imjust分配变量大气压，得到了数W / O逗号结果
我得到这个错误语法类型：

imjust assigning variables atm, getting the number w/o commas
i get this syntax type of error:

awk: 9: unexpected character '`'
awk: 10: unexpected character '`'
awk: 11: unexpected character '`'
(standard_in) 2: syntax error
(standard_in) 2: syntax error

推荐答案

也许这将帮助你清理你的语法一点，所以我们能理解你想要做的事。

Maybe this will help you clean up your syntax a little so we can understand what you're trying to do.

BEGIN和END块是可选的。忽略模式的时刻，一个awk程序可能是这样的。

BEGIN and END blocks are optional. Ignoring patterns for the moment, an awk program might look like this.

BEGIN {
    # Things to be done before you start processing rows.
}
{
    # Things to be done for each row.
}
END {
    # Things to be done after processing the last row.
}

如果你不碰巧需要开始或终止块，它可能看起来更像这一点。

If you don't happen to need BEGIN or END blocks, it might look more like this.

{
    # Things to be done for each row.
}

这awk程序指定的$ 2，$ 3和$ 4变量达泰值，一旦它打印的每一行。

This awk program assigns the value of $2, $3, and $4 to the variable dataI, and prints it once for each row.

{
  dataI = sprintf("%s %s %s", $2, $3, $4);
  print dataI;
}

这是分配有$ 2，$ 3和$ 4中的值没有任何影响。

That assignment has no effect on the values of $2, $3, and $4.
