处理前按字母顺序对文件排序

使用一些管道和sort

find . -type f -print0 | sort -z | xargs -r0 sha256sum > sha256SumOutput

解释

从man find

   -print0
        True; print the full file name on the standard output, followed
        by a null character (instead of the newline character that -print
        uses). This allows file names that contain newlines or other
        types of white space to be  correctly  interpreted by programs
        that process the find output.  This option corresponds to the -0
        option of xargs.

从man sort

   -z, --zero-terminated
        line delimiter is NUL, not newline

从man xargs

   -r
        If the standard input does not contain any nonblanks, do not run
        the command. Normally, the command is run once even if there is
        no input. This option is a GNU extension.

   -0   
        Input items are terminated by a null character instead of by
        whitespace, and the quotes and backslash are not special (every
        character is taken literally).  Disables the end of file string,
        which is treated like any  other  argument. Useful when input
        items might contain white space, quote marks, or backslashes.
        The GNU find -print0 option produces input suitable for this mode.

第一列中的值相同，因为文件在我的测试中没有任何内容。

您应该能够将您的输出从管道find传输到sort.
