Check These Out
similar to the previous command, but with more friendly output (tested on linux)
This will enable the possibility to navigate in the history of the command you type with the arrow keys, example "na" and the arrow will give all command starting by na in the history.You can add these lines to your .bashrc (without &&) to use that in your default terminal.
This gives a very rough estimate of how many pages your text files will print on. Assumes 60 lines per page, and does not take long lines into account.
Subtly different to the -n+p method... and probably wrong in so many ways....... But it's shorter. Just.
Downloads Bluetack's level 1 IP blocklist in .p2p format, suitable for various Bittorrent clients.
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

bash.org is a collection of funny quotes from IRC.
WARNING: some of the quotes contain "adult" jokes... may be embarrassing if your boss sees them...
Thanks to Chen for the idea and initial version!
This script downloads a page with random quotes, filters the html to retrieve just one liners quotes and outputs the first one.
Just barely under the required 255 chars :)
Improvment:
You can replace the head -1 at the end by:
$awk 'length($0)>0 {printf( $0 "\n%%\n" )}' > bash_quotes.txt
which will separate the quotes with a "%" and place it in the file.
and then:
$strfile bash_quotes.txt
which will make the file ready for the fortune command
and then you can:
$fortune bash_quotes.txt
which will give you a random quote from those in the downloaded file.
I download a file periodically and then use the fortune in .bashrc so I see a funny quote every time I open a terminal.
Where < target > may be a single IP, a hostname or a subnet
