I'm trying to look at some statistics on the size of packages in the Ubuntu repositories, and I'm hoping to sort my searches of packages in the repositories by file size. Is there a command that will let me look at file sizes of packages in the repositories/cache, sort them by file size, etc? `apt-cache stats' doesn't provide all the information I'd like.
I'm interested in only the official repositories at the moment, and I'm interested in sorting all packages in the repositories, not simply the ones I have installed.
答案1
That should work:
apt-cache -f dumpavail | \
egrep '^Package:|^Size:' | \
sed -e 's,Size: ,,' -e 's,Package: ,\n,' | \
awk '{RS=""; FS="\n"} {print $1, $2}' | \
sort -k2 -n
I'm not proud of it but that was done in a bit of a hurry :)

for installed packages you can either use a oneliner:
dpkg-query -W --showformat='${Installed-Size;10}\t${Package}\n' | sort -k1,1n
or third-party tools like wajig:
sudo aptitude install wajig
wajig large
this will give output like
...
libreoffice-core 117,412 installed
google-chrome-stable 136,744 installed
linux-image-3.2.0-23-generic 145,113 installed
linux-image-3.2.0-33-generic 145,872 installed
nvidia-current 179,133 installed
for searches something like this might help:
aptitude search vnc -F "%p %I"
This gives output like:
$ aptitude search xvnc -F "%p %I"
linuxvnc 71.7 kB
linuxvnc:i386 66.6 kB
xvnc4viewer 430 kB
xvnc4viewer:i386 400 kB
the %I shows the "installed" size of the archive. Now you have the ability to use sort to sort the results as you wish.

An alternative to Marcin's solution is this oneliner (only tested in zsh):
apt-cache dumpavail \ | sed -nE '/^(Package|Size):/s/.* //p' \ | while read name; do read size echo $size $name done \ | sort -nr
It has the dubious advantage of only using sed and sort, not also grep and awk. :)
