There are two possible issues there: - sponge doesn't close its stdin before writing to 'file'. This would be a downright error, but easy to check. - the issue with a crash you mention in your article (nicely written articles, BTW -- thanks for them!): well, don't do it on a "precious" file: better keep a copy around. But that would be general sound advice while mucking around with an interactive shell near your data, anyway :-) I don't think I'd use sponge in "real" scripts, but for interactive mucking around and one-offs it still seems handy. And remember, kids -- do your backups :-) Cheers -- t
