Thanks for this tip! i've modified it slightly and wrapped it in a shell
script:
--- cut here /usr/local/bin/jpegsize---
#! /bin/sh
for i in "$@" ; do
echo -n "$i: "
(cat $i | djpeg -v -targa>/dev/null ) 2>&1 | \
sed -n -e 's/Start Of Frame.*://' -e 's/, components=.*//p'
done
--- cut here /usr/local/bin/jpegsize---
$ jpegsize ~cas/public_html/*.jpg
