Liked command 4077 so I improved it, by doing all text manipulation with sed. "Run this as root, it will be helpful to quickly get information about the loaded kernel modules." THX mohan43u Show Sample Output
The above code is just an example of printing on the same line, hit Ctrl + C to stop When using echo -ne "something\r", echo will: - print "something" - dont print a new line (-n) - interpret \r as carriage return, going back to the start of the line (-e) Remember to print some white spaces after the output if your command will print lines of different sizes, mainly if one line will be smaller than the previous Edit from reading comments: You can achieve the same effect using printf (more standardized than echo): while true; do printf "%-80s\r" "$(date)"; sleep 1; done
This command creates and burns a gapless audio CD with 99 tracks. Each track is a 30 second sine wave, the first is 1 Hz, the second 2 Hz, and so on, up to 99 Hz. This is useful for testing audio systems (how low can your bass go?) and for creating the constant vibrations needed to make non-Newtonian fluids (like cornstarch and water) crawl around.
Note, this temporarily creates 500MB of .cdda files in the current directory. If you don't use the "rm" at the end of the command, you can burn more disks using
cdrdao write cdrdao.toc
Prerequisites: a blank CD-R in /dev/cdrw, sox (http://sox.sourceforge.net/), and cdrdao (http://cdrdao.sourceforge.net/). I'm also assuming a recent version of bash for the brace expansion (which just looks nicer than using seq(1), but isn't necessary).

why would you want to convert mp3's to ogg? 1 reason is because ardour doesn't support mp3 files because of legal issues. this is really the only reason you would do this, unless you have really bad hearing and also want smaller file sizes, because converting from one lossy format to another isn't a good idea.

This bash function uses albumart.org to find the cover for an album. It returns an amazon.com url to the image.
Usage: albumart [artist] [album]
These arguments can be reversed and if the album name is distinct enough, it may be possible to omit the artist.
The command can be extended with wget to automatically download the matching image like this:
albumart(){ local x y="$@";x=$(awk '/View larger image/{gsub(/^.*largeImagePopup\(.|., .*$/,"");print;exit}' <(curl -s 'http://www.albumart.org/index.php?srchkey='${y// /+}'&itempage=1&newsearch=1&searchindex=Music'));[ -z "$x" ]&&echo "Not found."||wget "$x" -O "${y}.${x##*.}";}

This command lets you select from 10 different BBC stations. When one is chosen, it streams it with mplayer. Requires: mplayer with wma support.
This is useful for paging through long directories, mulitple directories, etc. I put this in my ~/.bash_aliases file and alias 'lsl' to it.

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
This will start the x11vnc server, scale it at 6/7, will use the vncpass file to authenticate and wont shut down as soon as a client disconnects
This will generate a password file to use with x11vnc server, obviously you should replace "your_new_password" with the password you want to use and the path where you want to store it.
