Question

你好我有脚本问题，我想删除超过7天的文件，但我做错了:)但是不起作用。提前感谢您的帮助

 #!/bin/bash

# sudo apt-get install pydf
#pydf

# source 
DST="/mnt/share/backup"

#find TIF
FINDFILE=*.TIF


if ! [ -f "$DST/$FINDFILE" ]; then
    echo "no file in: $DST"
    find $DST -type f -mtime +7 -name '*.TIF'
    if ! [ "$?" = "0" ]; then
       echo "ERROR  $DST/"
       exit 200
    fi
else    
    echo "file exist"
    echo "older than 7 days wiil deleted "

    find $DST -type f -mtime +7 -name '*.TIF' -execdir rm -- {} \;
    if ! [ "$?" = "0" ]; then
       echo "ERROR : $DST"
       exit 200
    fi
fi

如果存在文件剂量，则find $DST -type f -mtime +7 -name '*.TIF'如果存在find $DST -type f -mtime +7 -name '*.TIF' -execdir rm -- {} \;

OUTPUT终端

如果没有tiff退出，

开头是错误if ! [ -f "$DST/$FINDFILE" ]; then。

问题已解决

find path/to/directory -time +7 | xargs rm
