Let's have a look at what occupies these 21 GB in my /dev/sda3.
In Arch Linux, one may use pacman directly to get this information, but there are at least two more convenient ways which lead essentially to the same results:
expac -H M '%m\t%n' | sort -h
or even shorter
pacgraph -c | sort -h
The result of the latter on my system is:
1198MB urbanterror 920MB xonotic 856MB nexuiz 514MB sauerbraten 496MB warsow 486MB texlive-fontsextra 399MB openarena 362MB freecad 280MB quake4 214MB fpc
The extra fonts for TeX is the only package I really need from this top ten of storage hogs.
For more visually oriented users, pacgraph offers an interesting view:
pacgraph -b "#333333" -t "#FFFFFF" -d "#FFFFBB"
I looked closely and discovered mono. WTF do I need mono for?
[cobra@blackvelvet ~]# whoneeds mono Packages that depend on [mono] nant sparkleshare [cobra@blackvelvet ~]# pactree -r -d 1 mono |--mono |--dbus-sharp |--gtk-sharp-2 |--nant |--ndesk-dbus
pacgraph -b "#333333" -t "#ffffff" -d "#ffffbb" -i "#ff0000" "#00ff00" "#0000ff" mono
Ah, sparkleshare! By the way: did I actually install all optional dependencies for sparkleshare?
[cobra@blackvelvet Documents]$ pacman -T $(expac -Q '%o' sparkleshare) python2-nautilus
Naturally not, as I don't use nautilus.
Sparkleshare is located on the AUR and needs to be compiled whenever a new version is released. That's not a problem for my future desktop, which will be distinguished by a very potent CPU. 😄
For a netbook like my Mini, however, the compilation of larger programs takes time and drains the battery. Let's see how many packages on my current desktop are from the AUR:
[cobra@blackvelvet Documents]$ pacman -Qqm | wc -l 64
Too many, if I'd plan to install my system on a netbook! I'm thus still hesitating to install Archbang on my Mini...
And what about the rest, i.e., packages explicitly installed via the official repositories?
[cobra@blackvelvet Documents]$ pacman -Qqe | grep -vx "$(pacman -Qqg base)" | grep -vx "$(pacman -Qqm)" | wc -l 272
The lists with these 336 packages which I have installed in addition to the base system will be very useful for a painless installation of my new system sometime at the end of this year.
