创建文件并设置权限

#!/bin/sh
#written by dmer

corepath=/corefiles

#echo $corepath

if [ -d $corepath ];then

#echo aaaa

if [ $(state -c %a $corepath) -ne 777 ]; then

#echo bbbb

chmod 777 $corepath

fi

else

#echo dddd
mkdir $corepath
chmod 777 $corepath

fi

exit 0

解释: -d $corepath  存在并且是文件夹

$(state -c %a $corepath) -ne 777 传入的文件状态权限八进制 不等于777
