$ set var=`echo 3284`; echo $var

  or

$ export var=`echo 3284`
$ echo $var



The first way is okay if you're in a script rather than
the command-line, as the variable will be in scope throughout
the rest of the file (but not outside it). 'export' makes
the variable global.
'man bash' is one of the best manpages in my opinion;
read the whole thing and be happy later.
