What is Dev pts in Linux?
devpts is a virtual filesystem directory available in the Linux kernel since version 2.1. It is normally mounted at /dev/pts and contains solely devices files which represent slaves to the multiplexing master located at /dev/ptmx which is in turn is used to implement terminal emulators (such as X11 xterm).
What is ssh T option?
ssh(1) -t. OpenSSH SSH client (remote login program) -t Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing menu services. Multiple -t options force tty allocation, even if ssh has no local tty.
What is a pseudo Pty?
A pseudo terminal (PTY) is used to create login sessions or provide other capabilities that require a TTY line discipline. A pseudo terminal consists of two virtual character devices: a master (PTM) and a slave (PTS).
What is difference between tty and PTS?
The difference between TTY and PTS is the type of connection to the computer. TTY ports are direct connections to the computer such as a keyboard/mouse or a serial connection to the device. PTS connections are SSH connections or telnet connections.
How to view stdout for another pts in Linux?
This isn’t exactly obvious, but it redirects the stdout from the process you attached to to the path given in the first line (in this case, your desired pts). The strace tool allows you to get a copy of the output going to a particular file descriptor (in this case, stdout and stderr).
What’s the difference between PTs and TTY in Linux?
/dev/pts is a special directory that is created dynamically by the Linux kernel. The contents of the directory vary with time and reflect the state of the running system. The entries in /dev/pts correspond to pseudo-terminals (or pseudo-TTYs, or PTYs).
What’s the difference between / Dev and / dev / pts?
/dev/pts contains entries corresponding to devices. /dev/pts is a special directory that is created dynamically by the Linux kernel. The contents of the directory vary with time and reflect the state of the running system.
How to get a copy of stdout in terminal?
The strace tool allows you to get a copy of the output going to a particular file descriptor (in this case, stdout and stderr). This will appear in hex dump format. You can detach the rsync process from its terminal and move it to the current one.
