Not perfect but working (at least on the project i wrote it ;) )

Specify what you want search in var search, then it grep the folder and show one result at a time.

Press enter and then it will show the next result.

It can work bad on result in the firsts lines, and it can be improved to allow to come back.

But in my case (a large project, i was checking if a value wasn't used withouth is corresponding const and the value is "1000" so there was a lot of result ...) it was perfect ;)

function command_not_found_handle(){ apt-get install $( apt-file search "$1" | grep bin | grep -w "$1" | head -n1 | cut -d ':' -f 1 ) && $* ; }

Work only with bash and apt-file installed.

When it found an unknow command, it will search for a file named "scribus" (in my example), in a folder named bin and then install the corresponding package.

After installation, it will run the command.

Usefull juste after reinstalling linux and missing lot of package.

quota -q $(cat /etc/passwd|cut -d ':' -f 1)
echo Selected $(ls -1 | sort -R | head -n 1)
folder=0;mkdir $folder; while find -maxdepth 1 -type f -exec mv "{}" $folder \; -quit ; do if [ $( ls $folder | wc -l ) -ge 100 ]; then folder=$(( $folder + 1 )); mkdir $folder; fi ; done

If you have a folder with thousand of files and want to have many folder with only 100 file per folder, run this.

It will create 0/,1/ etc and put 100 file inside each one.

But find will return true even if it don't find anything ...

( for((i=0;$i<100;i++))do echo volume $i 1; sleep 0.1s; done; )| mplayer -slave -quiet sample.mp3

Of course, a fifo is required for piloting the fade out of another song, but with a few bash function, we can mix music in bash like :

crossfadeIn > mplayerfifo1 & crossfadeOut > mplayerfifo2

loop 0 10 > mplayer fifo1

etc etc

I often use it at my work, on an ovh server with root ssh access and often have to change mod after having finished an operation.

This command, replace the user, group and mod by the one required by apache to work.

I often use it to find recently added ou removed device, or using find in /dev, or anything similar.

Just run the command, plug the device, and wait to see him and only him

Maybe simpler, but again, don't know how it will work with space in filename.

find $(dpkg -L iptables) -maxdepth 0 -executable -type f

Maybe not clean with big package and too long argument. But return every file who can be executed.
