MS-Task

Description

MS-Task is a Node.js wrapper for Microsoft Windows' tasklist and taskkill. Tasklist "displays a list of applications and services with their Process ID (PID) for all tasks running on either a local or a remote computer." Taskkill "ends one or more tasks or processes." Supported versions: Windows XP, Vista, 7, and 8.

Installation

You may install MS-Task via NPM as follows:

npm install ms-task 

The source code is available on GitHub.

Commands

task( argumentString, callback( err, processString ))

Call tasklist.exe with the supplied argumentString. A valid argumentString is documented here and in the test. Be sure to use nested or escaped quotes when necessary in the argumentString. The callback contains err and processString variables. err is null if no erros were encountered when calling tasklist.exe with the supplied argumentString. processString is a table, list, or CSV string of information about a matched process or processes, depending on the supplied argumentString. Choosing CSV and using node-csv is an easy way to deal with the resulting data.

task.list( argumentString, callback( err, processString ))

This convenience method is equivalent to task().

task.procStat( pidOrProcessName, callback( err, processes ))

Search for a given pidOrProcessName. Both string and numeric PIDs are supported. err is null if one or more processes were found. processes is an object which contains information (process name, PID, session name, session number, and memory usage) about a matched process or processes. It has two properties, array (an array of arrays) and object (an array of objects). The properties of processes.object are name, pid, sessionName, sessionNumber, and memUsage. For example, to find the memory usage of the first process found, you could use processes.array[0][4] or processes.object[0].memUsage.

task.pidOf( processName, callback( err, processes ))

Search for one or more PIDs that match a given processName. err is null if one or more PIDs were found. processes is an array of matched PIDs.

task.nameOf( pid, callback( err, processName ))

Search for the processName that corresponds with the supplied integer or string pid.Err is null if a process name was found.

task.kill( proc, callback( err))

Kill a given process name or PID (proc). The callback is optional, and err is null if no erros were encountered when calling taskkill.exe with the supplied proc. If a process name is passed for proc, and multiple matches are found, all of the matches are killed.
