Sometimes, after updating your Ubuntu Server or running sudo apt-get -f install, you will have a message: 

The link /vmlinuz.old is a damaged link and you may need to re-run your boot loader[grub] 

To solve this warning, run this command: sudo update-grub

My favorite universal text editor in Mac, Windows and Linux is Sublime Text.

Here’s how to install in Ubuntu:

1. sudo add-apt-repository ppa:webupd8team/sublime-text-3
2. sudo apt-get update 
3. sudo apt-get install sublime-text-installer

By default, Google Chrome is not installed in Linux.

Here’s how to install:

• Download the latest current stable version of Google Chrome (64 bit)
  • wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
• Install
  • sudo dpkg -i google-chrome-stable_current_amd64.deb
• In case of any error in the installation, run also this command:
  • sudo apt-get -f install

It is always a good idea to change the default  http://yourhost.com/phpmyadmin to something like http://yourhost.com/yourdb to hide it from easy access to others.

Just edit apache.conf:

sudo nano /etc/phpmyadmin/apache.conf

Change:
Alias /phpmyadmin /usr/share/phpmyadmin

To:
Alias /yourdb /usr/share/phpmyadmin

In some cases that you have hundreds of thousands or even millions of files in a directory that you want to delete, you will encounter this error:
/bin/rm: Argument list too long.

The problem is when you type a command like rm -rf *.* is replaced with the list of all files, and usually, the memory buffer allocated to shell is small to accommodate let’s say millions of file names.

To solve this issue, I usually use this simple command:

find . -type f -delete
