Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

@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 215 weeks and 3 days 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.
