用sed替换文本 [英] Replace text using sed

问题描述

我收到上次修改日期如下：

  olddate =`grep -m1内置script.sh cut -c 22-29` 
  

我得到当前日期：

  newdate =`date +％d /％m /％y` 
  

基本上我想用新的日期替换旧的日期

  sed -i s / $ olddate / $ newdate / gscript.sh 
  

但这不起作用日期包含斜杠。我周围环顾四周，找不到正确逃脱的方式。任何帮助将不胜感激。

解决方案

您可以使用除斜杠之外的分隔符，例如;

  sed -i; $ olddate; $ newdate; gscript.sh 
  




i am having trouble replacing the modified date in my script via sed.

I am getting the last modified date like this:

olddate=`grep -m1 "Built " script.sh | cut -c 22-29`

I get the current date with:

newdate=`date +%d/%m/%y`

Basically i want to replace old date with new date

sed -i "" "s/$olddate/$newdate/g" script.sh

But this doesn't work as the date contains slashes. I've looked around and i can't find the way to escape them properly. Any help would be appreciated.

解决方案

You can use separators other than slashes, for instance ";"

sed -i "" "s;$olddate;$newdate;g" script.sh
