经常碰到想查找多行匹配的时候，比如：有一份log如下：

想实现git log --author zhengkl的功能：

vim脚本：func! MyFindEndLine(linenr)let l:buf_end_line = line('$')let l:line = a:linenrwhile l:line <= l:buf_end_linelet l:line += 1let l:line_buf = getline(l:line)if matchstr(l:line_buf, "^commit") != ""return (l:line - 1)enendwreturn l:buf_end_lineendffunc! MyFindTextBlockFunc(string)let g:mylist = []exec "g /".a:string."/call add(g:mylist, line('.'))"let l:text = []for i in g:mylistlet l:end_line = MyFindEndLine(i)call extend(l:text,  getline(i - 1, l:end_line))call writefile(l:text, "test.txt")endfoendf:call MyFindTextBlockFunc("zhengkl")

awk脚本：#!/bin/awk -f {is_end_file = 1if (match($0, "commit")) {a = $0do {is_end_file = !getlineif (match($0, "zhengkl")) {print aprint $0is_end_file = !getlinewhile (! match($0, "commit")) {print $0is_end_file = getlinea = $0}} else {is_end_file = !getlinea =$0}} while(is_end_file != 1);}}

sed脚本：/^commit/ {: get_commithn/zhengkl/ {Hxp: readagainn/^commit/ {b get_commit}pb readagain}}

当然最方便的还是vim命令：

g/zhengkl/-1;,/commit/-1 write >> test.txt
