My 5Gb /usr partition is full. What do I have installed that's eating up all the space?
Let's see:
#!/usr/bin/ruby
# pkgsizestat - Display the installed size of packages in a filesystem

# Display the installed size of packages in the given filesystem

dev = File.stat(ARGV[0] || "/usr").dev
def pkgsize(name, dev)
size = 0
IO.foreach(name) { |line|
begin
st = File.stat(line.chomp)
if (st.file? && st.dev == dev)
size += st.size
end
rescue
end
}
return size
end
Dir.glob("/var/lib/dpkg/info/*.list").each { |file|
puts "%d %s" % [pkgsize(file, dev), file.gsub(/.+?\/([^\/]+)\.list/, '\1')]
}
Neat little useful ruby script.
Ruby is nice in making scripts short clean and compact. Now I need a shorter version of the GPL :)
Update: Florian Ragwitz suggests to use dpigs(1) from debian-goodies instead. What my script does that dpigs doesn't do, however, is counting only those files provided by the packages that reside in the given partition.
I could for example use my script to see what's filling up the root ('/')
partition when /usr is mounted elsewhere, and I find out that the top package
is not openclipart-svg, but `linux-image-2.6.15-1-686.
Update: htom sent an updated version to sum all sizes and show only up to a certain size:
dev = File.stat(ARGV[0] || "/usr").dev
def pkgsize(name, dev)
size = 0
IO.foreach(name) { |line|
begin
st = File.stat(line.chomp)
if (st.file? && st.dev == dev)
size += st.size
end
rescue
end
}
return size
end
pkgs = {}
Dir.glob("/var/lib/dpkg/info/*.list").each { |file|
pkgs[pkgsize(file, dev)] = file.gsub(/.+?\/([^\/]+)\.list/, '\1')
}
pkgs = pkgs.sort
pkgs.reverse!
to_size = 1024**3 # show up to 1 GB
size = 0
pkgs.each do |a|
size += a[0]
puts "%d %d %s" % [a[0], size, a[1]]
break if size >= to_size
end
Ralph Amissah posted a different variant:
# [License part omitted]
dev=File.stat(ARGV[0] || "/usr").dev
def pkgsize(name, dev)
size=0
IO.foreach(name) do |line|
begin
st=File.stat(line.chomp)
if (st.file? && st.dev == dev)
size += st.size
end
rescue
end
end
return size
end
def space(file,dev)
"%d %s" % [pkgsize(file,dev),file.gsub(/.+?\/([^\/]+)\.list/,'\1')]
end
@used=Array.new
Dir.glob("/var/lib/dpkg/info/*.list").sort.each do |file|
x=Array.new
x << space(file,dev).split(/\s+/)
p [x[0][0].to_i,x[0][1]]
@used << [x[0][0].to_i,x[0][1]]
end
#p @used.sort.each { |x| p x }
@used.sort.each { |x| puts "#{x[0]} #{x[1]}" }
#redirect to file?
Thank you everyone for the nice feedback!
