Unfortunately, the BulkMibCompile.sh script does not produce a log file unless the output is redirected to a file. For example:
BulkMibCompile.sh -d /global/data/spectrum/MibDatabase.backup --skip_search >> log_file 2>&1
The above with produce a log file called log_file.
Without the ">> log_file 2>&1" at the end, no log file will be produced.
