Summary0001266: sh -s with operands
DescriptionWhen the -i option is not present, the standard currently says that the shell is only interactive when there are no operands and stdin and stderr are a terminal.
However when the -s option is given commands are read from stdin even when operands are present and existing shells do treat -s with operands as interactive when stdin and stderr refer to a terminal.
Desired ActionOn page 3226 lines 108308-108309 section sh, change:
If the −i option is present, or if there are no operands and the shell’s standard input and
standard error are attached to a terminal, the shell is considered to be interactive.
to
If the −i option is present, or if the shell reads commands from the standard input and the shell’s standard input and
standard error are attached to a terminal, the shell is considered to be interactive.

Interpretation response
------------------------
The standard clearly states that sh -s arg... is not interactive, and conforming implementations must conform to this. However, concerns have been raised about this which are
being referred to the sponsor.

Rationale:
-------------
All known shells, except yash, make the shell interactive in this case when standard input and standard error are connected to a terminal and we believe this historic behavior is correct.

Notes to the Editor (not part of this interpretation):
-------------------------------------------------------
Make the changes suggested in the Desired Action.
