Assuming you have them in a directory called photos, while in that
directory
First test it.
for i in *.jpg;do echo mv "$i" "${i%%.jpg}" A.jpg;done
This will show you what it would do. For example,in a directory that has
two pictures, 1.jpg and 2.jpg I ran the command and get
for i in *.jpg; do echo mv "$i" "${i%%.jpg}"A.jpg;done
mv 1.jpg 1A.jpg
mv 2.jpg 2A.jpg
Once you've tested it by using echo you can now it for real.
for i in *.jpg;do mv "$i" "${i%%.jpg}" A.jpg;done
In this case, what we're doing is what's called a for loop, (because it
uses the word for, as opposed to a while loop). for i in *.jpg means for a
a variable, which we're callling i, in a group, in this case, any file
ending with .jpg, move, (in this case, that means rename) the file. The
${i%% means that we're going to get rid of whatever comes after the %%, in
this case, .jpg, then outside of the bracket, put in a letter A and put the
.jpg back. There are other ways and scripts, but that is one of the
simpler methods, IMHO.
