I do most of my basic image file manipulations via command line as well.
Items such as rotating photos according to EXIF information, to renaming the
file name more accordingly. Simply and basic tasks should not be made more
difficult by using graphical interfaces. These basic tasks can be completed
far more exponentially faster and among many more files than using a graphical
interface.
I use the following within a Bash script function for processing my photos
downloaded from my USB connected camera using GPhoto.
# Change upper to lower case filenames using mv & tr.
printf "Convert upper to lower case file names...\n"
for photo in ${TMPDIR}/*; do
mv $photo `echo $photo | tr [:upper:] [:lower:]` >>$LOGFILE 2>&1
done
# autorotate images according to the exif-flags
# also set modification time to exif-date/time
# exit codes of jhead: 0=OK, 1=Modified
#jhead -autorot -ft *.JPG >> $ERRORLOG
# 0x0112 Orientation left - bottom -> needs 270 deg rotation
# "top - left" -> is up right, no rotation needed.
## jhead -cmd 'jpegtran -rotate 270 -outfile &o &i' *.JPG
# auto rotate images in place according to orientation exif data.
# requires: media-libs/jpeg /usr/bin/exifautotran
printf " auto rotating images\n"
exifautotran $TMPDIR/*.jpg >>$LOGFILE 2>&1
# Set time stamp according to time exif data
# requires: media-gfx/jhead /usr/bin/jhead
printf " setting file time to image exif time\n"
jhead -ft ${TMPDIR}/*.jpg >>$LOGFILE 2>&1
# jhead returns "1" in case of unsuccessful modification (e.g. rotation)
if [ "$?" -lt "0" ]; then
error "Error in jhead setting timestamp on file, code: $?"
fi
