ms-wmic

node-ms-wmic

A Node.js wrapper for Microsoft Windows' WMIC

Installation

npm i ms-wmic

API

Note: All API methods return the wmic object for chaining.

wmic.execute(args, cb)

Execute WMIC with the provided args

  • string args - WMIC CLI arguments
  • function(null | object err, string stdOut) cb - A function to be called after WMIC is executed

Example

wmic.execute('process where name="notepad.exe" get executablepath', function (err, stdOut) {
    if (err) {
        console.error(err);
    }
    
    console.log(stdOut);
});

wmic.process.get(opt, cb)

Retrieve specific process properties given one or more optional search conditions

  • object opt - An options object
    • object{string | number} | object{object{string | number}} where - (Optional) An object in which a key is
      1. operator, with a value of "AND" or "OR" (case-insensitive). Will determine how search conditions are joined. If omitted, conditions are joined with "AND".
      2. A process property, with a value of either a process property value to match with an equal to comparison or an object containing operator and value keys. operator is a WQL operator or LIKE Operator. value is a process property value.
    • array{string} get - Process properties to get
  • function(null | object err, array{object{string}} processes) cb - A callback to executed after the process properties are retrieved.

Examples

// Get a specific property of all processes
wmic.process.get({get: ['processId']}, function(err, processes, stdOut) {
    if (err) {
        console.error(err);
    }
 
    console.log(processes);
    console.log(stdOut);
});
 
// Simple equal to where comparison
wmic.process.get({
    where: {name: 'spotify.exe'},
    get: ['name', 'executablePath', 'threadCount']
}, function(err, processes, stdOut) {
    if (err) {
        console.error(err);
    }
    
    console.log(processes);
    console.log(stdOut);
});
 
// Advanced comparison via operators
wmic.process.get({
    where: {
        operator: 'OR',
        writeOperationCount: {
            operator: '>',
            value: 10
        },
        executablePath: {
            operator: 'LIKE',
            value: '%C:\\\\Program Files (x86)%chrome.exe%'
        }
    },
    get: ['workingSetSize', 'processId']
}, function(err, processes, stdOut) {
    if (err) {
        console.error(err);
    }
    
    console.log(processes);
    console.log(stdOut);
});

wmic.process.list(where, cb)

Retrieve all available process properties given one or more optional search conditions

  • object{string | number} | object{object{string | number}} where - (Optional) An object in which a key is
    1. operator, with a value of "AND" or "OR" (case-insensitive). Will determine how search conditions are joined. If omitted, conditions are joined with "AND".
    2. A process property, with a value of either a process property value to match with an equal to comparison or an object containing operator and value keys. operator is a WQL operator or LIKE Operator. value is a process property value.
  • function(null | object err, array{object{string}} processes) cb - A callback to executed after the process properties are retrieved.

wmic.process.call(opt, cb)

  • object opt - An options object
    • object{string | number} | object{object{string | number}} where - An object in which a key is
      1. operator, with a value of "AND" or "OR" (case-insensitive). Will determine how search conditions are joined. If omitted, conditions are joined with "AND".
      2. A process property, with a value of either a process property value to match with an equal to comparison or an object containing operator and value keys. operator is a WQL operator or LIKE Operator. value is a process property value.
