Question

I have written this script as a module in installing postgres and this is to show the user that the database has been created and get his/her input as to they see the database was created. When I run the script, I get the error

./dbtest: line 39: [: missing `]'

I have tried adding ” ” around yes and ” around yes and I can’t figure out what is missing. The script is as follows

#   
#
# Check to make sure the database was created and who is the owner
#
#
 if [ -f showdb ];

 then 
      cp showdb /home

 else
      echo " show database file is missing "

fi

if [ -f /home/showdb ];

 then
       su - postgres -c '/home/showdb'

       echo " Do you see the data name created listed above? "
       echo " "
       echo " Type yes or no (type out the whole word please) "
       echo " "
       read dbawr

            if [ $dbawr == yes && $dbawr == Yes ];

                then 

                     echo "Great!"
                     exit

                else
                     echo " Please contact tech support "
                     pause " Press [CTRL] [Z] to exit the program now " 
              fi

  else

         echo " File Missing!!"

fi

What am I missing in this script?

Thanks!

You can’t use the boolean && operator withing the single brackets conditional [ test = test ]. If you’re using bash (or a similar shell), the preferred syntax is to use the double brackets:

[[ this == this && that == that ]]

If you’re worried about portability, then you should stick with the single brackets, but use them like so:

[ this = this ] && [ that = that ]

Note that I didn’t use the double equals (==). That’s not posix compliant either.
