Say I have folders:
img1/
img2/
How do I delete those folders using regex from Linux terminal, that matches everything starts with img?

To permanently remove a directory in Linux, use either rmdir or rm command: For empty directories, use rmdir [dirname] or rm -d [dirname] For non-empty directories, use rm -r [dirname]
Delete a Directory ( rm -r ) To delete (i.e. remove) a directory and all the sub-directories and files that it contains, navigate to its parent directory, and then use the command rm -r followed by the name of the directory you want to delete (e.g. rm -r directory-name ).
Use the rm command to remove files you no longer need. The rm command removes the entries for a specified file, group of files, or certain select files from a list within a directory. User confirmation, read permission, and write permission are not required before a file is removed when you use the rm command.
There are two Linux commands you can use to remove a directory from the terminal window or command line: The rm command removes complete directories, including subdirectories and files. The rmdir command removes empty directories.
Use find to filter directories
$ find . -type d -name "img*" -exec rm -rf {} \;
As it was mentioned in a comments this is using shell globs not regexs. If you want regex
$ find . -type d -regex "\./img.*" -exec rm -rf {} \;
