I need to homogenize a set of files where the minimum value is always 1 while the maximum should be 366

I would like to use GDAL to perform this operation and this is my code:

for tiff in `cat list.txt`; do
        fname=${tiff##*/}        
        /usr/bin/gdal_edit.py -a_nodata 0 $tiff       
        /usr/bin/gdal_translate -of GTiff -scale 1 366  $tiff $output_folder$fname

but the output image is not correct and its size is bigger than the input one

What am I doing wrong?
