Hi, A feature request for du, a way to sum from a list of files without doing tr \n \0
I had to sort some files and and needed to know how large the group of files that I had found were. I spend many hours trying to figure this out / and searching for solution. It turns out that the \0 delimited list requirement was very painful. I wish I could cat the output of find into du and get the total btw, my find options included restricting it to type file, http://www.mail-archive.com/[EMAIL PROTECTED]/msg396774.html Geraud suggests a mode for du to to avoid situations like this: Example: $ find <dir> -<options> >files.list # create a NL-separated list of files $ wc -l files.list # wc could not be used to count NUL-separated items # (another more complex program would be needed) $ sed -i -e <expr> files.list # sed is designed for "regular" lines (NL-terminated) $ wc -l files.list $ emacs files.list # editing a NUL-separated list in emacs would be inconvenient $ tr $'\n' $'\0' <files.list >files0.list # an additional command that I would like not to type $ du -csb --from-files0 files0.list | tail -n1 # note the additional tail command that also could be avoided # if there were an option to only display the grand total $ IFS=$'\n' for i in `cat files.list`; do archive "$i"; done # if the list is not too long # does not work with NUL-separated lists (or I do not know how) $ xargs -n1 -d \\n --arg-file=files.list archive # if the list is very long # here files0.list could be used _______________________________________________ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
