Stuff about GNU/Linux distro, tips and tricks or information
‘fdupes’ is a handy tool to find and list duplicates file in GNU/Linux or Unix-like operating system.
In Ubuntu you can install fdupes using apt command-line tool
apt -y install fdupes
Usage of fdupes is simple enough, just write:
fdupes -r /path/to/files/
The command will list duplicate files in the “/path/to/files”directory, which is a prime candidate for deletion.
Cronjob or CRON is an important tool to perform automated / schedule task for web application.
Some shared hosting company may limit (or completely disable) the cron service functionality leading to some web application unable to perform periodic / automated task.
Luckily there’s website such as Cron-Job.org which offers free cron-job to those who aren’t able to obtain one.
The best thing about Cron-Job.org service, is they allow minute-by-minute cronjob execution for free!
Bonus: The folks at Cron-Job also releases the source code behind the service at GitHub!
Nmap (or Network Mapper) is probably the most popular network mapper around. However if you are running a very stable long-term support server, there are chances that your nmap database installation isn’t keep up to that.
Updating Nmap database
Nmap detection database consists of these files:
What you need to do is to download these files from Nmap Github project page and copy it to /usr/share/nmap/ folder.
Alternatively, you can use this script ‘nmap-update.sh’ which I’ve created based on this gist.
| #!/bin/bash | |
| wget -N https://raw.githubusercontent.com/nmap/nmap/master/nmap-mac-prefixes | |
| wget -N https://raw.githubusercontent.com/nmap/nmap/master/nmap-os-db | |
| wget -N https://raw.githubusercontent.com/nmap/nmap/master/nmap-payloads | |
| wget -N https://raw.githubusercontent.com/nmap/nmap/master/nmap-protocols | |
| wget -N https://raw.githubusercontent.com/nmap/nmap/master/nmap-rpc | |
| wget -N https://raw.githubusercontent.com/nmap/nmap/master/nmap-service-probes | |
| wget -N https://raw.githubusercontent.com/nmap/nmap/master/nmap-services | |
Copy all the files to /usr/share/nmap/ once all of them have been downloaded.

LLGAL (llgal) is an tool which can automatically generate gallery on your website. llgal is handy if you want to generate photo album out of photos organized in directories/folders.
Running llgal from the console is easy as typing the llgal command at the root directory of your photos.
llgal --exif --li -L -R --title "Album Name" --sx 960 --sy 720 --tx 250 --ty 150
In Ubuntu, the gallery’s theme is located in “/usr/share/llgal/” directory and my customized theme which supports mobile phone can be downloaded here: llgal.zip (mobile enabled)
Personally, i use llgal to generate cctv tiles automatically on my Ubuntu server from which my TP-LINK NC450 and NC250 IP camera uploads through its FTP functions when it detects movements/motion.
llgal can be installed on Ubuntu by running this command
apt -y install llgal
Alternatively you can compile and install llgal directly from its repository

Cracking zip password can be made easy with cracker-ng
Installation is simple, assuming you use Debian, Ubuntu or any other similar operating system :
$ git clone https://github.com/BoboTiG/cracker-ng.git $ cd cracker-ng # For testers and contributors, always work with on the devel branch: $ git checkout devel $ make
Cracking is relatively simple, assuming you have downloaded the awesome Crackstation’s wordlist dictionary.
$ zipcracker-ng -f targetfile.zip -w crackstation-human-only.txt
Additionally zipcracker-ng can also be used with other brute-forcing cracking tool such as john and
$ john --incremental --stdout | zipcracker-ng -f FILE - $ crunch 1 8 -f charset.lst lalpha | zipcracker-ng -f FILE -
I spend most of my time with headless Ubuntu server or Raspbian (a Debian derivatives distro for Raspberry Pi).
So naturally I use ‘nano’ to edit various configurations files and Python Scripts.
Here are several ‘nano’ shortcuts for your references
Searching
Search and Replace
Cut, Copy and Paste
Save and Exit
Indentation (useful for Python)
That’s all which I can share for today…
