20 Top Most Used & Common SSH Commands

As promised, I will teach babies* to manage unmanaged server from scratch. It means I’ll try to bring those babies from zero to hero being a Server Ninja. Hence, for my early posts I will firstly write all basic things for newbie server admins should know. In this page I list all necessary, most-used and common SSH commands useful to navigate through SSH client like Putty. I believe these commands are working on any Unix-based servers.

* babies = newbies with no knowledge about Linux and server at all

If you are really a newbie, then you should bookmark this page otherwise simply skip this post.

My next plan: I will post other articles of basic guides how to do things in your server via SSH. Browse it all here.

Requirements To SSH

  • A working SSH client like Putty (Windows) or Terminal (Mac and Linux)
  • A working Linux-based server with SSH enabled
  • A cup of coffee if you wish
  • A computer with stable Internet connection

Some Conventions

  1. Hit Enter or Return key on your keyboard after every each command / line
  2. Each line is a single raw of command unless specified otherwise
  3. Replace domain.com with your own domain name and TLD
  4. Replace xxx.xxx.xxx.xxx with IP address of your own server
  5. Replace example paths and file names according to your server information
  6. If a path ends with slash “/” then its a directory
  7. A directory: “/path/to/directory/” will always end with slash “/”
  8. A file: “/path/to/file” won’t have slash “/” in the end
  9. A file is not always having extension in the end of the file name
