Option | Param | Description | |
--cache | dir | Define a directory for a SZS cache. If creating a YAZ0 compressed file with standard compression (level 9), the cache is searched for the compressed version. File cache-content.txt is used as file list with hash values. If the cache file is not found or the content differ, the file is (re-)created and exit status 2=differ is returned.
Background: Loading a compressed SZS and content verification is much faster than YAZ compression. For legay reasons: If parameter DIR is a file, it is split into directory and base name. The directory is used for the cache directory and the base name for option --cname, but only if --cname is not used. |

--log-cache | file | Define a file to log chache activities. The file is openend in append-mode. | |
--purge | Remove repeated files with same checksum. | ||
--fast | Scan 'cache-content.txt' and remove duplicates. Ignore option --purge. |
