Bash delete directories except that one

Ran into a scenario where I needed to delete all subdirectories of target except target/keepme/. So I want rm -rf target/subdir1 target/subdir2 ... target/subdirN with one directory omitted. I want to use grep to remove the directory I want to keep from the list so something like this should work:

  1. Print the list of directories echo target/*/
  2. Flip space separator to newline  tr " " "\n"
  3. Remove the line for the directory to keep grep -v keepme
  4. Flip newline back to space  tr "\n" " "
  5. Run rm -rf on the results from steps 1-4

As a 1-liner:

rm -rf $(echo target/*/ | tr " " "\n" | grep -v keepme | tr "\n" " ")

Noting it in case I need to do it again someday ;)

How about this one:

find target/* ! -iname keepme -print0 | xargs -0 rm -rf

this works for me

A universal message I suppose, not giving up is the formula for success I think. Some things take longer than others to accomplish, so people must understand that they should have their eyes on the goal, and that should keep them motivated to see it out til the end.
