This version works on Mac (avoids grep -P, adding a sed step instead, and invokes /usr/bin/perl with full path in case you have another one installed).

Still requires that you install perl module HTML::Entities ? here's how: http://www.perlmonks.org/?node_id=640489

This function takes a word or a phrase as arguments and then fetches definitions using Google's "define" syntax. The "nl" and perl portion isn't strictly necessary. It just makes the output a bit more readable, but this also works:

If your version of grep doesn't have perl compatible regex support, then you can use this version:

Might be able to do it in less steps with xmlstarlet, although whether that would end up being shorter overall I don't know - xmlstarlet syntax confuses the heck out of me.

Prompts for your password, or if you're a bit mental you can add your password into the command itself in the format "-u user:password".

With counter format [001, 002, ..., 999] , nice with pictures or wallpapers collections.

If you don't have netcat, you can use curl.

I use this with cron to timeshift radio programs from a station's live stream.

You will get an error message at the end like "curl: (28) Operation timed out after 10000 milliseconds with 185574 bytes received"; to suppress that but not other error messages, you can append "2>&1 | grep -v "(28)"" to the end of the command.

Bulk downloads the comic strip JPG files for the adult cartoon Savitabhabhi, storing each set in it's own folder. Requires manual removal of "non-image" files that maybe created because each series may differ in length. The command can be easily adapted for UNIX flavours. You need to have cURL in your path.

An improvement of the original (at: http://www.commandlinefu.com/commands/view/2872/update-twitter-via-curl) in the sense that you see a "from cURL" under your status message instead of just a "from API" ;-) Twitter automatically links it to the cURL home page.

Like the tiltle said, you can use an argument too ( the interface )

will show only the IP of this interface and the public IP

( tested with Linux )

You can add that function in ~/.bashrc, then

Now you are ready to call this function in all your terms...

Requires display.

Corrected version thanks to sputnick and eightmillion user.

Requires the date command. This also works with some other comics. Here's a bash script that displays daily Garfield, Id, and Andy Capp:

http://putnamhill.net/cgi-bin/yahoo-comics.sh?ga,crwiz,crcap

I wasn't sure how to display the image, so I thought I'd try xml for a different twist.

Same thing just a different way to get there. You will need lynx

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:

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:

A function that takes a domain name as an argument

This function uploads images to http://omploader.org and then prints out the links to the file.

Some coloring can also be added to the command with:

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

Not my script. Belongs to mathewbauer. Used without his permission.

This script gives a single line as shown in the sample output.

NOTE: I have blanked out the IP address for obvious security reasons. But you will get whatever is your IP if you run the script.

Tested working in bash.

Yeah I know it's been up here a million times, but this service is a really clean and nice one. Nothing but your IP address on it. Actually I was to write something like this, and noticed this on appspot... ;)

Alternative to the ping check if your firewall blocks ping. Uses curl to get the landing page silently, or fail with an error code. You can probably do this with wget as well.

miss a class at UTOSC2010? need a refresher? use this to curl down all the presentations from the UTOSC website. (http://2010.utosc.com) NOTE/WARNING this will dump them in the current directory and there are around 37 and some are big - tested on OSX10.6.1
