问题 In GNU/Linux I would do: PROGPATH=/long/and/complicated/path/to/some/bin $PROGPATH/program args... but in Powershell if I try this: $PROGPATH=\long\and\complicated\path\to\some\bin $PROGPATH\program args... I get: At script.ps1:2 char:... + $PROGPATH\program args ... + ~~~~~~~~ Unexpected token '\program' in expression or statement. + CategoryInfo : ParserError: (:) [], ParseException + FullyQualifiedErrorId : UnexpectedToken So how do I do this simple thing I know how to do in bash, in

Closed 5 years ago . I have an enum for 25 applications and an enum for some environments. Right now with the code I have I can either pass no arguments and it runs all of the application in all of the environments(which is what I want) or I can pass one app and one environment in that order it will run that. I need to

问题 I am using a bash script to call and execute a .jar file from any location without having to constantly enter its explicit path. The .jar requires additional variable parameters to be specified at execution, and as these can be anything, they cannot be hard coded into the script. There are 3 variables in total, the first specifies 1 of 2 actions that the .jar is to make, the second specifies a target file to enact this action on and the third specifies the name of a file that the action is to

问题 I am trying to get commandline arguments of an executable which was launched by another program. I tried the command mentioned in this answer, but I can't understand the syntax :( I am trying to get the commandline arguments of an process, I have the PID & the process name, In this case I am trying get arguments of an ping command which I am using to test the command... Thanks in Advance :) 回答1: Try this: wmic process where "name='ping.exe'" get commandline /format:list Or if you prefer to

问题 Note: A summary of this question has since been posted at the PowerShell GitHub repository, since superseded by this more comprehensive issue. Arguments passed to a command in PowerShell are parsed in argument mode (as opposed to expression mode - see Get-Help about_Parsing). Conveniently, (double-)quoting arguments that do not contain whitespace or metacharacters is usually optional , even when these arguments involve variable references (e.g. $HOME\sub ) or subexpressions (e.g., version=$(

问题 I am just starting out with Groovy. I couldn't find any examples anywhere of how to handle arguments to a Groovy script and so I hacked this method myself. There must be a better way of doing this? If so, I am looking for this better way, since I am probably overlooking the obvious. import groovy.lang.Binding; Binding binding = new Binding(); int x = 1 for (a in this.args) { println("arg$x: " + a) binding.setProperty("arg$x", a); x=x+1 } println binding.getProperty("arg1") println binding

问题 I was just writing a console utility and decided to use NDesk.Options for command-line parsing. My question is, How do I enforce required command-line options? I see in the docs that: options with a required value (append '=' to the option name) or an optional value (append ':' to the option name). However, when I put a = at the end of the option name there is no difference in behavior. Ideally the Parse method would throw an exception. Is there something else I need to do? Here is my test

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 new to Rust, trying to learn safe programming by working with the borrow checker. One thing I tried was to construct a std::process::Command based on input. If I just wanted to do what all the examples in the documentation assume I want to do and just run a command with arguments that I know at coding time, it works fine: use std::process::Command; fn main() { let mut command = Command::new("/usr/bin/x-terminal-emulator") .arg("-e") .arg("editor") .output() .unwrap(); } I'm trying to run
