Shell variable issue when trying to mkdir

Any ideas what is wrong with this code?

CLIENT_BUILD_DIR="~/Desktop/TempDir/"

if [ ! -d $CLIENT_BUILD_DIR ]
then
   {
      mkdir $CLIENT_BUILD_DIR
   }
fi

I get the error: mkdir: ~/Desktop: No such file or directory.

Obviously the directory is there and the script works if I replace the variable with ~/Desktop/TempDir/

mkdir ${CLIENT_BUILD_DIR} will do. No directory will be created if it already exists.

The ~ character is not reinterpret when used in a variable.

You can use CLIENT_BUILD_DIR="$HOME/Desktop/TempDir/" instead.

The quotes prevent the expansion of ~.

Use:

CLIENT_BUILD_DIR=~/Desktop/TempDir/

if [ ! -d "$CLIENT_BUILD_DIR" ]
then mkdir "$CLIENT_BUILD_DIR"
fi
