你试试用\r\nrm -f `find .....`\r\n来运行一下看看

试过了 不行的\r\n\r\n# rm -f \'find sjournal -ctime +19\'\r\n# find sjournal -ctime +19\r\nsjournal/20040625.001\r\nsjournal/20040626.001\r\n# rm -f \'find sjournal -ctime +19 -print\'\r\n# findd sjournal -ctime +19\r\nksh: findd:  not found.\r\n# find sjournal -ctime +19\r\nsjournal/20040625.001\r\nsjournal/20040626.001

ok了\r\n谢谢   此引号非彼引号\r\n\r\n# rm -f `find sjournal -ctime +19`\r\n# find sjournal -ctime +19

最初的写法 我是查man 学来的\r\nman中的例子都出同样的错\r\n为什么？

`这个符号的作用就是把里面命令的输出当作别的命令的参数\r\n我一般都是这么用的，AIX的man比较垃圾，别全信

runtimel

find /  -atime +3 -exec \\ rm {} \\;

runtimel

man 应该是非常好的助手，请大家仔细阅读

liugw

find . -ctime +3 -exec rm {} \\;

浪花飞鱼

$find  . -mtime 3 -exec rm \\{}  \\;
