Question

我们有如下的ASCII艺术

ART  _____                            
ART |  __ \               
ART | |__) |__  ___ _ __   
ART |  ___/ _ \/ _ \ '__|  
ART | |  |  __/  __/ |    
ART |_|   \___|\___|_|     
ART                        
ART

我们有一个变量$ {art} =＆＃34; 123456＆＃34;并希望用$ {art}替换ART，因此系统将打印标准输出，如此

123456  _____                            
123456 |  __ \               
123456 | |__) |__  ___ _ __   
123456 |  ___/ _ \/ _ \ '__|  
123456 | |  |  __/  __/ |    
123456 |_|   \___|\___|_|     
123456                        
123456

我试过这个，因为这篇文章建议

sed -i "s/ART/${art}/g" ascii-art

显示以下错误消息：

sed: -e expression #1, char 6: unterminated `s' command

我在Linux ip-10-22-37-149 4.4.8-20.46.amzn1.x86_64 #1 SMP Wed Apr 27 19:28:52 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux (Amazon EC2)

sed --version返回：

有什么想法？

谢谢！

如果$art包含/，您可能需要反斜杠或使用其他分隔符。

或者，使用Perl：

perl -i -pe 's/ART/$ENV{art}/g' -- file

这将在导出$art时起作用，如果不导出，只需将其导出为命令：

art=$art perl ...

sed用变量中的文本替换文本
