问题 Here's what I need to do: I need to copy files over the network. The files to be copied is in the one machine and I need to send it to the remote machines. It should be automated and it should be made using python. I am quite familiar with os.popen and subprocess.Popen of python. I could use this to copy the files, BUT, the problem is once I have run the one-liner command (like the one shown below) scp xxx@localhost:file1.txt yyy@]192.168.104.XXX:file2.txt it will definitely ask for something

问题 I wrote this script to compare 2 numbers in bash but it gives me wrong answers for some numbers. like if I give it 2&2 for input , it gives me "X is greater than Y" #!/bin/bash read num1 read num2 if [ $num1 > $num2 ] then echo "X is greater than Y" elif [ $num1 < $num2 ] then echo "X is less than Y" elif [ $num1 = $num2 ] then echo "X is equal to Y" fi 回答1: You can try with bash arithmetic contexts: #!/bin/bash read num1 read num2 if (( num1 > num2 )) then echo "X is greater than Y" elif ((

问题 I'm working on MacOS and want an SSH/Git login with a seccond ssh-key. I have two key pairs in ~/.ssh/ id_rsa id_rsa.pub id_rsa.gitlab id_rsa.gitlab.pub id_rsa and id_rsa.pub are the older key. This key is working fine. But where the second key is needed, i can't login. It trys the first key and fails. Running this command ssh-add /Users/kevin/.ssh/id_rsa.gitlab helps. But after a reboot, it dosen't work anymore and i must run the command again. Is there a better solution as run this command

问题 I'm writing a c program on Linux that writes text into a file. I'm having trouble where i'M trying to use system("gcc fileName.c") to compile the new document i created into an executable. The file is getting the following input: char Msg[100] = {"#include <stdio.h>\nint main();\n\nint main()\n{\n\n\treturn 0;\n}"}; clearly it has a main() function and yet it still gives me the following wall of error: /usr/bin/ld: /usr/lib/debug/usr/lib/i386-linux-gnu/crt1.o(.debug_info): relocation 0 has

问题 I have PhpStorm 2016.2 and I added Cygwin in the Shell path as follow : "C:\cygwin64\bin\env.exe" CHERE_INVOKING=1 /bin/bash.exe It's working well, but the colors do not work. For exemple I have ?[32m Name instead of having Name colored in green. I tried several things like adding the plugin Grep Console to have the support of ANSI Color, but didn't work. It's really hard to work with lines with multiple ANSI colors ?[39m ?[32m Scheme ?[39m ?[32m Host ?[39m ?[32m Path . Do not hesitate to ask

问题 How do I change it, so executable files don't have another color, compared to other files? I'm on macOS Sierra (10.12.6). It's the same, both in the regular Terminal: ... or in iTerm2: It's frustating to look at. If i write chmod -x [FILENAME] then it disappears. But I don't want to change if the files are executable or not, - I want to change the color of executable files. I want my files to look like this (regardless of if it's executable or not): 回答1: I tried correcting Anshuman's answer,

问题 I would like to run a local javascript file in chrome console but do not want to copy and paste the code. I know there is a command I can run from terminal to open the file in a new chrome window/tab but cannot recall it nor find example of it on-line. What command can I call from the terminal to open a .js file in a new chrome tab where I can then run it in console? 回答1: I don't think you can do exactly that. To run JS with having access to the console, you can either copy its source to the

问题 As you can see from this excerpt, there is a "!" before the git command. What's the point? [alias] commitx = !git add . && git commit - https://stackoverflow.com/a/8956546/1354543 I understand aliases and what the command itself is doing, but not the point of the "!" before the git command. 回答1: The ! means "run the following as commands to the shell", so in this case the alias git commitx expands to the equivalent of running git add . && git commit (which is a terrible terrible idea) 回答2: An

问题 this might be a simple question, but how do I "request" system / root priviliges from the user in a c console application. I need to write to /Private/etc but i can't. This is for mac / unix. I've seen it being used in other console commands e.g. when you run the following command: "sudo /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder", Terminal asks you for your Password. How do I do this? thanks, JNK 回答1: There isn't any system call which will let a process obtain root
