[nzlug] bash help - for loop listing dirs

[Howard]

Hi, I'm after some bash script help please...

I have a for loop which I thought would need to be thus:

for i in `ls -1`
do
cd $i
blah...

I need to recursively list dirs, then do some stuff.  Some dirs have 
spaces in their names, and these are listed as separate words in the 
loop... causing the dir names to be incorrect (breaks in for loop occur 
at spaces).

I have briefly googled and had a suggestion to use IFS or maybe tr to 
changes the spaces to something else first... and not being a skilled 
basher can someone give me an example please of an 'accepted' way to do it?

Thanks
H
