How to change the output file name with -w

[petr515]

Hi, i have this command: exiftool -a -u -g1 -w .txt

How can I change the output file name from: <filename>.txt to something like "output.txt" ?

Two ways:

exifool -a -u -g1 -w %0foutput.txt

or

exiftool -a -u -g1 -W+ output.txt

(but the first way is more efficient)

Edit: Wait.  Are you specifying multiple input files?  If so, then you need to use the second command.
