batch remove the last 9 characters from folders names?

[sohlinux]

Hello, How can I batch remove the last 9 characters from folders names?

for example I have many folders as follows

jhgtyuioplgdrtghnbjk after will be jhgtyuioplg

yt00:hnbfdkk ioiuyui after will be yt00:hnbfdk

qw jh dd0ddyyt:jkopi after will be qw jh dd0dd

thanks

for d in *; do mv "$d" "${d%?????????}"; done

or

rename 's/.{9}$//' *

if the folders are mixed with files, then some condition to narrow down is required eg

[[ -d "$d" ]] || continue

edit: it's possible to glob dirs only with */ but it would require accounting for that additional char (eg 10x'?' / .{10})
