Not sure whether this is faster but it’s shorter:

dirs = Hash.new do |h,dir|  
Dir.chdir dir { system ‘git pull’ }  
h[dir] = true  
end

Dir[File.join(File.expand\_path(“~/programming/repos”), “\*\*”,  
“\*.git”)].each do |gf|  
dirs[File.basename(gf)]  
end

Alternative

require ‘set’

dirs = Set.new

Find.find File.expand\_path(“~/programming/repos”) do |f|  
dir = File.dirname f

if File.file? f and /.git$/ =~ f and dirs.add? dir  
Dir.chdir dir { system ‘git pull’ }  
end  
end
