Shell Programming and Scripting

Dear Freinds,

Help needed in input redirection .
My problem is as follows..
I have a shell script as follows which calls another gnuplot script .

datagen.sh

Code:

#!/bin/ksh

gnuplot plot_I.plt

In the above file I am calling another file called plot_I.plt which reside in the same directory
Now my problem is I dont want to call that file instead of I want to merge that file plot_I.plt to datagen.sh and delete that file plot_I.plt

plot_I.plt

Code:

#!/usr/local/bin/gnuplot -persist

reset
set xrange[0:10400]
set x2range[0:2600]
plot "I_indat.txt" ax x2y1 with lines, "I_outplot" with lines
pause -1

Code:

I know there is command in unix to input a file like
command << EOF
EOF . But never used it . Please help how to input redirection using the above command or anything beside this..

I tried something like this but wont get sucess..

Code:

 gnuplot <<EOF
#!/usr/local/bin/gnuplot -persist
reset
set xrange[0:10400]
set x2range[0:2600]
plot "I_indat.txt" ax x2y1 with lines, "I_outplot" with lines
pause -1
EOF`

I am sure I am wrong with my code , please help ..
Thanks in advance..

Next time post your code in [ CODE ] [ /CODE ] blocks.

But using my intuition I can guess that your EOF has spaces to the left of it. It should immediately follow the line feed.

Not like this

Code:

      cat ... <<EOF
        blah
        EOF

but like this

Code:

      cat ... <<EOF
blah
EOF

Sorry for that..As much as possible I am trying my best to explain.

Now I am doing like below
First method:

Code:

  echo "#!/usr/local/bin/gnuplot " > plot_I.plt
  echo "reset" >> plot_I.plt
  echo "pause -1" >> plot_I.plt

  gnuplot plot_I.plt  #calling the file plot_I.plt

Its working fine.

Please help me do the same with <<EOF



Yes I did that..

Code:

gnuplot <<EOF
#!/usr/local/bin/gnuplot -persist 
reset 
pause -1 
EOF

But One problem when I do the same with a temporary file, I mean with the 1st method the plot remains there until I press quit. But in this case ie, <<EOF case it comes for a fraction of second then vanish automatically..


Thank you..

Yes you do, look for your code like

Code:

   pause -1
  EOF`

That looks like two spaces to me.

Yeah You may be right Mr. Porter.. But My guess was
<<....EOF to the left of EOF . Thats why I said I have no spaces left to EOF.
