Look about halfway down for 's' and 'S'. I did: The expression is a sed-like replace expression of the form: s/regexp/replace/[flags] Supported flags are: ‘g’ Apply the replacement to all matches to the regexp, not just the first. In addition, several transformation scope flags are supported, that control to what files transformations apply. These are: ‘r’ Apply transformation to regular archive members. Where do you get "flags go at the start?" from that? The s at the start (lower case, not upper case) is the sed search-and-replace command, not a flag. The S I was talking about is the flag: ‘S’ Do not apply transformation to symbolic link targets. (Specifying _any_ of the lower case srh seems useless because they're the default, you'd only use them after an SRH to undo it again and... why? There's no P to not print after a p... No G to say "I didn't really mean to say global, actually just do the first one"...) I've tried to find an example of anyone actually USING the select-by-filetype flags with tar transform, and so far have not managed to. Do you have an example? (Could you get it to work?) Also, why doesn't --strip apply equally to create and extract? Why does the --show-transformed option exist? (Why would you NOT show the names you're using? You can always cat "tar.tar | tar t | tar x --transform" if you want the output NOT to match what it's actually doing, why would you make it the DEFAULT?) This whole feature does not appear thought out. (Oh hey, there's a -P option to disable stripping / off the start of extracted names. Maybe I should implement that? I wonder if that also disables the ../../.. stripping? It doesn't say. Time to test!) And again, why a --show-stored-names if it's the default? There isn't an "rm -r --do-not-recurse". How does this HELP? Rob _______________________________________________ Toybox mailing list [email protected] http://lists.landley.net/listinfo.cgi/toybox-landley.net
