How to check a directory has a read/write permission

问题

I have a directory as shown

d-wx--x--x 2 bcheudev bcheudev  4096 Jun 18 06:16 test

which shows the directory does not have read permission.

But when i check the same through shell script it's giving result as dir test has read permission.

export IN_DIR=$MMHOME/test   
if [ -d ${IN_DIR}  ]    
then    
   if [ ! -r ${IN_DIR} ]    
   then    
      echo "${IN_DIR} Directory is not readable.">>$log_name    
      exit 255   
   fi    
else    
   echo "${IN_DIR} Directory does not Exists.">>$log_name
   exit 255    
fi

inside second if it's not going.

Please help

Remember that root will always have read permissions.

I think that your condition is incorrect. Try with :

if ! [[ -r ${IN_DIR} ]]
  then
    echo "${IN_DIR} Directory is not readable.">>$log_name
    exit 255
fi
