Hi Giorgio,
Another method for sending Ferret/PyFerret a set of commands is to use the -script option on startup.
> pyferret -script my_script.jnl [arguments]
This is generally more flexible than piping commands. The startup option -batch for Ferret or -nodisplay for PyFerret are also useful when you don't want to have graphics windows display. Note that -script must appear last among command line switches so that the script arguments will be parsed correctly.

Compare this line with the one in the original shell script:
ferret << STOP. . .define symbol ii `i`. . .STOP
Where did `i` go?
In the shell script as well as in the ferret script, the backquote construct is evaluated. In the above shell script, the shell tries to run a command named "i". It fails and is replaced with an empty string. I suppose you saw this error message on your screen
. . . i: command not found
To prevent the shell from interpreting the backquote construct, you "quote" the here-document by
ferret <<'STOP'. . .STOP
Ryo--------------------To see what's going on, run this kind of test shell script
echo date
echo `date`
echo "abc `date` def"
echo 'abc `date` def'
cat <<EOFdate`date`EOF
cat <<'EOF'date`date`EOF
