This is the shellis_type class for generating objects with logical
components to determine the runtime shell type of the operating system.
When an object of this type is generated, a single object component corresponding to runtime shell name is set to .true.
.
If the runtime shell name is determined to be sh
, additional attempt will be made to resolve the actual runtime shell name.
This is because sh
is frequently a symlink with an actual target (for example dash
on Ubuntu).
Additionally, the posix
component of the object is set to .true.
if the runtime shell name corresponds to,
Normally (, but not necessarily), the runtime operating system for the above shells is Unix (either macOS or variants of linux).
As of July 2022, the above shells are known to have the highest level of compliance with the POSIX standard.
Alternatively, the windows
component of the object is set to .true.
if the runtime shell corresponds to,
As of July 2022, the above shells are exclusively available on Windows operating systems.
As of July 2022, shells that adhere to neither Windows nor POSIX conventions are the following,
[out] | failed | : The output scalar logical of default kind LK that is .true. if and only if an error occurs while inferring the system shell name.(optional. If missing and a runtime error occurs, the program will halt by calling error stop .) |
[in,out] | errmsg | : The input/output scalar character of default kind SK of arbitrary length type parameter.If an error occurs, errmsg will be set to a descriptive message about the nature of the runtime error.A length of LEN_IOMSG characters is likely sufficient to capture most error messages in full. (optional. It can be present only if failed is also present. If missing, no error message will be output.) |
shell
: The output scalar object of type shellis_type containing the specifics of the runtime system shell.

sh
) is a programming language described by the POSIX standard.sh
is a specification, not an implementation, /bin/sh
is a symlink (or a hard link) to an actual implementation on most POSIX systems.sh = .true.
implies that the runtime shell most likely points to a POSIX-compliant shell. To find out the target of sh
, use the command file -h /bin/sh
