Anyways, I use this vbscript to check the age (in minutes) of the newest file in a folder. In my case a process I monitor is supposed to export a daily file so I use:
testname "c:\myfolder" 1440
The only weird thing is that the optional file filter has to be in regular expression format like:
testname "c:\myfolder" 1440 ".txt$" (for files matching *.txt)
NewestFile.vbs:
Code: Select all
Option Explicit
Call main
Sub main
On Error Resume Next
Dim FSO, fsFolder, objArgs, item, NewestFile, regEx, strPath
Dim intAgeMinsMax, intAgeMins, strPattern
Set objArgs = WScript.Arguments
If (objArgs.count<2) Or (objArgs.count>3) Then
wscript.stdout.write "scriptres:BAD:Invalid number of parameters 2 or 3 (you supplied "& objArgs.count & ") (e.g. c:\temp 30 .txt$)" & vbCrLf
wscript.stdout.write " ---------------------------------------------------"& vbCrLf

wscript.quit
