Script to merge an authority into another |
| 36 |
parameters : |
| 37 |
\th : this version/help screen |
| 38 |
\tv : verbose mode (show many things on screen) |
| 39 |
\tf : the authority number to merge (the one that can be deleted after the merge). |
| 40 |
\tt : the authority number where to merge |
| 41 |
\tn : don't ask for confirmation (useful for batch mergings, should not be used on command line) |
| 42 |
\tb : batch Merging |
| 43 |
|
| 44 |
All biblios with the authority in -t will be modified to be "connected" to authority -f |
| 45 |
SAMPLE : |
| 46 |
./merge_authority.pl -f 2457 -t 531 |
| 47 |
|
| 48 |
Before doing anything, the script will show both authorities and ask for confirmation. Of course, you can merge only 2 authorities of the same kind. |
