Command Line tips and tricks

• For Mac/Linux commands check my other Gist
• I list DOS commands below but it is highly recommended to use the last version of Powershell (version 6+) instead. It began the default command line tool in Windows and provides a wider range of options. Some commands are not supported in Powershell directly. You can use them with cmd /c. For example to use assoc type cmd /c assoc.
• for learning Powershell you can check this article

Using multiple terminal windows

Is is a quite usual use case that you want to use several terminal windows: you work on several different locations, you run different services at the same time without doing it in the background and so on. On typical solution is to use tabs: Mac Terminal has this capability, on Linux you can do it with Gnome Terminal. Other solution is to split the terminal to panes, twux does it for you.

My recommendation is to use two tabs and in one of the tabs open twux panes for services.

Gnome Terminal

command: gnome-terminal

MongoDB

Create and start

• Windows create a mongodb folder in C: (or wherever you want)
  mongod --directoryperdb --dbpath C:\mongodb\data\db --logpath C:\mongodb\log\mongo.log --logappend --rest --install

net start MongoDB - start it with net which is to handle services

Must installs

• Homebrew for command line installs. It is like apt-get in GNU/Linux. Usually there are nextnextfinish install files provided, but from time to time you will need Homebrew. To install a software like wget just type brew install wget
• zsh (brew install zsh), oh my zsh

Other Setup Issues

.bashrc and bash_profile

You should set environmental variables and other preparations Read about .bashrc and .bash_profile here or here, see a good example here
