Question

从文档中，:global命令的语法为：

:[range]g[lobal]/{pattern}/[cmd]
                        Execute the Ex command [cmd] (default ":p") on the
                        lines within [range] where {pattern} matches.

我也遇到过:g的用法：

:g/apples/+1,/peaches/ s/^/# /g
:g/start/+1,$ sort n

这里的/apples/+1,/peaches/属于{pattern}吗？该语法在哪里记录？

我刚刚在Vim Tips Wiki中找到了:global用法的解释：

:g/apples/,/peaches/ s/^/# /g
    Insert "# " at the start of each line in all identified blocks. 
    :g/apples/ identifies each line containing "apples". 
    In each such line, .,/peaches/ s/^/# /g is executed 
    (the . is assumed; it means the current line, where "apples" occurs).

因此,/peaches/在这里定义了替代命令的范围。有点令人困惑的部分（我在文档中没有提到）是初始'.'在范围内是可选的。添加它会使命令更加明显：

:g/apples/.,/peaches/s/^/# /g

Vim的全局命令（带有逗号连接的模式）
