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.

The rsstail is the python version (python-rsstail). The final command pipe it on every new line to gammu and a connected phone

rsstail -o -n 1 --f 'RedditQuote: {title}' http://www.reddit.com/r/quotes/new/.rss | while read line; do /usr/bin/gammu --sendsms TEXT +*yournumber* -text "$line"; done

This one is tried and tested for Ubuntu 12.04. Works great for tailing any file over http.

ssh -t HOSTNAME 'tail -f LOGFILE' | while read; do growlnotify -t "TITLE" -m "$REPLY"; done

It will just start playing and will not stop at the point that it has downloaded up to when the video starts

tail -f production.log | perl -ne 'if (/^Completed.in.(\d+)/){$d = int($1/1000);print "\n";$f{$d}++;for $t (sort(keys(%f))){print $t."s: ".$f{$t}."\n"}}'

Commandline perl filter for, using a production.log from a rails app, display on realtime the count of requests grouped by "seconds to complete" (gross round, but fair enough for an oneliner) :)

script -f /tmp/foo will place all output of the terminal, including carriage returns, to a file. This file can be tail dash-eff'ed by one or more other terminals to display the information of the main terminal. Good way to share one's screen on short notice.

Note: This produces a very accurate output, but that includes depending on the size of your terminal to be the same. You can clear screens or even resize the terminal for others using this function; I use it in conjunction with the "mid" command in my list.
