想获取指定 [programxx] 区间下的n行 内容，想要的效果 如果获取open-falcon_agent得到：

directory = /usr/local/open-falcon_agent
command = /usr/local/open-falcon_agent/falcon-agent -c cfg.json
autostart=true
autorestart=true
startsecs=3
user = root
redirect_stderr = true
stdout_logfile = /usr/local/open-falcon_agent/var/app.log

moperyblue

1. sed 't;/program:open-falcon_agent]/{:a;N;/\n\s*$/!ba;s//&/;D};d'
   
2. sed -r '/program:open-falcon_agent]/{:a;N;/\n\s*$/!ba;s/[^\n]+\n//;q};d'

2. sed -n '/\[program:open-falcon_agent\]/{h;:1;n;/^\s*$/!{H;b1};g;p;q}' i
   
3. [program:open-falcon_agent]
   
4. directory = /usr/local/open-falcon_agent
   
5. command = /usr/local/open-falcon_agent/falcon-agent -c cfg.json
   
6. autostart=true
   
7. autorestart=true
   
8. startsecs=3
   
9. user = root
   
10. redirect_stderr = true
    
11. stdout_logfile = /usr/local/open-falcon_agent/var/app.log
