我想備份今天生成的文件，用set失敗。求助ing

xcsars

-rw-r----- 1 oracle dba  556 Dec 30 15:58 test.log.bak
-rw-r----- 1 oracle dba  556 Dec 30 16:08 test.log
-rw-r----- 1 oracle dba 1427 Dec 30 18:25 rman_bak.sh

-rw-r----- 1 oracle dba    0 Jan  6 11:37 111.txt
-rw-r----- 1 oracle dba    0 Jan  6 11:37 222.txt

我想實現(xiàn)一個功能，備份今天生成的文件，用下面的腳本沒有辦法獲取到文件

腳本如下


set $(date)

V_Month=$2
V_Day=$3
V_MoDy=$2" "$3
ls -lrt |grep ^-|grep "$V_MoDy"|awk '{print $9}'|xargs tar -cf backup_`date +%Y%m%d`.tar


ls -lrt |grep "$V_MoDy" 沒有結(jié)果。

date的顯示格式。

    用 find 吧，比你那個方便多了。

find - search for files in a directory hierarchy

SYNOPSIS
       find [-H] [-L] [-P] [path...] [expression]
for example：
       -anewer file
              File  was last accessed more recently than file was modified.  If file is a symbolic link and the -H option or the -L option is
              in effect, the access time of the file it points to is always used.

       -atime n
              File was last accessed n*24 hours ago.  When find figures out how many 24-hour periods ago the  file  was  last  accessed,  any
              fractional part is ignored, so to match -atime +1, a file has to have been accessed at least two days ago.

       -cmin n
              File status was last changed n minutes ago.

       -cnewer file
              File  status  was  last changed more recently than file was modified.  If file is a symbolic link and the -H option or the -L
              option is in effect, the status-change time of the file it points to is always used.

       -ctime n
              File status was last changed n*24 hours ago.  See the comments for -atime to understand how rounding affects the  interpreta-
              tion of file status change times.


例子：
              find . -mtime 1  -exec ls -l '{}' \;           #我這樣好像只是把今天內(nèi)的所有文件都列出來了
