使用sed在linux中的多个文件中查找和替换字符串（正则表达式）

I have a list of files with strings like {{abc-exfs-value}}. The sub string abc differs in each of the file. For example, a regex search (java) like: \{\{*-exfs-value\}\} will return all the strings that is of concern here. How to proceed on replacing all those strings that match the regex pattern in files in linux?

我有一个包含{{abc-exfs-value}}等字符串的文件列表。子串abc在每个文件中都不同。例如,正则表达式搜索(java)如:\ {\ {* - exfs-value \} \}将返回此处关注的所有字符串。如何在linux中的文件中替换所有匹配正则表达式模式的字符串?

I am able to get the list of files using grep -R '\-exfs\-value' .. Using sed how to replace the strings?
