How to Undo Changes in “nano” Text Editor in Ubuntu

Nano has experimental undo/redo feature. As you’ll see from the nano manual (type “man nano” in a Terminal to read that), you’ll need to start nano with the -u option

 $ nano -u somefile.txt

… and then you can use Alt-U to undo and Alt-E to redo.

It’s little bit frustrating that you have to type the “-u” option every time when you want to edit a file, but hopefully there is a solution and its name is “alias”.

Aliases are a way for you to customize the commands by giving them aliases (nicknames). You can use them to remember commands with a lot of options or make their names shorter and easier to type. To setup aliases, all you need is to open the ~/.bash_aliases file and type in:

alias nano='nano -u'

If you want to add more aliases, enter each of them on separate line.

Now, typing “nano” is equal as typing “nano -u”. Tricky, yeah?


How to setup the perfect LAMP stack on Ubuntu 14.04 LTS

Ok, ladies and gentlemen!

I needed local development server closer as possible to the production one. I downloaded and Installed Ubuntu, but didn’t know how to get Apache, MySQL and PHP installed. After a few hours of reading random blogs found on Google and head banging I succeed.

My requirements was:

  2. Password protect all my subdomains when they are accessed outside my home network but access them directly, without need to provide password, when I am connected to my local network and develop.
  3. To separate the error logs by virtual host (subdomain).

Below is a laundry list of commands to help you configure your own perfect Ubuntu server, too.

How to resolve the “CIFS VFS: Server not responding” error on shutdown

On my laptop I wanted to mount some shared directories (via samba), located on my office network and accessible trough OpenVPN. I need them to work remotely  (there is in my office local development server, used from all my colleagues). Connecting to the VPN and mounting the shares was straightforward. I just have had to install smbfs (Samba file system utilities) and put the following line in my /etc/fstab:

//  /mnt/deals-old  cifs  credentials=/etc/samba/deals-user,noexec,noperm  0 0
