terminal

问题 Apparently I've done something strange/wrong in a tcsh shell, and now whenever I start an application in the background which prints to stdout the application is suspended (stopped). Weird thing is, this behavior only happens in this terminal; if I do the same in another terminal, the application just keeps running in the background and prints it output to the terminal. In the "broken" terminal I have to put the suspended application back into foreground (with fg ) to have it continue.

问题 Is there any reliable way of getting the number of columns/rows of the current output terminal window? I want to retrieve these numbers in a C/C++ program. I'm looking for a GNU/Linux solution primarily, but also need a Windows solution. 回答1: For Unix(-based), use ioctl(2) and TIOCGWINSZ : #include <sys/ioctl.h> //ioctl() and TIOCGWINSZ #include <unistd.h> // for STDOUT_FILENO // ... struct winsize size; ioctl(STDOUT_FILENO, TIOCGWINSZ, &size); /* size.ws_row is the number of rows, size.ws

问题 Is it possible for the terminal to detect ⇧ Shift + Enter↵ or Ctrl + Enter↵ keypresses? I am trying to configure vim to do key mappings that use these sequences, and while they work fine in gvim, they don't seem to work in any terminal console. The curious thing is that although Ctrl + Enter↵ is not detected in vim, mapping Enter↵ to Esc maps properly, but then pressing Ctrl + Enter↵ behaves like Enter↵ ! 回答1: Some terminals send <NL> when <C-Enter> is pressed. This is equivalent to sending

问题 I am trying to import pyodbc module on a windows computer. It works in the terminal, but not the IDLE. The error message in IDLE is: Traceback (most recent call last): File "FilePath/Filename.py", line 3, in <module> import pyodbc ImportError: No module named pyodbc 回答1: This typically occurs when multiple versions of python are installed with different paths.
