 If you're using a bash shell, you might try a script along these lines:

====================
outputdir=/home/newdata
inputdir=/home/data

cd $inputdir
for raster in *; do

  gdalinfo $raster

  # If gdalinfo returned exit code 0,
  # we can assume its a valid raster image
  if [ $? = 0 ]; then

    # Assume the file prefix is everything before the first '.'
    prefix=` echo $raster | sed 's/\..*//'`

    # use gdal_translate to convert to ERDAS Imagine format
    gdal_translate -of "HFA" $raster ${outputdir}/${prefix}.img

  fi
done
=====================
