tests-assembly.jar
