  • Stream the latest offering from your fave netcasts/podcasts

    This is a quick line to stream in the latest offerings of your favorite netcasts/podcasts. You will need to have a file named netcast.txt in the directory you run this from. This file should have one and only one of your netcast's/podcst's url per line. When run the line grabs the offering on the top of the netcast/podcast stack and end it over , quietly, to vlc. Since I move around computers during the day I wanted an easy way to listen to my daily dose of news and such without having to worry about downloading to whatever machine I am on. This is just a quick grab and stream of whats current. Future plans... have the list of netcasts be read from the web. possibly an rss or such. I use greader so there might be a way to use it as the source so as not to have to muck with multiple lists Show Sample Output

  • PlayTweets from the command line

    This will play the audio goodness posted up on PlayTweets via twitter right form the ever loving cmdline. You do not even need a twitter account. I hashed this out in a bit of a hurray as the kids need to get to sleep....I will be adding a loop based feature that will play new items as they come in...after what your are listening to is over. http://twitter.com/playTweets for more info on playtweets Show Sample Output

  • Speak the top 6 lines of your twitter timeline every 5 minutes.....

    Pump up the chatter, run this script on a regular basis to listen to your twitter timeline. This is a rough first cut using several cli clips I have spotted around. There is no facility to not read those things already read to you. This could also easily be put in a loop for timed onslaught from the chatterverse, though I think it might violate several pointsof the Geneva Convention UPDATE - added a loop, only reads the first 6 twits, and does this every 5 mins.

create disk copy over the net without temp files
I wanted to create a copy of my whole laptop disk on an lvm disk of the same size. First I created the logical volume: lvcreate -L120G -nlaptop mylvms SOURCE: dd if=/dev/sda bs=16065b | netcat ip-target 1234 TARGET: nc -l -p 1234 | dd of=/dev/mapper/mylvms-laptop bs=16065b to follow its process you issue the following command in a different terminal STATS: on target in a different terminal: watch -n60 -- kill -USR1 $(pgrep dd) (see http://www.commandlinefu.com/commands/view/4356/output-stats-from-a-running-dd-command-to-see-its-progress)

Convert multiple files using avidemux
Using avidemux to convert multiple files that are in the folder where the command was executed.

Create a persistent connection to a machine
Create a persistent SSH connection to the host in the background. Combine this with settings in your ~/.ssh/config: Host host ControlPath ~/.ssh/master-%r@%h:%p ControlMaster no All the SSH connections to the machine will then go through the persisten SSH socket. This is very useful if you are using SSH to synchronize files (using rsync/sftp/cvs/svn) on a regular basis because it won't create a new socket each time to open an ssh connection.

Checks apache's access_log file, strips the search queries and shoves them up your e-mail
as unixmonkey7109 pointed out, first awk parse replaces three steps.

Get IPv4 of eth0 for use with scripts
Combines wgzhao's grep | awk | sed into one awk command.

Make a directory named with the current date
Create a directory named with the current date in ISO 8601 format (yyyy-mm-dd). Useful for storing backups by date. The --iso switch may only work with GNU date, can use format string argument for other date versions.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Test network speed without wasting disk
The above command will send 4GB of data from one host to the next over the network, without consuming any unnecessary disk on either the client nor the host. This is a quick and dirty way to benchmark network speed without wasting any time or disk space. Of course, change the byte size and count as necessary. This command also doesn't rely on any extra 3rd party utilities, as dd, ssh, cat, /dev/zero and /dev/null are installed on all major Unix-like operating systems.

Look for English words in /dev/urandom
