Recently I come across a nice little nifty tool called parallel ssh (PSSH) to run a single command on multiple Linux / UNIX / BSD servers. You can easily increase your productive with this SSH IT automation tool.

More about pssh

pssh is a command line tool for executing ssh in parallel on some hosts. It specialties includes:

  1. Sending input to all of the processes
  2. Inputting a password to ssh
  3. Saving output to files
  4. IT/sysadmin task automation such as patching servers or looking for error logs
  5. Timing out and more

Let us see how to install and use pssh on Linux and Unix-like system.

You can reuse OpenSSH connections to the same server when you want to open subsequent connections to the same server. For example, if I ran ssh vivek@server42.cyberciti.biz, the ssh client will establish a new SSH connection. It usually takes only a few seconds. However, if I run ssh vivek@server42.cyberciti.biz command again, connecting to a server42.cyberciti.biz multiple times result into the overhead.

This tutorial talks about ssh features called multiplexing that reuse an already-established connection when creating a new SSH session.

Well, that was fast. Touch ID is a fingerprint recognition security feature, designed and released by Apple. It is currently available on the iPhone 5s/6/7 and Macbook pro-2016 editions. Many consider it as a huge security win for the MacBook Pro’s. This sounds amazing feature for command line users.

Say hello to sudo-touchid

sudo-touchid is a fork of sudo with Touch ID support on macOS (powered by the LocalAuthentication framework). Once compiled, it will allow you to authenticate sudo commands with Touch ID in the Terminal on supported Macs (such as the late 2016 MacBook Pros). Since Darwin sources for macOS 10.12 are not available yet, this project is based on sudo sources corresponding to OS X 10.11.6 and obtained from opensource.apple.com.
