Tuned for short command line - you can set the path to sessionstore.js more reliable instead of use asterixes etc.

Usable when you are not at home and really need to get your actual opened tabs on your home computer (via SSH). I am using it from my work if I forgot to bookmark some new interesting webpage, which I have visited at home. Also other way to list tabs when your firefox has crashed (restoring of tabs doesn't work always).

This script includes also tabs which has been closed short time before.

And then to complete the task:

Go to target host;

Turn everything off:

Create duplicate config:

Yeah, there are many ways to do that.

Doing with sed by using a for loop is my favourite, because these are two basic things in all *nix environments. Sed by default does not allow to save the output in the same files so we'll use mv to do that in batch along with the sed.

With this command you can use shell variables inside sed scripts.

This is useful if the script MUST remain in an external file, otherwise you can simply use an inline -e argument to sed.

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:

which will separate the quotes with a "%" and place it in the file.

and then:

which will make the file ready for the fortune command

and then you can:

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.

Simple but useful command, I use this for purge an hard disk entry in Virtualbox registry file (is in ~user/.Virtualbox) that persist if I erase a Virtual Machine, so I need to delete it manually.

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.

This command might not be useful for most of us, I just wanted to share it to show power of command line.

Download simple text version of novel David Copperfield from Poject Gutenberg and then generate a single column of words after which occurences of each word is counted by sort | uniq -c combination.

This command removes numbers and single characters from count. I'm sure you can write a shorter version.

G option cause a file to be spacing line by line.

Ok so it's rellay useless line and I sorry for that, furthermore that's nothing optimized at all...

At the beginning I didn't managed by using netstat -p to print out which process was handling that open port 4444, I realize at the end I was not root and security restrictions applied ;p

It's nevertheless a (good ?) way to see how ps(tree) works, as it acts exactly the same way by reading in /proc

So for a specific port, this line returns the calling command line of every thread that handle the associated socket

This works just like write or wall ... cept one thing the sender is anonymous ... if you really want to drive everyone insane replace echo \"The Matrix has you...\" with cat /dev/urandom

nice one to do on April fool's day

use today's time stamp to make a unique directory for today or an hour ago ...

Useful for switching over someone else's coding style who uses camelCase notation to your style using all lowercase with underscores.

A powerfull way to rename file using sed groups.

& stand for the matched expression.

\1 referes to the first group between parenthesis. \2 to the second.

url can be a working copy or url to a svn repository, revision is any valid revision number for that branch.

This command puts all the flags of the USE variable actually used by the packages you emerged to the file "use", and those which are unused but available to the file "notuse"

If you're like me and want to keep all your music rated, and you use xmms2, you might like this command.

I takes 10 random songs from your xmms2 library that don't have any rating, and adds them to your current playlist. You can then rate them in another xmms2 client that supports rating (I like kuechenstation).

I'm pretty sure there's a better way to do the grep ... | sed ... part, probably with awk, but I don't know awk, so I'd welcome any suggestions.

After every line in targetfile (empty lines included) insert in a line from addfile. "Save" results to savefile. Addfile should be longer than targetfile since this doesn't loop back to the top of addfile.

/^/R addfile -- says for every line that matches "has a start of line" output a line from the file addfile.

> savefile (optional) -- redirect output to savefile file.
