Question

This program I use has it’s own variables to set when you run it, so I want to set those variables and then greping the output then storing it inside a variable. However, I don’t know how to go about this the correct way. The idea I have doesn’t work. The focus is on lines 7 through 14.

1  #!/usr/local/bin/bash
2  source /home/gempak/NAWIPS/Gemenviron.profile
3  FILENAME="$(date -u '+%Y%m%d')_sao.gem"
4  SFFILE="$GEMDATA/surface/$FILENAME"
5  echo -n "Enter the station ID: "
6  read -e STATION
7  OUTPUT=$(sflist << EOF
8  SFFILE = $SFFILE
9  AREA = @$STATION
10 DATTIM = all
11 SFPARM = TMPF;DWPF
12 run
13 exit
14 EOF)
15 echo $OUTPUT

But I get this:

./listweather: line 7: unexpected EOF while looking for matching `)'
./listweather: line 16: syntax error: unexpected end of file

Putting together everyone’s answers, I came across a working solution myself. This code works for me:

#!/usr/local/bin/bash
source /home/gempak/NAWIPS/Gemenviron.profile
FILENAME="$(date -u '+%Y%m%d')_sao.gem"
SFFILE="$GEMDATA/surface/$FILENAME"
echo -n "Enter the station ID: "
read -e STATION

OUTPUT=$(sflist << EOF
SFFILE = $SFFILE
AREA = @$STATION
DATTIM = ALL
SFPARM = TMPF;DWPF
run
exit
EOF
)
echo $OUTPUT | grep $STATION

Thanks everyone!
