Subject: Add --since option to marc_export cl script
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=544eff8730030109e55c95f1449b30f59f5eaf5a;p=working%2FEvergreen.git

Add --since option to marc_export cl script

It's useful to be able to export records from a certain
creation or edit date.
1) We have workflows that require periodic record exports
2) Makes testing quick and easy

Only works with the --all flag

Example: marc_export --all --since=$(date -d '2 months ago' +%Y-%m-%d)
Example: marc_export --all --edited --since=$(date -d '2 days ago' +%Y-%m-%d)
