Apt-fast

Speed-up APT packages downloading with 'axel' (light command line download accelerator). Juste use it like aptitude/apt/apt-get.

sudo apt-fast full-upgrade

Bash_quote

Get a random quote from http://danstonchat.com with 'lynx'.

Droopy

Run a small webserver and allow user to upload files to a local directory:wq

### Firewall A shell script to apply some Iptables rules.

• Rules are automatically apply only for the UP interfaces.
• If it's detect some softwares (eg. Apache2), Iptables rules for ports 80/443 are automatically apply.
• Special rules allow all traffic throught a VPN:

firewall vpn

• If a local file exists (firewall.local) it will also apply it. For personnal rules for example.

Flac_to_mp3

Convert FLAC audio files to MP3 with 'avconv'.

• Convert a directory:

flac_to_mp3 /media/data/bisounours_land_v2

• Convert a file:

flac_to_mp3 /media/data/makarena.flac

Num_circle

Tiny Bash script that take a number between 0 and 20 as argument and transform it into a digit with into a circle.

Pomodoro

My implementation of the Pomodoro Technique (https://en.wikipedia.org/wiki/Pomodoro_Technique).

You can simply launch it with:

pomodoro "Work my french kiss"

Then the script will:

• Create a ~/.pomodoro directory to store current task (current.task) and a summary of each week (eg week-42-2015.txt).
• First, it's put task name and a timer (for $WORK_TIME) to the current task file.
• Once the $WORK_TIME has been reached:
  1. Log task name and worked time to the weekly log file
  2. Toggle the sound to mark a pause
  3. It's put a pause/break message for 5/20 minutes as current task
  4. Delete the current task file

Disavantages

• Must run the script every ~30 minutes
• …?

Advantages

• I can display my current task and it's timer wherever i want (tmux, herbstluftwm, …)
• Written to work with /bin/sh

Test_ssl3

Redhat's script to test if an LDAP server support SSLv3.

You could also use a nmap command:

nmap --script ssl-enum-ciphers -p 443 ldap.tld.org | grep "SSLv3: No supported ciphers found"

Weblink

Python program that run a small webserver (BaseHTTPServer) to easily share some files.

• eg:

weblink /tmp/goodbye.file
HTTP server running at http://localhost:8888/
^C^C received, shutting down server

• With a password:

weblink --pass=die /tmp/kitty.file
HTTP server running at http://localhost:8888/die
