参考http://www.361way.com/chang-file-time/1632.html
一:查看时间
1:查看文件的具体时间信息
File: `probn‘ Size: 2 Blocks: 8 IO Block: 4096 regular file Device: 803h/2051d Inode: 913948 Links: 1 Access: (0755/-rwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2016-10-31 20:00:00.000000000 +0800 Modify: 2016-10-31 20:00:00.000000000 +0800 Change: 2016-10-31 15:22:32.020285558 +0800
Access:访问时间 cat more less
Modify:修改内容时间 vim
Change:修改文件属性的时间 chmod
2:用ls的方法查看
Access time 访问时间 :atime
ls -l --time=atime kkk
Modification time 修改时间:mtime ls -l查看的时候默认的就是修改时间
ls -l
status time 状态时间 :ctime
ls -l --time=ctime kkk
二:修改文件的时间
touch 命令:
touch 一个已经存在的文件,只会修改时间
-a 修改文件的访问时间
[[email protected] allapk]# touch -a -d "2009-11-11" kkk [[email protected] allapk]# stat kkk File: `kkk‘ Size: 0 Blocks: 0 IO Block: 4096 regular empty file Device: 803h/2051d Inode: 913948 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2009-11-11 00:00:00.000000000 +0800 Modify: 2016-10-31 09:00:00.000000000 +0800 Change: 2016-10-31 15:55:30.295285265 +0800
-m 修改文件的修改时间
[[email protected] allapk]# touch -m -d "2010-10-18" kkk [[email protected] allapk]# stat kkk File: `kkk‘ Size: 0 Blocks: 0 IO Block: 4096 regular empty file Device: 803h/2051d Inode: 913948 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2009-11-11 00:00:00.000000000 +0800 Modify: 2010-10-18 00:00:00.000000000 +0800 Change: 2016-10-31 15:56:11.510285082 +0800
-d 同时修改访问时间和修改时间
[[email protected] allapk]# touch -d "2008-10-10" kkk [[email protected] allapk]# stat kkk File: `kkk‘ Size: 0 Blocks: 0 IO Block: 4096 regular empty file Device: 803h/2051d Inode: 913948 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2008-10-10 00:00:00.000000000 +0800 Modify: 2008-10-10 00:00:00.000000000 +0800 Change: 2016-10-31 15:54:00.235285047 +0800
3:把后面文件夹的时间修改成和前一个文件一样,change这个时间还是自己的
touch -acmr kkk lll
