Hi,
This script takes all pictures in a folder and adds an invisible watermark using steganography.
I would like to modify it so that i can use a wordlist for watermarking (lets say 100 ID's/names) and then creating a picture with each ID where basename is 01.file.jpeg.

Example
01.copyrighted.jpeg (watermark: John)
02.copyrighted.jpeg (watermark: Jenny)
And so on.

I'm new to bash scripting, so if anyone could modify this script to meet the requirements i would be really greatful!

echo -n "insert watermark: "
read var_watermark
echo $var_watermark > watermark
echo -n "Enter Password: "
stty -echo
read watermarkpassword
stty echo
echo " "
ls -1 *.[jJ][pP][gG] | while read file;
do {
steghide embed -p $watermarkpassword -cf "$file" -ef "watermark" -sf "`basename TAGGED_"$file"`"
}
done
rm -f watermark
echo "Done"

You should enclose your code into "code" tags: either use square brackets, or click on Code.

Also, instead of parsing output of ls, it's better to use

To change the script to read the names from a file is easy:

The solution is correct ... with the little exception that the 'file' variable is not assigned a value
I would suggest this little correction to the solution :

sorry, read 'nocaseglob' instead of 'nocasematch' in the script above
here is the script again, with correction :


echo "Done"

another correction to the solution : to support spaces in file names
