Shell Programming and Scripting

I am trying a set up a very simple korn shell script. It has 2 basic steps.

Firstly I read the first line of a text file (which is a file name)
Secondly I run a fortran executable using that line

I must be doing something wring because it wouldn't work. I know that the executable wants the file name with ' ' around it but I thought I'd done this. Here is my script

Code:

file="filenames"
while read line
do
    ./a.out <<EOF
    ${" ' " $line " ' "},
    EOF
done <"$file

I am obviously misunderstanding something here. I can get the executable run outside the loop if I give it the string, but I need it to run for each line of the file. Do I need to read the file into an array then run it?

Any help would be so great.
Thanks

I'm not sure what you're trying to do with ${" ' " $line " ' "}, You also forgot an ending quote after "$file

When you run it manually, what exactly do you type?

How about

Code:

while read line
do
        ./a.out <<EOF
${line}
EOF
done <"$file"

The line is a filename so I just type

Code:

./a.out<<EOF
'20090924_001.nc'
EOF

and it runs. The line from the file doesn't have the quotations so I need to pass them to enable to executable to run. I'm not sure how to do that.

You were trying to be tricky about it, but it's really not

Code:

while read line
do
        ./a.out <<EOF
'${line}'
EOF
done <"$file"

Thanks. Yeah I assumed it was more difficult than it actually was. I'll try to do things the easy way next time.
