It works now.
#!/bin/sh
value=`compare -metric AE -fuzz 10% 2.jpg 5.jpg null: 2>&1`
test=`convert xc: -format "%[fx:$value<420000?1:0]" info:`
if [ $test -eq 1 ]; then
convert 4.jpg oldid.jpg
else
convert 4.jpg newid.jpg
fi

Now, i know that because using -subimage-search makes it slower.

Thank ...

What is the error message when running the script?

I suspect the sed command is likely not doing the right thing, because the output from compare is now different.

compare -metric rmse rose: \( -size 70x46 xc:red \) null:
28533 (0.435386)

But

compare -metric NCC rose: \( -size 70x46 xc:red ...

Ther is error mesage is: But there is still a output and the output is awalys newid.jpg which is in the else statement.

After testing out different error measure, i realised that the script take too long to finish is because of "-subimage-search".

So, i took out "-subimage-search", but after tooking it out, there an error that say the width and height of the small and large image is different.

Then, I use the OldID ...

Finally it works!

I updates my imagemagick to the latest version.
The script is:
#!/bin/sh
value=`compare -metric rmse -subimage-search 2.jpg 1.jpg null: 2>&1 | sed -n 's/^.*(\(.*\)).*$/\1/p'`
test=`convert xc: -format "%[fx:$value<0.022?1:0]" info:`
if [ $test -eq 1 ]; then
convert 4.jpg oldid ...

I don't think i can install the lastest version as my ubuntu synaptic latest version is 6.6.9-7

The latest is 6.7.8.10 should i install that?

It get me to the man pages for sed.

I think it really is my version of imagemagick. So, i will now update to version 6.7.8

Should i upgrade my imgaemgaick to version 6.7.8?

value=`compare -metric rmse -subimage-search rose: xc:red null: 2>&1 | sed -n 's/^.*(\(.*\)).*$/\1/p'`
echo "$value"

It does not return anything.

The version im using is:
Version: ImageMagick 6.6.9-7 2012-04-30 Q16 http://www.imagemagick.org

The command works and this is the result:

This is the output:

Ok, i think there a problem with the first simple command.

When i tried out this:
compare -subimage-search -metric rmse newID.jpg student.jpg result.jpg
I was using windows and it works.

But when i tried it out on my Ubuntu, the command line is also stuck.

Unfortunately, after changing it, it still cannot work.
#!/bin/sh
threshold=0.022
value=`compare -metric rmse -subimage-search 2.jpg 1.jpg null: 2>&1 | sed -n 's/^.*(\(.*\)).*$/\1/p'`
test=`convert xc: -format "%[fx:$value<threshold?1:0]" info:`
if [ $test -eq 1 ]; then
convert 4.jpg oldid.jpg
else ...

It still cannot work.
I did what you say and change it to:
#!/bin/sh
value=`compare -metric rmse -subimage-search 2.jpg 1.jpg null: 2>&1 | sed -n 's/^.*(\(.*\)).*$/\1/p'`
test=`convert xc: -format "%[fx:$value<0.022?1:0]" info:'
if [ $test -eq 1]; then
convert 4.jpg oldid.jpg
else
convert 4.jpg ...
