terminal

问题 I can't seem to get termcap 's "cl" command to work, but the terminal escape code does. For example: #include <termcap.h> #include <stdio.h> int main() { tputs(tgetstr("cl", NULL), 1, putchar); } This doesn't change the terminal. But when I run: #include <stdio.h> int main() { printf("\e[2J"); } or if I call echo `tput cl` The terminal is cleared. Why does this happen? Shouldn't termcap give that same escape code? EDIT: Fixed writing characters EDIT2: It's because i didn't call tgetent()

问题 I just updated Xcode to 11.4 and suddenly my terminal (iTerm 3.3.9) is now very slow. Typing a command works fine, but upon pressing enter I often wait 3-4 seconds to perform a simple task ( cd , git add , etc). When I look at the status bar I notice that xcodebuild is running during the time while I am waiting. I'm assuming that the new Xcode update did something that makes this process longer or needs a setting updated somewhere. I have already tried sudo xcodebuild -license accept and that

问题 Not sure if this is from Big Sur, installing the Docker extension or what else it could be but in the last week, I have noticed that when typing in the VScode terminal, every single time that I've done my git add. , git commit -m "etc", git push origin master, there is always once or twice where the terminal visually shows that I'm not typing anything for a brief moment. It essentially lags and shows the typing white square icon and in 1 second after a brief "pause" what I was actually typing

问题 I am trying to use the 'firebase' command from my Mac terminal to deploy firebase cloud functions using 'firebase deploy --only functions'. I just used this command a week or two ago when I updated my firebase-functions and firebase-tools to version 3.18.4 but now everytime I try to use the 'firebase' keyword to run a command it says -bash: firebase: command not found . When I run npm -g list I see that I have firebase, firebase-tools and more in that list. I've tried running 'npm install -g
