Noob linux here trying to understand wildcard matching when using find.

#find /opt/spark/jars -name data*
#find /opt/spark/jars -name datan*
/opt/spark/jars/datanucleus-rdbms-3.2.9.jar
/opt/spark/jars/datanucleus-core-3.2.10.jar
/opt/spark/jars/datanucleus-api-jdo-3.2.6.jar

How come data* doesn't match anything but datan* does?

    Do you have a file in your current directory named data... that doesn't start with datan? – Jeff Schaller Jul 07 '20 at 13:02

    **Always** quote your patterns, e.g. `find /opt/spark/jars -name 'data*'` for the reason that @JeffSchaller hints at. – icarus Jul 07 '20 at 13:11

    Thanks. `find /opt/spark/jars -name 'data*'` did work. After a cursory glance at those shared articles I don't fully understand why so I'm going to go back and re-read them now. Thanks. – jamiet Jul 07 '20 at 14:30
