问题描述

我的文件夹中有很多文件，文件名都像

I have a lot of files in folder with filenames like

20190618_213557.mp4

..

我需要根据文件名更改创建日期和时间20190618_213557 = YYYYMMDD_HHMMSS在终端中使用bash脚本

I need to change creation date and time based on filename20190618_213557=YYYYMMDD_HHMMSSusing bash script in terminal

推荐答案

MACOS Uses touch -mt to change file creation/modification time. Here is the script:

    #!/bin/bash
    FILES="/Users/shakirzareen/Desktop/untitledfolder/*"
    for f in $FILES         ## f = full path + filename
    do
        t="${f##*/}"            ##remove folder path from filename
        t2="${t//_}"            ##remove _ from filename
        t3="${t2%%.*}"          ##remove file extension part
        touch -mt "$t3" $f  ##set creation and modification time of file
    done
