find 除了某个文件之外，删除所有其他文件 (-not -name、-delete)

1.

除了 HoloCircleView.java 文件，其他文件全部删除

find . -type f -not -name "HoloCircleView.java" -delete

find . -not -name "HoloCircleView.java" -delete

除了 HoloCircleView.java 和 current.tx之外，其他文件和目录全部删除

find . -not -name "HoloCircleView.java" -not -name "current.txt" -delete

2.

递归删除空目录

~/deleteEmptyDir.sh

#!/bin/bash

# des: delete empty directories recursive

deleteempty() {

    find ${1:-.} -mindepth 1 -maxdepth 1 -type d | while read -r dir

    do

        if [[ -z "$(find "$dir" -mindepth 1 -type f)" ]] >/dev/null

        then

            echo "$dir"

            rm -rf ${dir} 2>&- && echo "Empty, Deleted!" || echo

"Delete error"

        fi

        if [ -d ${dir} ]

        then

            deleteempty "$dir"

        fi

    done

}
