Re: [ferret_users] Question about using script

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Ming,
In addition to the previous replies, I'd like to add that a direct way 
to "pipe" a script to Ferret is to use the -script command-line option

  ferret -script scriptname.jnl

If there are arguments to the script, they come after the script file name.
