linux下用脚本将目录内的文件分类到各自的创建年份（如2023）或年月份（如2023/202308）目录内

第一个if判断语句中判定只有是文件的时候才执行mv操作，并忽略一些特定
第二个if判断目录不存在时创建目录
最后mv文件到目录内
脚本执行前目录内容：
2022-01-file
2023-02-file
脚本执行后目录内容：
2022
|2022-01-file
2023
|2023-02-file

#!/bin/bash
#for line in `ls -lhrt`
for line in `ls -lhrt | grep -v moveToModifyDir.sh | awk -F " " '{ print $9}'`
do
    if [ -f "$line" ] && [ "$line" != "" ] \
        && [ "$line" != "." ] \
        && [ "$line" != ".." ] \
        && [ "$line" != "desktop.ini" ] \
        && [ "$line" != "@eaDir" ] \
        && [ "$line" != "Thumbs.db" ]
    then
        modifyYear=`stat $line | grep Modify | awk -F " " '{ print $2 }' | awk -F "-" '{ print $1 }'`
        modifyMonth=`stat $line | grep Modify | awk -F " " '{ print $2 }' | awk -F "-" '{ print $2 }'`
        echo "file: $line modifyYear is: $modifyYear modifyMonth is: $modifyMonth"
        realDir="${modifyYear}${modifyMonth}/"
        if [ ! -d $realDir ]
        then
            echo "$realDir not exist, ready to mkdir"
            mkdir $realDir
        elif [ -d $realDir ]
        then
            echo "$realDir exist..."
        fi
        echo "realDir is: $realDir"
        mv $line $realDir
    fi
done

第二个脚本是先创建年份目录，再创建年+月子目录，并将文件移动到子目录内
脚本执行前目录内容：
2022-01-file
2023-02-file
脚本执行后目录内容：
2022
|2022-01
|2022-01-file
2023
|2023-02
|2023-02-file

#!/bin/bash
for line in `ls -lhrt | grep -v "moveToModifyDir.sh\|moveToYearDateDir.sh" | awk -F " " '{ print $9}'`
do
    if [ -f "$line" ] && [ "$line" != "" ] \
        && [ "$line" != "." ] \
        && [ "$line" != ".." ] \
        && [ "$line" != "dl.sh" ] \
        && [ "$line" != "desktop.ini" ] \
        && [ "$line" != "@eaDir" ] \
        && [ "$line" != "urls.txt" ] \
        && [ "$line" != "Thumbs.db" ]
    then
        modifyYear=`stat $line | grep Modify | awk -F " " '{ print $2 }' | awk -F "-" '{ print $1 }'`
        modifyMonth=`stat $line | grep Modify | awk -F " " '{ print $2 }' | awk -F "-" '{ print $2 }'`
        echo "file: $line                       modifyYear is: $modifyYear modifyMonth is: $modifyMonth"
        realDir="${modifyYear}/${modifyYear}${modifyMonth}/"
        echo "realDir is: $realDir"
        if [ ! -d $realDir ]
        then
            echo "\"$realDir\" dir not exist, ready to mkdir: $realDir"
            mkdir -p $realDir
        elif [ -d $realDir ]
        then
            echo "\"$realDir\" dir exist"
        fi
        mv $line $realDir
    fi
done
