Need help in bash script and awk command

I need a bash script to print directory names and file names recursively . For example: i have a directory structure like:

/earth/plants/flowers/rose/rose.jpg.
/earth/plant/fruits/apple/apple.jpg.
/earth/animals/carni/lions.jpg
/earth/animals/herbi/omni/dog.jpg

Now I need to list this files and folders like this — I mean my O/P should be,

planet=earth
category=animal (plant) 
sub cat = carni 
name = lion.jpg.

In some places I have additional directories also.like /earth/animals/carni/jungle/lions.jpg.

Then I need to display that lions.jpg file size also.

This may get you part of the way there…

find /earth | sed -e 's/\// /' | awk '{ print "planet = " $1 "\ncategory = " $2 "\nsubcat = " $3 "\nname = " $4}'

I’ll break it apart so others may improve / modify

find /earth

find simply dumps a listing of all the contents of the /earth directory

sed -e 's/\// /'

I’m replaced all the forward slashes with the space character so I can easily break apart the words. I could do without this step by telling awk to use the forward slash as the delimiter, but this may (or may not) by useful to future revision, so I leave it.

awk '{ print .... }'

I’m telling awk to print the input it’s given with the various categories listed in the question. $1 means the first token. $2 the second token and so on. awk understands lines breaks as well “\n”.

I’m not sure what to do if you have several subcategories, however this should get you close.
