Need to write a script in UNIX to find a file if another file exists
So I have a lot of Java applications on my servers all having their own folder from the applications subdirectory. Now, I need to do the following.

Search all the applications subdirectories for message.jar.

If the message.jar file exists, I need to search the application directory for license text.

For example, my application subdirectory consists of the following application folders.

application/messagingApp/
application/databaseApp/
application/toolsApp/

Now when I run the following command from :/application:

:/application % find . message.jar -print

I get the following:
application/messagingApp/common/jars/message.jar
application/toolsApp/jars/message.jar


Now, since I know that the messagingApp and toolsApp contains message.jar, I now need to search all files in the directory (subdirectories don't have to be searched) application/messagingApp and application/toolsApp for the
following text: licenseKey=, and if it doesn't exist, I need to know what the application folder is.

For example, application/messagingApp/licensing.prop contains licenseKey= but there is no file in application/toolsApp that contains licenseKey= and toolsApp should be the output of the program.

CREATE-JAR-LINKS(1)						   User Commands					       CREATE-JAR-LINKS(1)

NAME

       create-jar-links -f instructions_file [-a archive_file] [-p]

SYNOPSIS

       create-jar-links -f instructions_file [-a archive_file] [-p]

OPTIONS

       -a Archive file on which actions will be performed, as opposed to current directory

       -p Preserve original file names (-p to build-jar-repository)

       -f The instructions file to check against.

       -a Archive file on which actions will be performed, as opposed to current directory

       -p Preserve original file names (-p to build-jar-repository)

       -f The instructions file to check against.

EXAMPLES

       Suppose	there  is a clean source tarball (using clean-binary-files(1) and check-binary-files(1)). Following this, one can extract the tar-
       ball, cd to it, and run:

	      create-jar-links -f <instructions> -d <custom_jar_map>

       This would call build-jar-repository(1) and create symlinks, with extra mappings (form vanilla jar names to jpp names) that are specifiable
	      via the custom jar map.

SEE ALSO

   Regular Manual Pages
       check-binary-files(1), create-jar-links(1), build-jar-repository(1), jpackage-utils(7)

   Documentation
       Further reading should be found in clean-binary-files.txt located in your standard documentation directory.
