How do I run a command on each file within a directory that matches a pattern?

Question

I'm trying to run a command on every file within a directory (recursively) that matches a pattern. I need the filename of each item that matches for the command however. This is how far I've got:

find . -name '*.jar'

That gives me all the files I'm interested in. Now, I need to run the following command on all those files:

jarsigner -keystore ***** -storepass ****** $FILENAMEHERE

How do I reference the individual items in the output of find, for the command?

Answer 1

for i in `find . -name '*.jar'` ; do jarsigner -keystore ***** -storepass ****** $i ; done

Answer 2

If jarsigner takes only one file name at a time, use either

find . -iname '*.jar' | xargs -l jarsigner -keystore ***** -storepass ******

or

find . -iname '*.jar' -exec jarsigner -keystore ***** -storepass ***** {} \;

Answer 3

find . -iname '*.jar' | xargs jarsigner -keystore ***** -storepass ******
