Question

我需要在bash中执行以下操作：

转到该文件夹并递归检查当前文件夹中的新文件，新文件的上次更新时间为＆gt; = D - 7天，记住每个新文件的名称

我会这样做：find ./ -type f -ctime -7 -exec ls {} \; > new.files

然后我需要转到上一个目录cd ../并查找创建的新文件夹，这些文件夹不是来自我的白名单（文件夹列表），并且在过去7天内进行了更新。如果我找到任何目录，我需要去这个目录并检查新文件，就像我之前做的那样（find ./ -type f -ctime -7 -exec ls {} \; > new.files.from.new.dir）

结果我应该用新文件发送新文件列表和新目录列表（不是白名单）。

提前感谢您的帮助！

这是完成的，精致的脚本！请注意重定向的很酷用法。：）

#!/bin/bash

#export for use in shells!
export CURR_DIR=`pwd`

RESULTS_LOC=$CURR_DIR
WHITELISTS_LOC=$CURR_DIR
PERIOD=0.1
#Before X number of days... can be fractional
#also, needed for shells, hence source
export FTIME=-$PERIOD

#Make list of new files in current dir.
if [ -e $WHITELISTS_LOC/whitelist.files ]; then

    # What's going on here:
    #
    # 1. Inner shells change to current dir., then search for change files, w
    #    all three diff. types of mods.
    #
    # 2. The output is then sorted, and piped to a uniq -d to give only single 
    #    items for all duplicates.  This is then merged with a duplicate set 
    #    of calls that gives all uniq items via uniq -u.
    #
    # 3. Lastly, we apply any pertinent grep file filters to remove (-v -f)
    #    as in the case of the whitelist, or to select (as in the case of 
    #    our new dir.
