child-process

问题 I want to be able to take a command string, for example: some/script --option="Quoted Option" -d --another-option 'Quoted Argument' And parse it into something that I can send to child_process.spawn : spawn("some/script", ["--option=\"Quoted Option\"", "-d", "--another-option", "Quoted Argument"]) All of the parsing libraries I've found (e.g. minimist, etc.) do too much here by parsing it into some kind of options object, etc. I basically want the equivalent of whatever Node does to create

问题 I have code to spawn child process like this: const spawn = require('child_process').spawn; const ls = spawn('ls', ['-lh', '/usr'], { detached: true }); ls.stdout.on('data', (data) => { console.log(`stdout: ${data}`); }); ls.stderr.on('data', (data) => { console.log(`stderr: ${data}`); }); ls..on('error', (data) => { console.log(`error: ${data}`); }); ls.on('close', (code) => { console.log(`child process exited with code ${code}`); }); Till now, I can console message from stdout and stderr,

问题 I am attempting to launch nvm within a child process in Nodejs on OSX However in doing so, I am getting the following error: /bin/sh: /Users/miker/.nvm/nvm.sh: Permission denied. child process exited with code 126 (I call the explicit path to nvm, since running without it, the child process can't see the executable.) This is obvious that it is a permission issue. However, I am not sure why since I can launch the commands on there own without issue. It is only when launching in a child process

问题 I'm trying to implement a timeout -like command on a unix -based operating system as follows: int pid; timer_t timer_id; struct sigevent timer_event; struct itimerspec timer_value; void timeout_signal_handler(int sig_no) { kill(pid, SIGKILL); } int create_timer() { /* implementation */ } int start_timer_oneshot(int interval_ms) { /* implementation */ } int main(int argc, char* argv[]) { int status, pid_return; void *signal_return; if (argc < 2) return EXIT_FAILURE; signal_return = signal

问题 I am trying to do some work on a remote server using ssh--and ssh is called on the local machine from node.js A stripped down version of the script looks like this: var execSync = require("child_process").execSync; var command = 'ssh -qt user@remote.machine -- "sudo mv ./this.thing /to/here/;"'; execSync(command,callback); function callback(error,stdout,stderr) { if (error) { console.log(stderr); throw new Error(error,error.stack); } console.log(stdout); } I get the requiretty error sudo:

问题 I am using nodejs to communicate with a casperjs script i have made. first of all i will tell you what my Casperjs script does. i have set it up with command line input. i the run this command casperjs script.js "Inputdata1" "inputdata2" this script then executes and visits one of my servers submits the input data 1 & 2. then waits for a server response and rights a line to one of 10 text files depending on the result the script gets from my server this then exit. this casperjs script works

问题 Scroll down to see new update Update:: In other word: I want to launch another program in the manner of a shell on Windows. Need a two way communication between parent and child process using c++ on Windows. The parent is my program and the child is a random console application (like mysql terminal). It's been a couple days searching but couldn't find any working solution for Windows. Also MS documentations is not helping. Here i got a sample code from a question asked three years ago. How
