How to add the output of two commands info a file?

Question

I simply want to append the outputs of two command which are ps -A and du into a file called "info"

This is what I've got:

ps -A ; du > info

However, it only adds du into the file. What am I getting wrong?

No need to use a subshell (another process) :

 { ps -A ; du; } > info
 # ^
 # |
 # mandatory (in this one liner case)

or

{
 ps -A
 du
} > info
