Mainly cosmetics, e.g. the first adds timings and options(echo=TRUE) and 
generates a suitably named outfile.  [Also sets --restore --save which 
you then override.]

It used to set --gui=none to avoid the overhead of loading the X11 module.

More importantly, the first redirects stderr and yours does not, but see 
my reply to the OP's other thread for a closer equivalent.
