Folder permissions to delete

I am using the below command to delete files from directories and subdirectories
find /test/abc/xyx -type f -mtime +7 -exec rm -f {} \;

there are some subfolders in xyx for which i don't have permission to delete.

Is there a way i can check the permission of the folder first and then delete the files.
Thanks in advance

find can't react differently depending on what folder it's inside. You could make a big complicated program to find writable directories and delete every file inside them, or just ignore the errors with 2> /dev/null.

There are lots of methods of finding things with certain permissions with find, but what functions you have depends on your system. What is your system? What is your shell?

Just so that I am clear, are you trying to delete folders? I am asking because rm -f won't work on folders.

If you have GNU find that makes things a lot simpler, it supports -maxdepth to prevent recursion.

# Find every writable directory inside /path/to/base
find /path/to/base -type d -writable |
while read DIR
        # Print all files inside writable directories.
        find "$DIR" -mindepth 1 -maxdepth 1 -type f

        # feed the list into xargs, which turns it into rm -f file1 file2 file3 ...
done | xargs echo rm -f

Remove the 'echo' from xargs once you've tested that it really does what you want.
