"oShell.Exec(cmd)" - Running System Command with a Script
This section provides a tutorial example on how to run a system command with a VBScript code. Command output and status can be monitored with WshScriptExec properties.
As mentioned in the previous section, WSH offers offers runtime objects to perform system administration task.
Here is a tutorial example that uses WshShell object to run a system command and obtaining its output:
' StdIn_StdOut.vbs '- Copyright (c) 2015, HerongYang.com, All Rights Reserved. Dim oShell, oExec, sLine Set oShell = CreateObject("WScript.Shell") Set oExec = oShell.Exec("ping localhost") ' Reading the output of the shell command thread Do While Not oExec.StdOut.AtEndOfStream sLine = oExec.StdOut.ReadLine WScript.StdOut.WriteLine "Output: " & sLine WScript.Sleep 10 Loop ' Waiting for the shell command thread to end ' In case the output ends before the command Do While oExec.Status = 0 WScript.Sleep 100 Loop
When I ran it on my machine, I got:
C:\herong>cscript Shell_Exec.vbs Output: Output: Pinging localhost [127.0.0.1] with 32 bytes of data: Output: Output: Reply from 127.0.0.1: bytes=32 time<1ms TTL=128 Output: Reply from 127.0.0.1: bytes=32 time<1ms TTL=128 Output: Reply from 127.0.0.1: bytes=32 time<1ms TTL=128 Output: Reply from 127.0.0.1: bytes=32 time<1ms TTL=128 Output: Output: Ping statistics for 127.0.0.1: Output: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Output: Approximate round trip times in milli-seconds: Output: Minimum = 0ms, Maximum = 0ms, Average = 0ms
