)
#!/bin/sh
ssh host cmd &> log

#!/bin/sh
ssh host cmd > log 2>&1
&>
is a bash and ksh extension for redirecting both stdout and stderr. In dash and POSIX sh, use 2>&1

If you only intend to target shells that supports this feature, you can change the shebang to a shell that guarantees support, or ignore this warning.
You can use # shellcheck disable=SC3000-SC4000
to ignore all such compatibility
warnings.
