All tables that reside in the group are redistributed if the command succeeds and returns sqlcode 0.
如果命令成功,并返回sqlcode 0,则组中所有的表都被重分发。
For example, if the command-line argument were +helpverbose, str would be +helpverbose, and len would be 12.
例如,如果命令行参数为 +helpverbose,则 str 为 +helpverbose,len 为 12。
As you learned previously, if the command returns a zero, then it was successful; if it returns a non-zero, then it failed.
如前所述,如果该命令返回零,那么该命令的执行是成功的;如果它返回的是非零,那么它的执行是失败的。
And here's a little trick -- and again, we promised to point -- out little tricks of the trade -- if I know I want to execute the last command I typed that started with an m, bangm will actually figure out what that command was and redo it for me so I don't have to figure it out, or you can go back in time in a terminal window.
这里有个小技巧--此外,我们许诺指出行业中的,一些小技巧-,如果我知道我想执行我写入的上一个命令,是以m开头的,!m会明白那个命令是什么,然后为我恢复上次操作,所以我不需要明白它,或者你可以回到,那个终端窗口。
