Use tee to process a pipe with two or more processes

Tee can be used to split a pipe into multiple streams for one or more process to work it. You can add more " >()" for even more fun.

See multiple progress bars at once for multiple pipes with pv

In this example we convert a .tar.bz2 file to a .tar.gz file.

If you don't have Pipe Viewer, you'll have to download it via apt-get install pv, etc.

Working random fact generator

Though without infinite time and knowledge of how the site will be designed in the future this may stop working, it still will serve as a simple straight forward starting point.

This uses the observation that the only item marked as strong on the page is the single logical line that includes the italicized fact.

If future revisions of the page show failure, or intermittent failure, one may simply alter the above to read.

wget randomfunfacts.com -O - 2>/dev/null | tee lastfact | grep \<strong\> | sed "s;^.*$.*$.*$;\1;"

The file lastfact, can then be examined whenever the command fails.

`pbpaste` | pbcopy

Execute text from the OS X clipboard.

The backtick operator, in general, will execute the text inside the backticks. On OS X, the pbpaste command will put the contents of the OS X clipboard to STDOUT. So if you put backticks around pbpaste, the text from the OS X clipboard is executed.

If you add the pipeline | pbcopy, the output from executing the command on the clipboard is placed back on the clipboard.

Note: make sure the clipboard is text only.

throttle bandwidth with cstream

this bzips a folder and transfers it over the network to "host" at 777k bit/s.

cstream can do a lot more, have a look http://www.cons.org/cracauer/cstream.html#usage

for example:

echo w00t, i'm 733+ | cstream -b1 -t2

hehe :)

This is a working version, though probably clumsy, of the script submitted by felix001. This works on ubuntu and CygWin. This would be great as a bash function, defined in .bashrc. Additionally it would work as a script put in the path.
