Smile recursive execution of function in subdirectories


I have this type of bash script to execute a function recursively in the subdirectories (the real one is more useful than the one in the example below ):
Code:
#!/bin/sh
hereiam ()
{
echo "Here I am now:" $(pwd)
}

find . -type d | while read dir; do hereiam; done
I am finding some problems with the function but I don't know if it is due to the function itself or by the way that find | while ( or find | xargs for that sake) operate.

How can I execute the function recursively without 'find'?
Thanks!

Osio

dirs=`ls -d */`
cd $1
hereiam
cd $2
hereiam

seems to work but it needs some iteration and test construct...

Try with:
Code:
#!/bin/sh
hereiam ()
{
echo "Here I am now:" $(pwd)
}

find . -type d | while read dir ; do ( cd "$dir" ; hereiam ) ; done

Yes, my function in real life does need to be at the working directory, so
Code:
cd "$dir"
is what I needed.
Thank you, primo!
