Guest rpremuz@yahoo.com Posted August 2, 2007 Posted August 2, 2007 Hello, I have a question for a MS MVP. What is the maximum length of a command that you can put in a Windows scheduled task (its run field)? E.g. http://support.microsoft.com/kb/830473/en-us gives command-line string limitations for various versions of MS Windows but does not tell anything about the Windows Scheduler. -- rpr. /Robert Premuz/
Guest Gary S. Terhune Posted August 2, 2007 Posted August 2, 2007 Re: maximum command length in Windows Scheduler Can't say with absolute certainty, but as that article has the same figures for all the examples -- "...either 2047 or 8191 characters (as appropriate to your operating system)" -- I would assume those figures also apply to a command for Scheduled Tasks. Only other figure I could imagine would be 255 or 256 characters, but I just created a scheduled task with a command 270 characters long and it ran just fine. -- Gary S.

It would be totally unmanageable! If you really want to find out then you can do so quite easily, by scheduling this command to run: cmd /c echo 1234567890x Now double the numerical string time and again and check how long it takes until the trailing "x" disappears. The test may be tedious (and IMHO futile) but it will give you an authoritative answer.
Guest Chuck Posted August 3, 2007 Posted August 3, 2007 Re: maximum command length in Windows Scheduler Somewhere in the past, along with the long file and folder names, the buffer for command lines got larger. Long folder names several layers deep plus a long file name or two can easily fill a very large command line buffer.
