问题 I have been reading about ptys from this page's example: http://rachid.koucha.free.fr/tech_corner/pty_pdip.html. I have two questions: What is the difference, or the most important difference, between using a pty and using a pipe? From what I have read, both are for inter-process communication, but with a pty the process can "treat it like a normal terminal". What does that mean? What is a "controlling terminal"? I have read about them but can't understand what they really are. Is the

问题 I'm trying to change the default path of the integrated terminal in Visual Studio Code, but I'm not sure how to.

The current default path is C:\Users\User_Name . I'd like to change it to C:\Project . How do I do this in Visual Studio Code? 回答1: Short answer Edit the user preference "terminal.integrated.cwd": "" to the path that you want

问题 Every time I try to do npm install I am getting the following error. How do I fix this? I am on node -v → v8.8.0 & npm -v → v6.11.3 I tried running it on vsCode terminal and iTerm , I ended up getting the same error. (both are updated to the latest version).

问题 Mac OSX Lion 10.7. In an effort to get around weird environment stuff (homebrew wasn't installing wget, and I had all sorts of weird blocks and errors), I uninstalled zschrc and homebrew and a bunch of other stuff, then installed fish shell. Now, whenever I try to push/pull to/from github, I get this error: The authenticity of host 'github.com (204.232.175.90)' can't be established. RSA key fingerprint is <string of colon-separated chars that I should probs keep private>. Are you sure you

问题 Running this script bash ./cleanup.bash #!/bin/bash ## going to dir moving stuff rm -rf !(composer.json|.git) Gives the error: cleanup.bash: line 10: syntax error near unexpected token '(' cleanup.bash: line 10: 'rm -rf !(composer.json|.git)' But if I run in in the terminal directly no problem rm -rf !(composer.json|.git) I tried stripping out all other lines, still get the error. How do I enter this correctly in the bash script? 回答1: I guess your problem is due the shell extended glob option

问题 I am trying to build a simple CLI interface for my go process, I need to listen and serve on TCP port and get stats when connected to the port on TCP . I came across 'terminal' package to help with Password prompt, command history and other things. I tried to write up some code to achieve this. Although my client is not receiving any prompt or server is stuck on 'ReadLine' method. Any helpers? package main import ( "bufio" "fmt" "golang.org/x/crypto/ssh/terminal" "io" "net" _ "time" ) func

问题 My current script does the following; It takes integer as a command line argument and starts from 1 to N , it checks whether the numbers are divisible by 3, 5 or both of them. It simply prints out Uc for 3, Bes for 5 and UcBes for 3,5. If the command line argument is empty, it does the same operation but the loop goes to 1 to 20. I am having this error "Too many arguments at line 11,15 and 19". Here is the code: #!/bin/bash if [ ! -z $1 ]; then for i in `seq 1 $1` do if [ [$i % 3] -eq 0 ];
