[SAC-HELP] calling sac commands within shell scripts

[Derek Schutt]

  Hi Januka,

Here's one way to do it.   This is from a bash script that invokes sac 
to change the "a" and "f" headers:

echo -e "r $sacfile \n ch a $a_time \n ch F $F_time \n wh \n exit" | sac

I'd bet there are much more elegant ways to do it too.
