+#!/bin/bash
+
+# This script helps finding the name of the blocks that contain broken math
+# the plugin math_check_online returns the id of the broken blocks
+# this script searches for the block name inside the .tree file
+# this is intended as a temporary solution, it is not elegant
+# how to use this:
+# ./error-find $output-folder $error-block-id
+# $output-folder is where the .tree file is saved
+# $error-block-id does not contain the starting `@-` characters
+# example
+# ./error-find.sh test/Algebra_1-Appunti-out x7t-la0-v5f-j0p
+# with
+# >➜ ls test/Algebra_1-Appunti-out/
+# >0File_principale-coll.json  0File_principale.json  0File_principale.tree
+# >0File_principale.debug      0File_principale.mw    0File_principale_pages
