Add date+time to filename

Is there a way to add the date+time to a filename when redirecting output? This is to be done in a Shell directly or a script.

MyProgram >T:Output_[date+time].txt

So each run doesn't overwrite the previous output file.

What I usually do is set up a Shell variable with the date part of the filename, using something like "set dt = `date {your format codes here]`" (note the backticks).

Then you can use $dt as part of your filename - or, if you refer to it lots of times, set up another variable like "set fn = T:Output_$dt.txt" and then just use $fn when you need the filename.

Note: Untested, away from my Amigas right now.

Best regards,

Maybe some variation of this:

echo testing >ram:testfile`date LFORMAT %H%M%S`

Note that the hash marks enclosing the date command are not single quotes; they are the character below the Esc key on a standard keyboard (I.E. the key with ~ and `).

@mritter0

if it's not strictly the date you are after but the overwriting of the previous file from a script, maybe adding the process number to the file name is an option?

Sweet. Worked great. Thanks

In case you need a single file containing the cumulative output data of previous execution/run , you may use: MyProgram >>T:Output.txt
