Question Problems with find | ls within a for statement
Hello,

Code:
for dir in `find /root/test -type d` ;do
    echo "$dir"
done

for dir in `ls -1d /root/test/*/` ;do
    echo "$dir"
done

If there's a directory with spaces in name, it does echo each word of that dir separately... solution?

Code:
mkdir "test"
cd test
mkdir "example_1_2_3"
mkdir "example 1 2 3"

Example results:

Code:
/root/test
/root/test/example
1
2
3
/root/test/example1_2_3

Code:
for dir in "`find /root/test -type d`" ;do
    echo "$dir"
done

for dir in "`ls -1d /root/test/*/`" ;do
    echo "$dir"
done

Nope that doesn't work either, try echo "Found $dir, yeah!"

Code:
Found: /root/test
/root/test/example 1 2 3
/root/test/example1_2_3, yeah!

Maybe this will do it for you:
Code:
find . -print0 | xargs -0i echo "Found {}, yeah"

To get each line separately you need to 'read' each line from the variable
Code:
for dir in "`find ./ -type d`";do
  echo "$dir" | while read line; do
    echo "Found: $line ,yeah!"
  done
done

That's a needlessly convoluted way of doing:
Code:
find . -type d | while read -r line; do
    echo "Found: $line ,yeah!"
done

Better still, the following is safe for use on any legal filenames, including abominations that include a newline in their name:
Code:
find . -type d -exec sh -c '
    for dir; do
        echo "Found: $dir ,yeah!"
    done
' sh {} +
