History Meme
By chris on April 16th 2008 in /dev/random | 921 views
Jumping on the shell command history meme:
history|awk '{a[$2]++} END{for(i in a){printf “%5d\t%s \n”,a[i],i}}’|sort -rn|head
97 ruby 64 cd 45 telnet 43 ss 27 sudo 25 ping 25 mysql 18 ll 16 svn 11 script/generate
Too much playing in Ruby, I think!
Interestingly, this variant:
history|awk '{print $2}'|sort|uniq -c|sort -rn|head
Produces a slightly different count for Ruby:
95 ruby 64 cd 45 telnet 43 ss 27 sudo 25 ping 25 mysql 18 ll 16 svn 11 script/generate
Tag, you’re it.

Its different in each of my sessions, but this is typical.
history 1 | ruby -e ‘h=Hash.new(0); while gets; h[$_.split[1]]+=1 end; h.map{|k,v| [v,k]}.sort.reverse.each{|v,k| puts “%4d %s”%[v,k]}’
