terminal

问题 We're reading a file from stdin into file_buffer , and then stepping into a method more . As soon as we use system("stty cbreak -echo"); , the output prints "stty: stdin isn't a terminal" and doesn't set our terminal to the settings we asked for. This problem only exists when we use standard in. If we use a file argument, the program works fine -- the terminal settings get set, and there is no error message. So, this is okay: myprogram file1.txt But this is not: myprogram < file1.txt Either

问题 I need a sh script to do remove the first 3 characters of file names, for example: "AB file 1.pdf" "BC file 2.pdf" "DB file 3.pdf" "AD file 4.pdf" ... to: "file 1.pdf" "file 2.pdf" "file 3.pdf" "file 4.pdf" ... I think the script will be like: #!/bin/sh for i in *.pdf; do newName= ???? mv $i $newName done 回答1: Use the cut command: newName=$(echo "$i" | cut -c4-) In bash you can use a Parameter Expansion extension: newName=${i:3} Also, don't forget to quote your variables: mv "$i" "$newName"

问题 I'm writing a program in C# on my computer which should start a Python program on a remote Raspberry Pi. For the moment the Python code is just printing 'Hello' every second. The program should run permanently. When I start this program from C#, I would like to have a visual feedback, if my program is running – I'd like to see the printed output like in PuTTY. The following code works fine for a command like ls . But for the reason that my Python program test.py should not finish – I never

问题 I'm trying to get the prompt reset, forget all the variables and start the prompt from line 1> I'm aware of the following built-in functions f(). %% forget all io:format("\e[H\e[J"). %% "clear screen" and moving cursor to the begin of the line but when I'm writing the following commands, it does forget all the variables, but it doesn't "reset" the screen, just clear the screen, like clear command in the terminal. in Linux, I just type reset , but I couldn't find equivalent command or built in

问题 I am creating a Linux terminal program using C. I am trying to make a two digit code address a array location. I don't want to have to hit enter after every two digit input, I want the input to just be sent to my buffer variable through scanf directly after to characters are entered. I do not have a code sample, as i have no idea how to approach this. Thanks for any help! 回答1: You've got two options, which solve the same problem in nearly the same way. The first is to use stdbuf when you run

问题 I've been trying to build a Terminal Emulator for Android. Being pretty new to this, my idea was to execute each command and store the output in a file, whose contents would be displayed after each execution. Pseudo Code : public Boolean execCommands(String command) { try { rt = Runtime.getRuntime(); process = rt.exec("su"); DataOutputStream os = new DataOutputStream(process.getOutputStream()); os.writeBytes("echo $ \""+command+ "\" >> /sdcard/Android/data/terminalemulatorlog.txt\n\n\n"); /**
