• check to make sure these are the files indeed that you would like to delete and no other

find /dir/that/contains/esymac_logEvents.log* | xargs ls -l

• Once you verify the first step, execute this command

find /dir/that/contains/esymac_logEvents.log* | xargs rm -f

Since you want to keep all files that differ from the format mentioned, do:

1. Execute this. This will populate FilesToDelete.txt with files/dir to be deleted. Review this to make sure that files listed in are indeed the files you intend to delete.

find /path/to/dir/esymac_logEvents.log* | xargs ls -l > FilesToDelete.txt

2. Once you verify the Step-1, do

find /path/to/dir/esymac_logEvents.log* -type f | xargs rm -f

3. If directories are involved as well that needs to be deleted, Skip 2 and do this instead:

find /dir/that/contains/esymac_logEvents.log* | xargs rm -rf
