我有一个交互式FORTRAN程序,需要用户提供各种输入。现在,我想将此Fortran程序的输出存储到变量中,并在shell脚本中使用此值。我试过了
var=`./test` and var=$(./test)
但在这两种情况下,它都不会提示用户输入并保持空闲状态。我该怎么办? 一段示例fortran代码就像这样
test.f
program test
character*1 resp1, resp3
integer resp2, ans
write(*,*) 'Think of a prime number less than 10'
write(*,*) 'Say whether it is odd or even'
write(*,*) 'Write o/e'
read(*,*) resp1
if ( resp1 .EQ. 'e' ) then
ans=2
else
write(*,*) 'Is the number close to 4 or 8'
read (*,*) resp2
if ( resp2 == 8 ) then
ans=7
else
write(*,*) 'Is the number greater than or less than 4'
write(*,*) 'Write g or l'
read (*,*) resp3
if ( resp3 .EQ. 'l' ) then
ans=3
else
ans=5
end if
end if
end if
write(*,*) ans
end
Compiled as gfortran test.f -o test
然后我使用了这样的脚本
test.sh
var=`./test`
echo "The answer you are looking for is " $var
我相信我无法找到一些非常微不足道的东西。请帮我。
P.S。这只是一个示例代码和脚本,我的实际脚本和代码差别很大。

Jean-FrançoisFabre是对的。
program test
character*1 resp1, resp3
integer resp2, ans
write(0,*) 'Think of a prime number less than 10'
write(0,*) 'Say whether it is odd or even'
write(0,*) 'Write o/e'
read(5,*) resp1
if ( resp1 .EQ. 'e' ) then
ans=2
else
write(0,*) 'Is the number close to 4 or 8'
read (5,*) resp2
if ( resp2 == 8 ) then
ans=7
else
write(0,*) 'Is the number greater than or less than 4'
write(0,*) 'Write g or l'
read (5,*) resp3
if ( resp3 .EQ. 'l' ) then
ans=3
else
ans=5
end if
end if
end if
write(6,*) ans
end
问题是stderr(0),答案是stdin(5),结果是stdout(6)
var=`./test`
之后工作正常。
