对于模式猛砸搜索文件，替换图案code，包括Git的分行名称

问题描述

我有一个README.md文件，其中我想带线$来代替文字标识 {{codeSHIP_ code}} C $ C - 专门构建状态图像code片段，包括git的分支名

I have a README.md file where I'd like to replace a text identifier {{CODESHIP_CODE}} with a line of code – specifically a build status image code snippet that includes the git branch name.

我想它会是这个样子......

I'm thinking it would look something like this...

1. 将当前分支 git的REV-解析--abbrev-REF HEAD 在bash变量


2. 将模式/字符串变量来搜索。这种模式/字符串只是用来作为标识快速找到其中的README.md文件我想我的输出构建状态图像code。


3. 使用 SED （可能是的grep ）来搜索指定的 {{codeSHIP_ code}} 模式/串并构建图像状态code替换

1. Place the current branch git rev-parse --abbrev-ref HEAD in bash variable
2. Place the pattern/string to search for in a variable. This pattern/string is just used as an identifier to quickly locate where in the README.md file I want to output my build status image code.
3. Use sed (possibly grep) to search the README.md file for the specified {{CODESHIP_CODE}} pattern/string and replace it with the build image status code

在code我写的是这样的：

The code I wrote looks like this:

#!/bin/bash

# Get the current branch
function git_branch {
    git rev-parse --abbrev-ref HEAD
}

# Set variable to current branch
branch=$(git_branch)

# Define the pattern to search for
# This pattern/string gets replaced with the build status image code
id="{{CODESHIP_CODE}}"

# Create build status image code
# Inject the $branch variable into the correct location
codeship_build_status="[ ![Codeship Status for ExampleGitHubUser/ExampleRepo](https://codeship.com/projects/a99d9999-9b9f-9999-99aa-999a9a9a9999/status?branch=$branch)](https://codeship.com/projects/999999)"

# Find the pattern to replace
# Then replace it with the build status image
sed -i -e "s/{{CODESHIP_CODE}}/$codeship_build_status/g" README.md

问题是，我不断收到以下错误：

The problem is that I keep getting the following error:

SED：1：S / {{codeSHIP_ code}} / [...！：坏标志替换命令：'A'

我不知道如何解决这个问题，使脚本正常工作。任何帮助将大大AP preciated。

I'm not sure how to resolve this issue, so that the script works correctly. Any help would be greatly appreciated.

推荐答案

您不能使用包含转义符替换字符串。逃离字符串中的分隔符，或者切换到不同的。

You can't use a replacement string that contains the unescaped delimiter. Escape the delimiters in the string, or switch to different ones.

${codeship_build_status////\\/} # escape
# or
s%{{CODESHIP_CODE}}%$codeship_build_status%g #

确认新的分隔符不包含在字符串中

Make sure the new delimiter isn't contained in the string.
