Shell variable issue when trying to mkdir

Question

Any ideas what is wrong with this code?

CLIENT_BUILD_DIR=\"~/Desktop/TempDir/\"

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


        

Answer 1

The quotes prevent the expansion of ~.

Use:

CLIENT_BUILD_DIR=~/Desktop/TempDir/

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

Answer 2

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

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

Answer 3

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