Thought it would be useful to commandlinefuers.

This function displays the latest comic from xkcd.com. One of the best things about xkcd is the title text when you hover over the comic, so this function also displays that after you close the comic.

To get a random xkcd comic, I also use the following:

Sometimes I need a quick visual way to determine if there is a particular server who is opening too many connections to the database machine.

if its the current directory, no need find command. just grep will do

Simply more email-adresses matched

It's not a big line, and it *may not* work for everybody, I guess it depends on the detail of access_log configuration in your httpd.conf. I use it as a prerotate command for logrotate in httpd section so it executes before access_log rotation, everyday at midnight.

This is a bit of a hack, but it will get your fwguid which is needed sometimes when using your iPod.

Must have the video open and fully loaded.

I know this has been beaten to death but finding video files using mime types and printing the "hours of video" for each directory is (IMHO) easier to parse than just a single total. Output is in minutes.

Among the other niceties is that it omits printing of non-video files/folders

PS: Barely managed to fit it within the 255 character limit :D

Uses mime-type of files rather than relying on file extensions to find files of a certain type.

This can obviously be extended to finding files of any other type as well.. like plain text files, audio, etc..

In reference to displaying the total hours of video (which was earlier posted in command line fu, but relied on the user having to supply all possible video file formats) we can now do better:

Substitute feh for the image viewer of your choice. display (part of imagemagick) seems to be a popular choice.

midentify.sh is part of mplayer, but you might have to locate it on your box.

You'll be notified if your core 1 temperature exceeds 50 degrees, you can change the monitored device by editing the "Core 1" or change the critical temperature by editing the "-gt 50" part.

Note: you must have lm-sensors installed and configured in order to get this command working.

I have a custmer's Geovision DVR installed on a closed proxi (only logme-in reaches it).

I have to check for reliability but logmein hangs and is too slow a process

I made the Geovision software send e-mail every minute to the www.spam.la site.

All this script does is to retrieve the e-mail header from spam.la ( no login!), filtering sender, stopping at the first occurrence of the word "secs" ( the age of the last e-mail ).

The result is the age of the sender's last e-mail, tiny published on top of my screen once a minute.

I can refresh www.spam.la via web browser, but have other things to do.

I use it inside Kalarm ( kde task schedule ) set to 1 minute repeat.

It can be done without kalarm, using Watch outside the script.

Try it out now using my account = geo1 ( change sender by geo1 in this script)

Needs curl , osd-bin

handles file names with spaces and colons, fixes sort (numeric!), uses mplayer, same output format as other alternatives

Similar but using mediainfo instead of totem-something

Sort .avi movies by time length, print the longest first, and so on...

That makes a function you can put in your ~/.bashrc to run it when you need in any term with an IP as argument

...or for a particular interface...

Extracts the model name of the CPU and displays it on screen.
