No, with the spaces around the '=' and the dollar before the variable
name this actually is a test not an assignment. But using double '=' is
more clear, agreed. Try

#!/bin/sh
C="no"
if [ $C = "yes" ]; then
    echo "1: $C"
fi
if [ $C="yes" ]; then
    echo "2: $C"
fi

This will return:
2: no

Bash is very peculiar ;)

Regards,
Leonard.
