This should work: 这应该工作：
sed 's#/Volumes/\([^/]*\)/.*#\1#'
Instead of using / to mark the search and replace expressions, you could use any other character as well. 您可以使用任何其他字符，而不是使用/来标记搜索和替换表达式。 # is a commonly used character if your search or replace expressions contain the character / in them. 如果搜索或替换表达式中包含字符/ ，则#是常用字符。
$ sed 's#/Volumes/\([^/]*\)/.*#\1#' <<< "/Volumes/Macintosh HD/Users/test/"
Macintosh HD
