Simple script with here document. Can't figure out what's wrong.

Hi everyone,
I am having trouble with this pretty simple script that uses here document as an input to the plotting program gnuplot.

Code:

#!/bin/sh
for i in file1 file2 file3
do
        gnuplot<<+
        set multiplot
        set xrange [0:10]
        set xrange [0:1]
        plot $i u 3:5 w linespoints
        +
done

The error that I am getting is

Code:

./plot.sh: line 11: syntax error: unexpected end of file

Can someone point me out to what is wrong here? Thanks.

Hi,

The end token of the here document (+ in your case). should be placed against the left border (no indentation).

Hope this helps.

Move your "+" flush left.

For better readability, you might also consider renaming it from "+" to "!" or "EOF".

Thank you guys very much. The book where I learned about here document doesn't really mention that.
