Is there a way to detect whether sys.stdout is attached to a console terminal or not? For example, I want to be able to detect if foo.py is run via: $ python foo.py # user types this on console OR $ python foo.py > output.txt # redirection $ python foo.py | grep …. # pipe … Read more
I’d like to have a python program alert me when it has completed its task by making a beep noise. Currently, I use import os and then use a command line speech program to say “Process complete”. I much rather it be a simple “bell.”
I see these pretty colors in manpages viewed with less when setting a bunch of these variables. What do they mean, where is the documentation? Is this interpreted by less or termcap?
I would like to configure bash to execute clear command every time I type some command in the terminal (before executing my command). How can I do that?
I use screen for my command-line tasks while managing the servers where I work. I usually run small commands (mostly file-system tasks) but sometimes I run more extensive tasks (like DBA).
Sometimes, a terminal screen is messed up, and when we use man ls to read the manpages, or press the UP arrow to go to previous commands in history, the screen will show characters not as the right place. (for example, treat the end of screen as some where in the middle of the screen).
I have this setup where I have computer with ssh and a display where I have a user logged in to terminal. What I want to do is send commands like I was using that local session with keyboard. I tried to echo to /dev/tty1 but it just shows what I typed instead executing it. Which makes sense. The system only has bash so no GUI or anything like that.
I am looking for an explanation of what happens in Linux when this key combination is pressed to change the current terminal. In particular, what software component intercepts this key combination and changes the terminal? Is it the kernel? If it is the kernel, could you provide the location of the source file which handles this?
I have a bash terminal open. I want to find out whether the option extglob is enabled or disabled in this session, before I change its value. How can I do this?
