Another solution along the same lines is:
---%<----
#!/bin/sh
action()
{
# Put the code you would like to run in each subdir in the body of this
# function (below this comment, but above the next "}")
echo "I am in `pwd`"
}
make_dir_list()
{
unset mydirs
for file in * ; do
[ -d $file ] && mydirs="$mydirs $file"
done
echo $mydirs
}
traverse()
{
if [ $# -eq 0 ] ; then
action
return
else
# visit the root first (in pre-order)
# can also move the action line to after the for loop to traverse in post-order, sort of
action
for subdir ; do
cd $subdir
traverse `make_dir_list`
cd ..
done
fi
}
traverse `make_dir_list`
