Hello -- does the TOUCH command when used with the /r switch update all 3 timestamps? modify, access, create times?

 

[rconn]

No. TOUCH will only modify a single timestamp per /R invocation.

But you could cheat a bit with:

TOUCH /r:w /r:c /r:a sourcefile targetfile

WOW thanks for the shortcut ... there is a bug in robocopy introduced by kb3125574 that now robocopy is using the access time to
copy the source to the target is the source time is later than the target time -- using touch I should be able to get around this problem -- thanks

Attempting to update all three file dates using a command copied from above:

Only the /r:a is updated/copied
Trying without the /r:a changes a source date/time as well as a target date/time. The source and target date/times are updated with the current system time and the targets date. Totally unexpected.

d:\tcmd v22>touch /r:w /r:c history.sav test1.tmp & filedates.btm history.sav test1.tmp, still without affecting the creation date/time.

The only method to copy the sources creation date/time, that succeeded, was to use "touch /r:c History.sav test.tmp" alone.
The changes to the source date/time baffle me, since I did not expect the source date/time to ever change with using /r:.
I assume this is WAD so I'm back to using the /r:[acw] individually.
BTW, I tried this in V21 with similar results.

No. TOUCH will only modify a single timestamp per /R invocation.

But you could cheat a bit with:

TOUCH /r:w /r:c /r:a sourcefile targetfile

Might be nice if you could give multiple letters after the /R:

TOUCH /r:acw source target

TOUCH /r:w /r:c /r:a sourcefile targetfile

I saw that. It doesn't work.

This works (third command below) but it's a tad cumbersome.

Agreed, but that's what aliases are for; right?
