child_process.fork(): spawns a new Node.js process and invokes a specified module with an IPC communication channel established that allows sending messages between parent and child. child_process.execSync(): a synchronous version ofchild_process.exec()thatwillblock the Node.js event loop. child...
Version: 6.11.2 Platform: Windows 10 v1703 x64 Subsystem: child_process I'm trying to use exec to interface with the netsh wlan commands on Windows, and I've been having no trouble up until for some reason I get an exit code of 1 for a v...
The synchronous version of child_process.spawn. child_process.spawnSync returns Object. Object contains: pid (child process pid), stdout (standard output), stderr (standard error) and so on. The difference is that the function does not return until the child process is completely closed. const...
The errors with objdump are cases where the cwe_checker internally runs objdump on the file to be analyzed but fails to parse the output (usually because objdump returns an actual error). These are cases that currently cannot be analyzed with the cwe_checker. In general timeout errors are ex...
The error.code property will be the exit code of the process. By convention, any exit code other than 0 indicates an error. error.signal will be the signal that terminated the process. The stdout and stderr arguments passed to the callback will contain the stdout and stderr output of ...

注意:不像 POSIX 系统调用中的 exec(3),child_process.exec() 不会替换现有的进程,且使用一个 shell 来执行命令。 If this method is invoked as its util.promisify()ed version, it returns a Promise for an object with stdout and stderr properties. In case of an error, a rejected promise is ...
error {Error} stdout {string|Buffer} stderr {string|Buffer} Returns: {ChildProcess} Spawns a shell then executes the command within that shell, buffering any generated output. The command string passed to the exec function is processed directly by the shell and special characters (vary based on...
If no child process has that process ID, wait returns immediately. If you specify neither a pid nor a job-id, wait waits for the process IDs known to the invoking shell to complete. In the tcsh shell, the shell waits for all background jobs. If the shell is interactive, an interrupt...
