请问怎么删除某行的几个字符

feigepp

我的文件大概是这样的：


TIMESTAMP(0)
TIMESTAMP(9) WITH TIME ZONE


我想输出成

TIMESTAMP
TIMESTAMP WITH TIME ZONE


就是把括号里的内容连同括号一起删掉

有办法吗

The syntax of the s (as in substitute) command is ‘s/regexp/replacement/flags’. The / characters may be uniformly replaced by any other single character within any given s command. The / character (or whatever other character is used in its stead) can appear in the regexp or replacement only if it is preceded by a \ character.
