The unlock command for KDE 4.3 has changed from krunner_lock, this process doesn't exist anymore. So here's the update :-)

If qdbus complains about not being able to find X, put a "DISPLAY=:0 " (:0 being your X server display) in front of the command.

'jot' does not come with most *nix distros, so we need to use seq to make it work. This version tested good on Fedora 11.

Stop tormenting the poor animal cat!

Also you should not that you need a private key not protected by a passphrase on middlehost that grants you access to securehost..

Debian: Mark all dependent packages as manually installed. So they are not automatically removed if you remove some meta package - like gnome-desktop-environment for example.

By using vim, you can also filter content on stdout, using vim's extra power, like search pattern offset!

No more awk of course, sorry.

-s silent

-c 'ex command' : global + start and end pattern + offset print (p)

If you need to ssh into a computer on the local network but you're unsure of the ip to use, then ping them and see if you get a response. If you do, print out the address you got it from. Adjust the range to suit your network.

Nice little alarm clock to wake you up on time (hopefully).

You can also do 'echo "vlc path/to/song" | at 6:00

In the vein of "can you do it better", here is my take on using "ping" to emulate sleep in a DOS/BAT script. If one can use ping at all then the multicast address will be valid but will not respond. By doing only one ping (-n 1) and setting a timeout in milliseconds (-w 10000) you have a fairly accurate timer. This example gives about a 10 second sleep.

This is an extension of a previous command by satyavvd on 2009-07-23 12:04:02, but this one grabs the whole archive. Hard coded numbers in previous script capped number of commands that could be fetched. This one grabs them all regardless of how big the archive gets.

"&&" runs sed if and only if the backup completed and /bin/cp exited cleanly. Works for multiple files; just specify multiple filenames (or glob). Use -v switch for cp to play it safe.

this command works with one gziped file per table, and restore 4 tables in parallel.

this works on Solaris, so not better than the "only-GNU"-tool :-(

I think, there is no one-liner for this, that will work on all *nix-es

- convert unixtime to human-readable with awk

- useful to read logfiles with unix-timestamps, f.e. squid-log:

sudo tail -f /var/log/squid3/access.log | awk '{ print strftime("%c ", $1) $0; }

middlehost allows ssh access from where you are but not securehost.

Use nice ssh piping to simulate scp through A => B => C

setting up the shell function if left as an exercise for the reader. ;-)

Agent forwarding should avoid password typing.

Uses the data in the /proc system, provided by the acpid, to find out the CPU temperature. Can be run on systems without lm-sensors installed as well.
