regex - 使用sed替换字符之间的特定单词？

Question

有谁知道如何替换()之间的特定单词.因此，例如，替换单词 and与 or在两组括号之间:

(grade='C' and grade='D' and grade='E') and (int_rate>=10 and int_rate<=20) and pub_rec>=0 and term=' 36 months'

这将是:

(grade='C' or grade='D' or grade='E') and (int_rate>=10 or int_rate<=20) and pub_rec>=0 and term=' 36 months'

Answer 1

非常愚蠢的方法:

$ sed 's/and/or/g' INPUT | sed 's/) or (/) and (/' | sed 's/\(.*\)or/\1and/'
(grade='C' or grade='D' or grade='E') and (int_rate>=10 or int_rate<=20) and pub_rec>=0 
and term=' 36 months'
