为什么“在命令后添加字符"显示的sed命令行显示错误?

本文介绍了为什么“在命令后添加字符"显示的sed命令行显示错误?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我已经给出了如下所示的命令行，

I have given the command line as shown below,

命令:

sed '/dump 0 $2 $3 $4 $5/dump 1 $2 $3 $4 $5/g' base_file.properties

显示错误

sed:-e表达式#1，字符22:命令后的多余字符

sed: -e expression #1, char 22: extra characters after command

同时将"s"选项设置为

while putting "s" option as

sed 's/dump 0 $2 $3 $4 $5/dump 1 $2 $3 $4 $5/g' base_file.properties

错误显示为

sed:-e表达式#1，字符32:`s'的未知选项

sed: -e expression #1, char 32: unknown option to `s'

推荐答案

似乎某些变量正在扩展为包含/的值.使用一个不包含在任何变量中的分隔符，例如

It appears that some of the variables are expanding to values that contain a /. Use a different delimiter that isn't contained in any of the variables, e.g.

sed 's@dump 0 $2 $3 $4 $5@dump 1 $2 $3 $4 $5@g' base_file.properties

(您的第一个命令不是有效的sed表达式.)

(Your first command isn't a valid sed expression.)
