Requires: signing-party (on Debian).

Note: you need a working MTA on your machine.

For vi(m) users :

Add it in your ~/.bashrc

Add an "exit" @ the end if you are masochist ;)

the result of the command helped a check the Maximum file size and Maximum file system size.

EXT3 Exemple:

Block size; MAX File size; Maximum file system size

1 KiB; 16 GiB ; 2 TiB

2 KiB ; 256 GiB ; 8 TiB

4 KiB ; 2 TiB ; 16 TiB

8 KiB[limits 1]; 2 TiB; 32 TiB

Streams your timeline on the commandline, required fbcmd

https://github.com/dtompkins/fbcmd

The shell has perfectly adequate pattern matching for simple expressions.

VARNAMES='ID FORENAME LASTNAME ADDRESS CITY PHONE MOBILE MAIL ...'

cat customer.csv | while read LINE ; do

COUNT=1

for VAR in $VARNAMES ; do

eval "${VAR}=`echo $LINE | /usr/bin/awk {'print $'$COUNT''}`"

let COUNT=COUNT+1

done

done

Maybe you have a CSV-File with addresses, where you have to process each contact (one per line, write each value to own variable). Of course you can define every variable, but this way is more simple and faster (to write).

VARNAMES includes the variable names. Pay attention: the number of names in VARNAMES have to be the same than in the CSV-file the fields. If the CSV is not seperated with ";", you can set the seperator after the awk-binary with -F"_" for example.

some other options:

&delay=1000

&mode=links

much more with piggybank as scraper

works well with your favourite curses or non-curses http clients

was inspired by http://www.commandlinefu.com/commands/view/8936/boot-from-a-block-device-without-giving-root-privilege-to-virtual-box

volpedimongibello= virtual machine name

fighetto= controller name

tutto.iso= DVD iso image

How to remove the DVD:

VBoxManage storageattach "volpedimongibello" --storagectl "fighetto" --port 1 --device 0 --type dvddrive --medium none

When you need to work a long time in the same directory, which prompt is of the type:

[email protected]:~/directory1/directory2/directory3/directory4/directory5$

it is better to hide all this with the command PS1='$'

To retrieve a normal prompt, type: PS1='$PWD$ '

sudo pmset -a hibernatemode 1 sets hiberate on.

sudo pmset -a hibernatemode 0 sets hibernate off.

from the pmset man page:

0001 (bit 0) enables hibernation; causes OS X to write memory state to

hibernation image at sleep time. On wake (without bit 1 set) OS X will

resume from the hibernation image. Bit 0 set (without bit 1 set) causes

OS X to write memory state and immediately hibernate at sleep time.

I often change my MacBook's sleep state. So I created a function for bash to make it a little easier.

Usage:

hibernate (on | off)

"hibernate on" will set your laptop to hibernate if the lid is closed.

"hibernate off" will set your laptop to sleep if the lid is closed.

### note : "proper" indentation isn't preserved on the website

function hibernate()

{

case "${1}" in

on)

sudo pmset -a hibernatemode 1

echo Hibernate mode on.

;;

off)

sudo pmset -a hibernatemode 0

echo Hiberate mode off.

;;

*)

echo "I'm sorry Dave, but I can't do that."

;;

esac

}

To make things easier, add the proper line in your /etc/sudoers file so that your user may invoke pmset without a password. Here's how mine looks:

bwayne luna = NOPASSWD: /usr/bin/pmset

Don't forget that you must edit sudoers with `sudo visudo` from Terminal.app, and not by another text editor.

Sorry this is so Mac OS specific.

Bulk downloads the comic strip JPG files for the adult cartoon Savitabhabhi, storing each set in it's own folder. Requires manual removal of "non-image" files that maybe created because each series may differ in length. The command can be easily adapted for UNIX flavours. You need to have cURL in your path.

This must be run the first time while logged into your Mac desktop, as it will graphically prompt for access permissions. Subsequent uses will not prompt, assuming you select "Always allow".

Counts Mysql Threads

mysql switches

-N skip column names (remove headers)

-s silent mode (removes separator chars)

-r raw output

-e execute

grep switches

-c count lines

-v invert match (match all except)

Very useful for finding all the source code that should be compiled.

Here $HOME/shots must exist and have appropriate access rights and sitecopy must be correctly set up to upload new screen shots to the remote site.

Example .sitecopyrc (for illustration purposes only)

site shots

server ftp.example.com

username user

password antabakadesuka

local /home/penpen/shots

remote public_html/shots

permissions ignore

The command uses scrot to create a screen shot, moves it to the screen shot directory, uploads it using screen 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.

Note that $BASE stands for the base URL for the screen shots on the remote server, replace it by the actual location; in the example http://www.example.com/~user/shots would be fitting.

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

awk extract every nth line.

Generic is:

awk '{if (NR % LINE == POSITION) print $0}' foo

where "last" position is always 0 (zero).

You must spezify /where folder and / folder

If you have another camera you must experiment with Exif data (after -g and after grep) and mask of your photo files IMG_????.JPG

I have do it on Knoppix 6.7.0

You must have installed exiv2.

you can use a pair of commands to test firewalls.

1st launch this command at destination machine

then use this command at source machine to test remote port

First command will listen at specified port.

It will listen TCP. If you use -u option will listen UDP.

Second command will send "foo" through ncat and will reach defined IP and port.

This command prints all lines of a file together with is line number.
