did upset things. - scripts/schhist2web: backticks in command invocation need quoting - scripts/schhist2web: the change below needs a bashism, so we switch from /bin/sh to /bin/bash - scripts/schhist2web: seems that there's no safe way to use ls -1 in the word list of "for". Use while read ...; ... done < <(ls -1) instead. (We couldn't just pipe this into the while loop, because that would put the loop into a subshell and changes to global variables would thus be lost.)
