find $BACKUPDIR/test1 -mtime +6 -exec rm -rf {} \;

当我运行上面的测试脚本时,如果该目录test1
不存在,则运行正常。但是,如果该目录test1
在那里,即使它删除了该目录,我也会收到以下错误。
Test ./testFind.sh
find: ‘./test1’: No such file or directory
Error occurred in script at line: 20
Line exited with status: 1
我怎样才能停止错误?
答案1
-prune
在要删除的目录上使用以告诉find
不要尝试在其中查找文件:
find $BACKUPDIR/test1 -mtime +6 -prune -exec rm -rf {} \;
