循环遍历名称中有空格的目录

Question

I am sorry if someone asked this question gain, but I didn't find a solution which worked for me.

I wrote a small bash script, which works with normal folders. It should run a command for every Subfolder. But if there is a space in a Folder Name, there is a problem.

If there is a Folder called "New Folder" in /share/Download, the script will try to access to the folder "/share/Download/New" (instead of "New Folder")

i also tried with echo "$d"

    for d in `find /share/Download -mindepth 1 -type d`
do
    echo
    echo $d
    curl http://localhost:2345/api/command -X POST -d '{"name": "something", "path": "'"$d"'"}' --header "X-Api-Key:123456789"
    echo
done

Answer 1

Shell is doing word splitting on find 's output and that is the reason you are having the trouble.

Use process substitution to properly read the output of find :

while read -r d; do
  # your logic
done < <(find /share/Download -mindepth 1 -type d)

Even better, make find emit NUL terminated output so that directories that have a newline in them would be handled appropriately as well:

while read -r -d '' d; do
  # your logic
done < <(find /share/Download -mindepth 1 -type d -print0)

This answer can help you further.

Answer 2

I allready found the problem and a solution after more research.

for d in isn't whitespace save.

The following code did the trick:

    find  /share/Download -mindepth 1 -type d|while read fname; do
  curl http://localhost:1234/api/command -X POST -d '{"name": "something", "path": "'"$fname"'"}' --header "X-Api-Key:123456789"
done
