Re: [ferret_users] Question about using script

[Ryo Furue <furue@xxxxxxxxxx>]

Hello Ming,

| #!/bin/ksh -x
| 
| ferret<<EOF

It seems that the problem has something to do with how
ferret reads the standard input.

I've confirmed that a short script like

   #!/bin/ksh
   ferret<<EOF
   set data "somedata.nc"
   fill/k=1/l=1 var
   quit
   EOF

works.  I've also tested your script and reproduced your error
messages.  I've also found
1) that when I have only two "set data . . . " lines, the script
   works;
2) that a third "set data . . . " mangles ferret's output;
3) that even comment lines affect the results.

As to point (3), try add lines entirely consisting of "!" symbols
like "!!!!!!!!!!!" and you'll see differences.

All these seem to point toward how ferret buffers and reads
the standard input.
