If I have a bunch of assorted files, how can I find out their total size?
Quickly is a definite plus, since this will happen hundreds of times.
For example, a list of items comes from
dpkg -L abcde
This can be modified to show just files with
dpkg -L abcde | while read file ; do [[ -f $file ]] && echo $file ; done
How do I find their aggregate size?
See, I'm trying to build a DVR, and I need to uninstall all unnecessary
programs to make more space. The fastest way to do that is to uninstall the
big things first. But, I have to know what they are. I can get a list of
all installed packages with "dpkg-query -l '*' | grep ^ii | tr -s ' ' | cut
-f 2 -d ' '", no problem.
dpkg ... done | du -s
finds the size of ".", du's default directory. No good.
du -s $(dpkg ... done)
finds the size of each file individually. Also no good.
dpkg ... done | xargs du -s
does the same thing as the above when the list is small. I imagine it does
about the same thing when it's large too. Either way, no good.
