Get size of each installed formula in homebrew? [closed]

Question

I would like to find the size of my installed brew packages so I can see how much space each is taking up. How do I go about doing this from the terminal?

Note: some of the answers below also include brew cask packages which is also very helpful to this answer.

Answer 1

riffing off of PTao's solution, here's an ugly improved version which will include a human-readable sum of the combined sized of all package versions

for pkg in `brew list --formula -1 | egrep -v '\.|\.\.'`   do echo $pkg `brew info $pkg | egrep '[0-9]* files, ' | sed 's/^.*[0-9]* files, \(.*\)).*$/\1/' | awk '{print $1;}/[0-9]$/{s+=$1};/[mM][bB]$/{s+=$1*(1024*1024);next};/[kK][bB]$/{s+=$1*1024;next} END { suffix=" KMGT"; for(i=1; s>1024 && i < length(suffix); i++) s/=1024; printf "\t(all versions: %0.1f%s)",s,substr(suffix, i, 1), $3; }'` done 

example output:

ack 173.5KB 178.4KB 182.7KB 190.5KB (all versions: 725.1K) afl-fuzz 556.5KB 561.3KB (all versions: 1.1M) aircrack-ng 934.2KB 953KB (all versions: 1.8M) autoconf 1.9MB (all versions: 1.9M) autojump 325.4KB (all versions: 325.4K) automake 2.9MB 3.0MB 3MB (all versions: 8.9M) bash-completion 608.6KB (all versions: 608.6K) boost 414.6MB 398.7MB (all versions: 813.3M) cairo 5.9MB 5.9MB (all versions: 11.8M) cask 166.6KB (all versions: 166.6K) cmake 31.4MB (all versions: 31.4M) coreutils 8.5MB 7.9MB 9MB (all versions: 25.4M) curl 3MB (all versions: 3.0M) dos2unix 344.4KB 360.5KB (all versions: 704.9K) ebook-tools 69.6KB 70.5KB (all versions: 140.1K) eigen 3.5MB 6.5MB (all versions: 10.0M) 

Answer 2

It's not exceedingly pretty, but you can do

$ brew list --formula | xargs brew info 

And it will output something along the lines of

... /usr/local/Cellar/ant/1.9.6 (1,611 files, 34.8M)   Poured from bottle on 2016-03-31 at 09:35:41 /usr/local/Cellar/ant/1.9.7 (1,611 files, 34.9M) *   Poured from bottle on 2016-12-15 at 09:58:56 .. 

for each package you have installed. I'm sure some wizard with grep could make this give you a nice table if you have many taps installed.
