command-line-arguments

问题 I am running Python 3.4.3 on Linux 3.16.0. I want to use subprocess.Popen to run a command with a long single argument (a complex Bash invocation), roughly 200KiB. According to getconf and xargs , this should be well within my limits: $ getconf ARG_MAX 2097152 $ xargs --show-limits < /dev/null Your environment variables take up 3364 bytes POSIX upper limit on argument length (this system): 2091740 POSIX smallest allowable upper limit on argument length (all systems): 4096 Maximum length of

问题 How can I pass command line arguments to a standalone MATLAB executable running on Linux/UNIX? I need to compile my MATLAB script as a standalone file that can be run on a machine without MATLAB present. It needs to be able to work in a way similar to C's argv[] , where you do the following: Command line: myfile argument1.txt argument2.txt where argument 1 and 2 are the input and output files. The exact syntax doesn't matter, but it should work like argv[] . What is a function that could do

问题 I need to run a PHP script from command line and I need to set some environmental variables. Unfortunately, following does not work: php -dAPPLICATION_ENV=staging script.php What I'd like to accomplish is having APPLICATION_ENV variable set. 回答1: APPLICATION_ENV=staging php script.php The variable will be available in the $_SERVER array: echo $_SERVER['APPLICATION_ENV']; 回答2: There is no way to set environment variables from the command line specifically for the execution of a script by

问题 I would like to know how to call more than 9 argument within a batch script when calling a label. For example, the following shows that I have 12 arguments assigned along with attempting to echo all of them. CALL:LABEL "one" "two" "three" "four" "five" "six" "seven" "eight" "nine" "ten" "eleven" "twelve" PAUSE GOTO:EOF :LABEL echo %1 echo %2 echo %3 echo %4 echo %5 echo %6 echo %7 echo %8 echo %9 echo %10 echo %11 echo %12 The output for %10 %11 and %12 ends up being one0 one1 one2. I've

问题 I've searched all over and tried different variations of commands, but I am still not there yet. My goal is to run an exe that already resides on a remote machine and pass in command line arguments. I've tried invoke-command, but I can't seem to get my syntax to recognize the arguments. Methods tried: Win32_Process.Create() Invoke-Command Start-Process [diagnostics.process]::start Invoke-WmiMethod From my tests, the closest I can get is with the following command: $command = "program.exe -r

问题 I'm getting the standard WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is error message. However, the system (Appworx) that executes the command (sftp I think, not that it matters) is automated and I can't easily accept the new key, even after

问题 I'm looking for a way that I can parse command line arguments into my WPF application with just a way of reading the value of the argument that the user passed. As an example application.exe /setTime 5 is there a way for me to have some code where I can just say: MessageBox.Show(arg("setTime")); Which will output 5 Working Solution How to create smart WPF Command Line Arguments 回答1: The way I always do it is to specify the arguments as a "name"/"value" pair e.g. myprogram.exe -arg1 value1

问题 I need to get an argument and convert it to an int. Here is my code so far: #include <iostream> using namespace std; int main(int argc,int argvx[]) { int i=1; int answer = 23; int temp; // decode arguments if(argc < 2) { printf("You must provide at least one argument\n"); exit(0); } // Convert it to an int here } 回答1: Since this answer was somehow accepted and thus will appear at the top, although it's not the best, I've improved it based on the other answers and the comments. The C way;

问题 I would like to make my python script run from the command line when supplies with some arguments. However, one of the arguments should be a list of options specific to one segment of the script. Would string parsing be the only way to do this by actually constructing the list after the "command line list" string is split from commas? If so, how would you go about that? Example: -details=['name', 'title', 'address'] 回答1: Program: import sys, ast, getopt, types def main(argv): arg_dict={}

问题 I'm wondering if it's possible to populate sys.argv (or some other structure) with command line arguments in a jupyter/ipython notebook, similar to how it's done through a python script. For instance, if I were to run a python script as follows: python test.py False Then sys.argv would contain the argument False . But if I run a jupyter notebook in a similar manner: jupyter notebook test.ipynb False Then the command line argument gets lost. Is there any way to access this argument from within
