That was my thought too.

Note you can sometimes get fancy and do away with temp variables if the 
output is intended to be a single line. Like:

printf "%3d %15s %s\n" \
  $(foo) \
  `bar`  \
  $(baz)

Where `` and $() are the command substitution operators [1], I prefer 
the POSIX $() one.  And foo, bar, and baz are some one-liners or 
whatever that return just the bit of data you want in that slot on that 
line.

It depends.  Do whatever is easier to read and maintain...

"Microsoft Tax" = the additional hardware & yearly fees for the add-on
software required to protect Windows from its own poorly designed and
implemented self, while the overhead incidentally flattens Moore's Law.
