根据命名模式删除文件夹

因此，假设它们都在同一目录中。

我要指出的是，我测试了该脚本的一部分，但不是全部，所以您可能要在实际运行它之前进行一些修改/测试，以免最终删除所有目录。

# Find the date 30 days ago.
recent_dirs=`date -d "-30 days" +%d-%m-%Y`
rec_month=`echo "${recent_dirs}" | cut -d '-' -f2`
rec_day=`echo "${recent_dirs}" | cut -d '-' -f1`
rec_month=`echo "${recent_dirs}" | cut -d '-' -f3`

# Go to your "home" directory for the directories.
cd /path/to/home/directory

for i in *; do
    # Check to see if the element is a directory.
    if [ -d "${i}" ]; then
        echo "Processing directory - ${i} ... "
        # Determine the date information for the directory.
        cur_month=`cat "${i}" | cut -d '_' -f1`
        cur_day=`cat "${i}" | cut -d '_' -f2`

        # Keep all directories from the first of the month.
        if [ "${first_day}" -eq "01" ]; then continue; fi

        # Keep all directories from the current month and current year.
        if [ "${cur_month}" -eq "${rec_month}" ]; then
            if [ "${cur_year}" -eq "${rec_year}" ]; then continue; fi
        fi

        # Keep all directories from last month, but newer than today's DAY.  I'm not 
        #  a pro at bash arithmetic, so you might have to goof with the subshell 
        #  math to get it to work quite right.
        if [ "${cur_month} -eq $(( expr $rec_month - 1 )) ]; then
            if [ "${cur_day}" -gt "${rec_day}" ]; then continue; fi
        fi

        # So at this point, I think we've dealt with everything, except the case where
        #  the current month is January, and so you're trying to save December's 
        #  directories from last year.  I think this handles it.

        if [ "${rec_month}" -eq "01" ]; then
            if [ "${cur_month} -eq "12" ]; then
                if [ "${cur_year}" -eq $(( expr ${rec_year} - 1 )) ]; then continue; fi
            fi
        fi

        # If we haven't stopped processing the directory by now, it's time 
        #   remove our directory.
        rm -fr "${i}"
     else

这样做不会处理31天的几个月，因此在很多情况下您可能会保存31个目录，而不是30个目录。我的印象是，您正在尝试进行清理，而不是严格遵守常规，但是...
