[GEMPAK #YSZ-359359]: Gempak(GDCNTR) running via command line but not from shell script.

Hello Kaviyazhahu,

The script is not running correctly because of the last part

> r
> e
> EOF


What this does within GDCNTR is "run" the script, but "exit" instead of 
confirmation.  From the command line you've noticed the "Enter <cr> to accept 
parameters or type EXIT" prompt.  If you run (r) and then exit (e), that exit 
command is being entered for this prompt.

The solution is to have an empty line in your script, which acts as an "enter" 
command for that prompt:

gdcntr <<EOF
GDFILE = ecmwfwind24.grd 
GDATTIM = 130724/0000F000
GFUNC = SQRT(ADD(MUL(UWND,UWND),MUL(VWND,VWND)))
GVCORD = none
GLEVEL = 0 
CTYPE = F 
fline = 0;1;2;3;4;5;6;7;8;9;10;11;12;13;14;15;16;17;18;19;20;21;22;23;24;25
fint = 0;1;2;3;4;5;6;7;8;9;10;11;12;13;14;15;16;17;18;19;20;21;22;23;24;25
scale = 0
MAP = 32/1/2
GAREA = -60;30;30;120
CLRBAR = 1/V/cl/.2;.55
TITLE = 1/-2/ECMWF WIND SPEED-24/07/2013 00 hrs
TEXT = 1
DEVICE = XW | ECMWF WIND | .9;.9
r

e
EOF
