$ cat << EOF > test.sh
if [ "magic" == "\$1" ]; then
    echo "Argument is magic."
$ /bin/dash test.sh
[: 3: magic: unexpected operator
$ /bin/dash test.sh magic
[: 3: magic: unexpected operator
$ sed -e 's/==/=/' -i test.sh
$ /bin/dash test.sh
$ /bin/dash test.sh magic
Argument is magic.
$ /bin/bash test.sh
$ /bin/bash test.sh magic
Argument is magic.

dash is a posix compatible shell. As most people use bash as their
shell, incompatibilies with posix shell often go unnoticed for a long
time. A script should however either specify /bin/bash as interpreter
or adhere to the shell language given in POSIX.
