将变量从Shell脚本传递到Fortran 90程序 [英] Passing Variables from a Shell-Script to a Fortran 90 Program

问题描述

我陷入了这个小问题.我想知道是否有可能将bash-shell脚本的变量传递给f90代码?

I'm stuck on this little problem. I was wondering if it is possible to pass a variable of a bash-shell script to a f90 code?

推荐答案

我很确定之前已经在这里进行了讨论，但是我找不到确切的重复项.

I am pretty sure it was discussed here before, but I cannot find an exact duplicate.

您可以将参数直接作为参数传递给程序

You can pass arguments directly as arguments to the program

  ./program arg1 arg2

您可以使用子例程 GET_COMMAND ARGUMENT 和 COMMAND_ARGUMENT_COUNT .单击链接以获取有用的示例.

you can retrieve the values in the program as character strings in Fortran 2003 using subroutines GET_COMMAND ARGUMENT and COMMAND_ARGUMENT_COUNT. Click on the links to get useful examples.

在较早的Fortran中，您必须使用非标准扩展名，例如子例程 GETARG 和 IARGC .

In older Fortran you have to use non-standard extensions, such as the subroutines GETARG and IARGC.

您还可以读取脚本中设置的环境变量

You can also read an environment variable which was set in the script

VAR1 = ...
VAR2 = ...
./program

使用Fortran 2003子例程 GET_ENVIRONMENT_VARIABLE .在较早的Fortran中，您必须使用一些非标准扩展名，例如子例程 GETENV .

using Fortran 2003 subroutine GET_ENVIRONMENT_VARIABLE. In older Fortran you have to use some non-standard extension, such as the subroutine GETENV.

您还可以将文件重定向到程序的标准输入，并使用 READ 语句读取数据.

You can also redirect a file to the standard input of the program and read the data using the READ statement.
