Harmful Linux Commands

There is always the good and the bad wherever you go.
The same thing with Linux commands, there are good commands and bad commands as well.

When It comes to bad commands, we find that, the most Linux users who have executed them are newbies who was given wrong directions as help.


Note : don't try to run those commands in your real machine, use Virtualbox if you love testing things.

I'm sure there are other commands which can be used against us.

These commands which I'm going to show are mostly found in forums where a lot of newbies are seeking for help and other online websites targeted at Linux users.


mkfs.ext3 /dev/sda
The command above will delete and erase all Data from the hard disk and format it to ext3.

mv ~ /dev/null
Delete and erase all Data from your root directory by moving them to an invalid directory.

rm -fr /
It is well known command and simplest too. It recursively remove all files from the root.

mv /home/* /dev/null
Moves all home directories to unknown location /dev/null, which means, the home directories with all Its content will be erased.

chmod -R 777 /
This will not cause a physical harm, but It will drive to low security by granting read, write and execute rights on every file to every user on that system.

Find command

Find files under a specified directory that match conditions you specify.

find / -name myfile*

Find files in the root directory and all directories under it that have file names beginning with myfile. The * is a wild-card character that represents any number of characters. The ? is a wild-card character that represents a single character.

find -name '*.pdf' -print -exec chown User2 {} \;

Find all files in this directory and all subdirectories that end with .pdf, display the names of all files that are found on the screen and, for each file (indicated by the curly braces — {}), change its owner to User2.
 The -print option is not necessary, but it is handy to track the progress of the find command. If you do not use -print, the find command is silent except for error messages from find or from chown.

find -name '*.pdf' -exec grep -il 'SOMETHING' {} \;

Find all files in this directory and all subdirectories that end with .pdf and look for the pattern SOMETHING in each of the files. The -i option to grep makes the search case-insensitive. The -l option to grep causes grep to display the names of the files that have SOMETHING in them. When a file is found that contains SOMETHING, this command displays the full path to the file from the current directory (for example,
./home/user/Documents/Linuxcommand.pdf).

Powerful linux terminal emulators

even though Linux Commands isn’t necessary to use in modern desktop Linux distributions, but it is still being used often, with Linux commands or text-based applications you can perform a specific tasks in short amount of time using a terminal, unlike with graphic apps.
Of course because of various tasks that can be performed by text-based applications there are lot of Linux terminal emulators to chose from . here is a list of the most popular and powerful Linux terminal emulators.

Terminator

Terminator

Terminator is considered the best Linux terminal by many user including me. It has a lot of and nice features, it gives the ability to split into small parts inside the main window, drag and drop re-ordering of terminals…
This application is written in Python, and it will work on any other platform with Java.
It means Terminator can be used in Mac Os X, Windows as well, but a little slower .

Gnome terminal

Gnome terminal

It is very used and popular since it is Terminal emulator for the gnome desktop environment, and lot of distributions have it in their desktops such as Ubuntu, Mint, Ferdora …

LXterminal

LXterminal

LXterminal is fast, lightweight, flexible and able to run in all desktop environments.
It is based on Lxde, and compatible with other desktop environments that’s why we see it in many distributions such as Bodhi, ArchBang,Manjaro …

Guake and Yakuake

Yakuake

guake

Guake is used in Gnome environment while Yakuake is used in Kde environment. both adopt the style of the Quake video game, these terminals show up and hide up when using quick keystroke (f12 by default).they are perfect for when you need a terminal quickly to just run a few Linux commands.

Tilda

Tilda

Tilda has the similar style as Guake and Yakuake, it will slide down when you hit some hot key ( F1 by default) but you have more configuration options in Tilda than in Guake and Yakuake. With Tilda you can chose where to put it (position) and you can also edit the size of the terminal window and use some animation effects on Tilda, but, you can’t drag it around on the desktop screen like with other terminals.
