First of all, make sure forfile command returns the files you want to process.
The next command prints all HDF files' name in the folder:
forfiles /p C:\Users\HP\Desktop\deneme\ham_veri /m *.hdf /c "cmd /c echo @path
You may think of using this:
FORFILES /m *.hdf /P C:\Users\HP\Desktop\deneme\ham_veri /C "cmd /C gdal_translate -sds @file C:\Users\...

This seems to work, just using gdal_calc.py:
gdal_calc.py -A a1.tif --outfile=a3.tif --calc="(A<-9000)*65535 + (A>0)*A+8500" --NoDataValue=65535 --type=Int32 --overwrite
converts to Int32
shifts the valid data up by 8500
shifts and sets the nodata value to 0xFFFF
You might need to change the nodata test as my nodata value was -9999 but I ...

The functional solution is to use sed.
sed -i '/<Entry c1="0" c2="0" c3="0" c4="255" \/>/,/<Entry c1="255" c2="255" c3="255" c4="255" \/>/d; /<ColorTable>/r COLORTABLE.txt' $F_VRT
Or COLORTABLE.txt contains the values I want.

The Python package osgeo.gdal is not really "Pythonic", so there are several quirks and gotchas to be aware of.
The NoneType returned from Open means that the file could not be opened. Here's a quick demo:
from osgeo import gdal
ds = gdal.Open("NETCDF:file.nc:velocity")
# you may see the following message in a console:
# ERROR 4: `NETCDF:...

Try this:
gdal_translate -a_ullr -180 90 180 -90 NETCDF:test.nc:chlor_a_diff test.tif
Original file:
print(gdal.Open('test.nc').GetGeoTransform())
=> (0.0, 1.0, 0.0, 0.0, 0.0, 1.0)
gdal_translate -a_ullr -180 90 180 -90 NETCDF:test.nc:chlor_a_diff test.tif
print(gdal.Open('test.tif').GetGeoTransform())
=> (-180.0, 0.020830922346950585, 0.0, 90.0, 0.0,...
