我正在尝试使用sed但使用正则表达式取消注释文件内容(例如:[0-9] {1,5})

# one two 12
# three four 34
# five six 56

以下是有效的:

sed -e 's/# one two 12/one two 12/g' /file

但是,我想要的是使用正则表达式模式替换所有匹配而不输入数字但保留结果中的数字.

鉴于以下Grails域类,如何将isbn的显示字段名称重命名为"ISBN"(而不是默认的"Isbn"),并将作者重命名为"Author(s)"(与默认值相对) "作者")？

class Book {
    String name
    String isbn
    static hasMany = [ authors: Author ]
}

class Author {
    String name
}

每当我第一次运行我的Grails应用程序时,使用可搜索的0.6.4,我收到以下错误:
