A web server using $HOME/public_html as user directory is required, $HOME/public_html/shots must exist and have appropriate access rights and $HOSTNAME must be known to and accessible from the outside world.

The command uses scrot to create a screen shot, moves it to the screen shot directory, uses xsel to copy the URL to the paste buffer (so that you can paste it with a middle click) and finally uses feh to display a preview of the screen shot.

Assign this command to a key combination or an icon in whatever panel you use.

Generate the iso from the disk, easily.

same as "dd if=/dev/cdrom of=~/mydisk.iso"

Have netcat listen on port 8000, point browser to http://localhost:8000/ and you see the information sent. netcat terminates as soon as your browser disconnects.

I tested this command on my Fedora box but linuxrawkstar pointed out that he needs to use

instead. This depends on the netcat version you use. The additional '-p' is required by GNU netcat that for example is used by Debian but not by the OpenBSD netcat port used by my Fedora system.

'watch' repeatedly (default every 2 seconds, -n 1 => every second) runs a command (here ':', a shorthand for 'true'), displays the output (here nothing) and the date and time of the last run.

I thought it to be obvious but it seemingly is not: to exit use Ctrl-C.

explanation:

grep -- displays process ids

-v -- negates the matching, displays all but what is specified in the other options

-u -- specifies the user to display, or in this case negate

The process loops through all PIDs that are found by pgrep, then orders a forced kill to the processes in numerical order, effectively killing the parent processes first including the shells in use which will force the users to logout.

Tested on Slackware Linux 12.2 and Slackware-current

Replace "url" with the correct address of what your're downloading. Replace 01:00 with what time you want. (24-hour clock).

By 'pst' you can print out process tree with all details about all processes (including a command line, PID, and the current process you are running in).

By 'pst username' you can get an information about processes belonging to the particular user 'username'.

Ever had a file with a list of numbers you wanted to add, use:

* size must be 640?480 pixels

* only has 14 colors

* save it in XPM format

Edit /boot/grub/menu.lst and add

splashimage=(hd0,0)/boot/grub/grubimg.xpm

make sure for your path name and hard disk

NOT MINE! Taken from hackzine.com blog.

It creates a tree-style output of all the (sub)folders and (sub)files from the current folder and down(deeper)

Quoting some of hackzine's words

"Murphy Mac sent us a link to a handy find/sed command that simulates the DOS tree command that you might be missing on your Mac or Linux box. [..split...] Like most things I've seen sed do, it does quite a bit in a single line of code and is completely impossible to read. Sure it's just a couple of substitutions, but like a jack in the box, it remains a surprise every time I run it."

cd into the directory that contains the file.

this is just the usual move command but shortcut'd.

say you wanted to move a photo img1.png from ~/photos/holidayphotos into the parent directory which is ~/photos

command would be:

~/photos/holidayphotos$ mv img1.png ..

I use Ubuntu so this'll work in debian but not sure what else.

Suppose you made a backup of your hard disk with dd:

dd if=/dev/sda of=/mnt/disk/backup.img

This command enables you to mount a partition from inside this image, so you can access your files directly.

Substitute PARTITION=1 with the number of the partition you want to mount (returned from sfdisk -d yourfile.img).

The large context number (-C 1000) is a bit of a hack, but in most of my use cases, it makes sure I'll see the whole log output.

This is useful if you have a program which doesn't work well with multicore CPUs. With taskset you can set its CPU affinity to run on only one core.

I use this command on my machines running VMware Server to print out the state of all registered Virtual machines.
