Bash as input to Fortran
 

Hi guys,

I have an Fortran 90 program which has two values it needs to read in from the shell.

If there was only one read, then I have found that the following script is possible in bash to automate running this f90 code many times...

input=10
echo $input | ./f90program

However, if I have two variables to feed into the f90program, I have found that trying...

echo "$input1 $input2" | ./f90program

...does not work, can anyone suggest a way to solve this minor problem?

Thanks,

Natski

Perhaps don't quote the input variables?

Or maybe your fortran code wants the two variables on seperate lines? In which case

echo -e "$input1\n$input2" | ./f90program

will work

That's perfect, thanks a lot Cantab!
