What Is “pts/27”?

PT as in pts/27 stands for pseudo terminal session possible in Unix or Linux-based operating systems. In such a system, the PTS are the emulations of real terminals, which are the conventional terminals that characterize old computer systems that users can use to directly interface with the operating system. Some of these PTS devices are for the use of connection like the SSH (Secure Shell) or Telnet, whereby, users can connect to the system from another site.

The number after “pts/” denotes a particular terminal session number of the user which when combined with many others on the system can help determine one particular session. For instance, there is “pts/27” meaning that there occur a series of terminal sessions and the current one is the 27th. Lastly, each active session possesses its PTS device, which enables many users to work with the system concurrently.
