Problems with the control design

Question

Good evening (or day. Whichever)! I ran into a problem while writing a bash script. I have the code

#!/bin/bash
echo "Available options:"
echo "1. text"
echo "2. exit"
read var1
echo

if [[$var -ge 0]]; then
   echo "hello world"
elif [[$var -ge 1]]; then
     echo "good bye"
else
    echo "error"
fi

and all the time it puts the emphasis on the operator

./proba3.sh: line 9: [[: command not found
./proba3.sh: line 11: [[: command not found

I tried many variations of the branching operation, but still get the same error. I will be very glad for advice or hints on how to fix this error. Thanks in advance

You need spaces inside the brackets.
Also you misspelled the variable name.
Finally, you should probably test for equality not ge

Fixed:

#!/bin/bash
echo "Available options:"
echo "1. text"
echo "2. exit"
read var
echo

if [[ $var -eq 1 ]]; then
   echo "hello world"
elif [[ $var -eq 2 ]]; then
     echo "good bye"
else
    echo "error"
fi
