Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

@TheMightyBuzzard: I tested both commands under OS X and found kayowas' version more accurate: It correctly handles command such as:

ls|grep "foo"

where the pipe symbol immediately follows the command.

Comment by haivu 424 weeks and 1 day ago

I bet "cd" and "ls" will be the top commands in most of our readers lists ;)

I think awk '{print $1}' approach is not accurate for counting commands in pipes. So, I propose the following(*) for the most accurate counting:

....|perl -F'\|' -ane 'foreach $pipe (@F) {$pipe=~ /\s*(\w+?)\s/;print $1,"\n";} ' | sort | uniq -c | sort -nr | head

Below is comparison of top 10 commands

My method kayowas' method

1023 sudo 1003 sudo

970 perl 894 cd

904 cd 657 nano

668 nano 617 perl

624 awk 593 ls

601 ls 498 cat

601 grep 351 history

569 cat 293 man

499 cut 284 head

457 head 276 find

(*) print history without the line numbers

sorry, spaces and tabs are lost, i'm posting the results again:

My method ----- kayowas' method

1023 sudo --- 1003 sudo

970 perl ----- 894 cd

904 cd ------- 657 nano

668 nano ----- 617 perl

624 awk ------ 593 ls

601 ls ------- 498 cat

601 grep ----- 351 history

569 cat ------ 293 man

499 cut ------ 284 head

457 head ----- 276 find

Notice absence of awk, cut and grep in kayowas' method.
