Summary

0000718: sh -i -c '...' should not read its input from terminal

Description

XCU 2.3 page 2321 lines 73637-73638 says:

    The shell shall read its input in terms of lines from a file, from
    a terminal in the case of an interactive shell, or from a string
    in the case of sh −c or system().

XCU description of sh page 3190 lines 106748-106752 says:

    The standard input shall be used only if one of the following is
    true:
      * The −s option is specified.
      * The −c option is not specified and no operands are specified.
      * The script executes one or more commands that require input
        from standard input (such as a read command that does not
        redirect its input).

These two sections conflict in this case:

    sh -i -c '...'

Desired Action

Change XCU 2.3 page 2321 lines 73637-73638 from:

    The shell shall read its input in terms of lines from a file, from
    a terminal in the case of an interactive shell, or from a string
    in the case of sh −c or system().

to:

    The shell shall read its input in terms of lines. (For details
    about how the shell reads its input, see the description of the sh
    utility on page 3189.)

(0001672) eblake (manager) 2013-07-11 15:55 edited on: 2013-07-11 15:56	Make the changes suggested in the Desired Action. Additionally, at line 106766 [sh INPUT FILES], change: If the input file is empty or consists solely of blank lines or comments, or both, sh shall exit with a zero exit status. to: If the input file consists solely of zero or more blank lines and comments, sh shall exit with a zero exit status.
