create TestFiles for Trying it out in your environment

expireBackups --createTestFiles 30
created 30 test files with extension '.tst' in /tmp
Please try out 
expireBackups --rootPath /tmp --baseName expireBackup --ext .tst --minFileSize 0
then try appending the -f option to the command that will actually delete files (which are in a temporary directory
and run the command another time with that option to see that no files are deleted any more on second run
expireBackups --rootPath /tmp --baseName expireBackup --ext .tst --minFileSize 0
