How can I use sed to alter the results of find and pass the results to cp?

Question

In solaris, I'd like to copy all files found by the find command to a slightly different path. The following script basically executes cp for each file found by find. For example:

cp ./content/english/activity1_compressed.swf ./content/spanish/activity1_compressed.swf
cp ./content/english/activity2_compressed.swf ./content/spanish/activity2_compressed.swf
...

#!/bin/bash

# Read all file names into an array
FilesArray=($(find "." -name "*_compressed.swf"))

# Get length of an array
FilesIndex=${#FilesArray[@]}

# Copy each file from english to spanish folder
# Ex: cp ./english/activity_compressed.swf ./spanish/activity_compressed.swf
for (( i=0; i<${FilesIndex}; i++ ));
do
    source="${FilesArray[$i]}"

    # Replace "english" with "spanish" in path  
    destination="$(echo "${source}" | sed 's/english/spanish/')"

    cp "${source}" "${destination}"
done

exit 0;

It seems like a bit much and I wonder how to use sed in-line with the find and cp commands to achieve the same thing. I would have hoped for something like the following, but apparently parentheses aren't acceptable method of changing order of operation:

find . -name *_compressed -exec cp {} (echo '{}' | sed 's/english/spanish/')

Answer 1

There are easier ways, but for portability sake we can use a bit of forking and backticks:

find . -name *_compressed -exec sh -c 'cp {} `echo {} | sed 's/english/spanish/'`' \;

Answer 2

I'd use the backtick: you'll find more upon it here (backtick is at chapter 3.4.5).

Basically when you enclose a command between backticks the command itself will be substituted in his output.
