如何在SED中编辑多行

我有45行代码需要SED命令。由于GNU最近发生了变化，我所有的脚本都在破坏，需要-STD = legacy＆amp; - 堕落的活节。我知道该怎么做的唯一方法是使用SED。我不是计算机程序员，SED简单易懂。

这些是我的SED命令的示例。

有没有办法在循环或SED本身中执行所有这些SED命令。如果还有另一个编辑器使我也可以尝试学习这一点。

我已经尝试过，

for X in [24,28,32,36,40,45,49,53,56,60,64,68,69,73,74,79]
    sed -i '$Xs/= /= -std=legacy -fallow-invalid-boz /g' $HOME/WRF/Downloads/NCEPlibs/macros.make.linux.gnu
done

但是我遇到了错误：

$ x in [24,28,32,36,40,45,49,53,56,56,60,64,68,68,69,73,74,79] sed -i '$ XS /= /= -STD =旧版-Fallow -Invalid -boz /g' $ home/wrf/downloads/nceplibs/macros.make.linux.gnu完成bash：语法靠近意外令牌的错误

原文

I have 45 lines of code that need a sed command. Due to the recent change in GNU all my scripts are breaking and need -std=legacy & -fallow-invalid-boz. The only way I know how to do this is with sed. I'm not a computer programmer and sed is simple and easy to understand.

These are a sample of my sed commands.

Is there a way to do all these sed commands in a loop or with sed itself. If there is another editor that makes it easier I can try to learn that too.

I have tried this

for X in [24,28,32,36,40,45,49,53,56,60,64,68,69,73,74,79]
    sed -i '$Xs/= /= -std=legacy -fallow-invalid-boz /g' $HOME/WRF/Downloads/NCEPlibs/macros.make.linux.gnu
done

But I get the error:

$ for X in [24,28,32,36,40,45,49,53,56,60,64,68,69,73,74,79] sed -i
'$Xs/= /= -std=legacy -fallow-invalid-boz /g'
$HOME/WRF/Downloads/NCEPlibs/macros.make.linux.gnu done bash: syntax
error near unexpected token sed' bash: syntax error near unexpected tokendone'

要聪明很多

y="24 28 32 36 40 45 49 53 56 60 64 68 69 73 74 79"
for X in $y; do
  sed -i "${X}s/= /= -std=legacy -fallow-invalid-boz /g" $HOME/WRF/Downloads/NCEPlibs/macros.make.linux.gnu
done

这样做的事情首先

，您忘记了 do 在中中，因此for语句甚至可以在执行之前就会失败。第二[24,28,32,36,40,45,49,53,56,56,60,64,64,68,68,69,73,74,79]无效或白色空间来声明从左到右的新值。

最后但并非最不重要的一点是，在此示例中，使用 $ x 是无效的，因为bash将其读为 $ xs/，因此使用 $ {x} 是正确的方法，当然可以使用“” 而不是使用'' SO $ {x} 实际上可以使用。

doing it like this is a lot smarter

y="24 28 32 36 40 45 49 53 56 60 64 68 69 73 74 79"
for X in $y; do
  sed -i "${X}s/= /= -std=legacy -fallow-invalid-boz /g" $HOME/WRF/Downloads/NCEPlibs/macros.make.linux.gnu
done

First of all, you forgot the do statement in for so the for statement will just fail before it can even execute.

Second of all [24,28,32,36,40,45,49,53,56,60,64,68,69,73,74,79] in not valid as for uses newlines and or white spaces to declare a new value going from left to right.

And last but not least, using $X is not valid in this example as bash reads it as $Xs/ so using ${X} is the correct way and of course using "" instead of using '' so ${X} can actually be used.
