autossh + ssh + screen = super rad perma-sessions

Only useful for really flakey connections (but im stuck with one for now). Though if youre in this situation ive found this to be a good way to run autossh and it does a pretty good job of detecting when the session is down and restarting. Combined with the -t and screen commands this pops you back into your working session lickety split w/ as few headaches as possible. And if autossh is a bit slow at detecting the downed ssh connection, just run this in another tab/terminal window to notify autossh that it should drop it and start over. Basically for when polling is too slow. kill -SIGUSR1 `pgrep autossh` Show Sample Output
This is sample output - yours may be different.

Kill all processes that don't belong to root/force logoff

explanation: grep -- displays process ids -v -- negates the matching, displays all but what is specified in the other options -u -- specifies the user to display, or in this case negate The process loops through all PIDs that are found by pgrep, then orders a forced kill to the processes in numerical order, effectively killing the parent processes first including the shells in use which will force the users to logout. Tested on Slackware Linux 12.2 and Slackware-current

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Configure second monitor to sit to the right of laptop

You'll need to make sure your xorg.conf permits a virtual screen size this big. If it doesn't then xrandr should return a suitable error message that tells you the required size.

see who's using DOM storage a/k/a Web Storage, super cookies

Someone over at Mozilla dot Org probably said, "I know, let's create a super-duper universal replacement for browser cookies that are persistent and even more creepy and then NOT give our browser users the tools they need to monitor, read, block or selectively remove them!" . This will let you see all the DOM object users in all your firefox profiles. Feel free to toss a `| sort -u` on the end to remove dupes. . I highly recommend you treat these as "session cookies" by scripting something that deletes this sqlite database during each firefox start-up. . note: does not do anything for so-called "flash cookies"

Save an HTML page, and covert it to a .pdf file

Uses htmldoc to perform the conversion

shell function to underline a given string.

underline() will print $1, followed by a series of '=' characters the width of $1. An optional second argument can be used to replace '=' with a given character. This function is useful for breaking lots of data emitted in a for loop into sections which are easier to parse visually. Let's say that 'xxxx' is a very common pattern occurring in a group of CSV files. You could run $ grep xxxx *.csv This would print the name of each csv file before each matching line, but the output would be hard to parse visually. $ for i in *.csv; do printf "\n"; underline $i; grep "xxxx" $i; done Will break the output into sections separated by the name of the file, underlined.

Get a metascore from metacritic.com

This will fetch a metascore from metacritic.com. It requires a url from metacritic without the http://www.metacritic.com/ Example: $ metascore games/platforms/wii/supermariogalaxy - $ metascore tv/shows/marriageref - $ metascore video/titles/newmoon Would be cool to use this in some sort of a graph.

Indent a one-liner.

I often write a one-liner which I want to use later in a script.
