+In Linux the command:
+
+ps -aux
+
+Means show 'all processes for all users'. You might be wondering what the x means? The x is a specifier that means 'any of the users'. So you could type this:
+
+ps -auroot
+
+Which displays all the root processes, or
+
+ps -auel
+
+which displays all the processes from user el. The technobabble in the 'man ps' page is: "ps -aux prints all processes owned by a user named 'x' as well as printing all processes that would be selected by the -a option.
