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 You ...

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: \( -size 70x46 xc:red \) null ...

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.jpg ...

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:

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. http://i46.tinypic.com/14142ls.jpg I think ...

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 ...
