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.

What others think

It didn't work properly for me I used "history -$HISTSIZE" against just "history" to sue the full history and not only the 10th firsts.

my correction is then

history -$HISTSIZE | awk '{a[$2]++}END{for(i in a){print a[i] " " i}}' | sort -rn | head

since i got dates on my commands this one works better for me using the 4th column

history | awk '{a[$4]++}END{for(i in a){print a[i] " " i}}' | sort -rn | head

use this! more portable

history | awk '{a[$'`echo "1 2 $HISTTIMEFORMAT" | wc -w`']++}END{for(i in a){print a[i] "\t" i}}' | sort -rn | head
