[librecat-dev] fixes and repeatable fields subfields

[Patrick Hochstenbach]

Grep is your friend. The ALEPHSEQ format is great for searching data.

If you have a sorted file with values you want to search like:

search.txt:
aaa
bbb
ccc
ddd
eee

Then you can find out all the MARC records (with 001) where these strings occur with:

$ catmandu MARC to MARC —type ALEPHSEQ < data.mrc | grep -Ff search.txt

ALEPHSEQ is a format that contains for every field in a record a line for text with the ‘001’ record key in front. A great format for searching stuff

Cheers
Patrick
