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.

Set name of windows in tmux/byobu to hostnames of servers you're connected to

*I run this with byobu as as a custom status bar entry that runs every 10 seconds by putting it in a script here:

.byobu/bin/10_update_windows

There's no output to stdout, so nothing is displayed on the status bar.

*Presumes that #{pane_title} is set to the hostname or prompt containing the host name. In my case, it's in this format:

$USER@$HOSTNAME:$PWD

The sed commands may need to be modified if your pane_title is different.

*If you want to strip out a common part of a hostname, add the following before '| uniq'

-e 's/[COMMON PART]//'

I use that to strip out the domain of the servers I connect to, leaving the subdomain.
