Improve your terminal with suggestions from your history with zsh

If you want enable command prediction on your terminal, a good option is to install zsh.

sudo apt-get install zsh 

Now, replace bash by zsh with the following instruction:

USER=`whoami`
chsh -s /bin/zsh $USER

Now, install Oh My Zsh:

sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

And finally install Fish-like autosuggestions for zsh:

git clone http://github.com/zsh-users/zsh-autosuggestions $ZSH_CUSTOM/plugins/zsh-autosuggestions

Edit your ~/.zshrc file and add zsh-autosuggestions as a plugin:

plugins=(git zsh-autosuggestions)

If you like, you can change your terminal theme. I like cobalt2:

git clone https://github.com/powerline/fonts.git
cd fonts
./install.sh

cd ..
git clone https://github.com/wesbos/Cobalt2-iterm.git
cd Cobalt2-iterm 
mv cobalt2.zsh-theme ~/.oh-my-zsh/themes 
vim ~/.zshrc 
ZSH_THEME="cobalt2"

Now, we can restart zshell with the following command:

zsh --


If you want compatibility with your root user, you must do the following steps:

sudo su
sh -c "$(wget https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"
ln -s /home/$USER/.oh-my-zsh /root/.oh-my-zsh 
cd /root/.oh-my-zsh
cp  /home/$USER/.oh-my-zsh/themes/cobalt2.zsh-theme .
mv /root/.zshrc /root/.zshrc.bak
ln -s /home/$USER/.zshrc /root/.zshrc

zsh --

 Now re-login your session

HINT: Probably, when you try to autocomplete in your terminal you would see the following error:

_store_cache:46: permission denied: .oh-my-zsh/cache/DEBS_avail

To solve it just execute this command:

 sudo chown $USER:$USER /home/$USER/.oh-my-zsh/cache/DEBS_avail

Enjoy it!

How to fix Android when developer options are not available for this user

Image
I have an Android One with Oreo version and suddenly my Android rebooted and after that it started to behave strangely: 1) Notification section doesn't work. I can't see notifications from my apps and the arrow and the screw icon to settings access don't work. 2) As I can't access to the notification area, I can't enable Use USB to Transfer Files to access to my phone memory. 3) I can't access to developer mode (I before active it with a lot of taps over Build number). Clicking on developer options just shows developer options are not available to this user. 4) I can't update or install the apps on google play. They freeze on Download pending... message 5) Home and Switch buttons don't work. They light up and vibrate when I tap them but they do nothing. This issue is apparently related to a deconfiguration of user accounts. To fix it, you need re-setup the users. As you can't access to the user manager (you are in guest mode
