How to write data to existing process’s STDIN from external process?
Your code will not work. /proc/pid/fd/0 is a link to the /dev/pts/6 file. $ echo ‘foobar’ > /dev/pts/6 $ echo ‘foobar’ > /proc/pid/fd/0 Since both the commands write to the terminal. This input goes to terminal and not to the process. It will work if stdin intially is a pipe. For example, test.py is : … Read more
Run interactive Bash with popen and a dedicated TTY Python
This is a solution to run an interactive command in subprocess. It uses pseudo-terminal to make stdout non-blocking(also some command needs a tty device, eg. bash). it uses select to handle input and ouput to the subprocess. #!/usr/bin/env python # -*- coding: utf-8 -*- import os import sys import select import termios import tty import … Read more
How do *nix pseudo-terminals work ? What’s the master/slave channel?
With respect to the master/slave part of your question, from the pty(4) man page (which is referenced from the openpty(3) man page on my system): A pseudo terminal is a pair of character devices, a master device and a slave device. The slave device provides to a process an interface identical to that described in … Read more
How to toggle CR/LF in gnu screen?
onlcr is for translating outgoing newlines to carriage returns. stty -F /dev/ttyS0 inlcr will translate incoming newlines to carriage returns. You can run that from another terminal after starting screen to avoid any resetting that screen may do on startup. Unfortunately however, this will only change the problem. You’ll then get only returns and no … Read more
What does TTY mean in the unix ps command?
A TTY is a computer terminal. In the context of ps, it is the terminal that executed a particular command. The abbreviation stands for “TeleTYpewriter”, which were devices that allowed users to connect to early computers. In relation to your situation, the jar creates a virtual terminal named ‘ttys000’ but the IDE does not attach … Read more
How to workaround “the input device is not a TTY” when using grunt-shell to invoke a script that calls docker run?
Remove the -t from the docker run command: docker run $RUN_ENV_FILE -i –rm –user node -v “$PWD”:/app -w /app yaktor/node:0.39.0 $@ The -t tells docker to configure the tty, which won’t work if you don’t have a tty and try to attach to the container (default when you don’t do a -d).
Can you fool isatty AND log stdout and stderr separately?
Like this? % ./challenge.py >stdout 2>stderr % cat stdout This is a real tty 🙂 standard output data % cat stderr standard error data Because I cheated a little bit. 😉 % echo $LD_PRELOAD /home/karol/preload.so Like so… % gcc preload.c -shared -o preload.so -fPIC I feel dirty now, but it was fun. 😀 % cat … Read more
Get terminal size in Go
I just wanted to add a new answer since I ran into this problem recently. There is a terminal package which lives inside the official ssh package https://godoc.org/golang.org/x/crypto/ssh/terminal. This package provides a method to easily get the size of a terminal. width, height, err := terminal.GetSize(0) 0 would be the file descriptor of the terminal … Read more
Pretend to be a tty in bash for any command [duplicate]
There are a number of options, as outlined by several other Stack Overflow answers (see Caarlos’s comment). I’ll summarize them here though: Use script + printf, requires no extra dependencies: 0<&- script -qefc “ls –color=auto” /dev/null | cat Or make a bash function faketty to encapsulate it: faketty () { script -qefc “$(printf “%q ” … Read more
