Weird folder names in Raspberry Pi file list

raspi occasionally creates weird folders under /root with incomprehensible names:

drwx------ 3 root root 4.0K Jul 7 2022 ''$'\033''[?25h'$'\033''[?7h'/ 

You can’t easily delete the folder with rm -rf.

First, you need to find the inode to the folder:

# ls -ihalF
total 80K
15     drwx------ 11 root root 4.0K Apr 18 10:42 ./
2      drwxr-xr-x 18 root root 4.0K Jul 21 08:34 ../
524545 drwx------ 3 root root 4.0K Jul 7 2022 ''$'\033''[?25h'$'\033''[?7h'/

So in this case the inode is 524545

Use ‘find’ to get rid of it:

find . -maxdepth 1 -type d -inum 524545 -exec rm -rf {} \;

Folder is now deleted
