把/users/2251663/moments这段放到前一行末尾去
比如我要得到这样的结果Completed 200 OK in 13ms (Views: 6.5ms | ActiveRecord: 2.5ms) /users/2251663/moments

谢谢了～

  1. awk '{printf(NR%2 != 0)?$0" ":$3"\n"}END{print ""}'

3楼的就行了，画蛇添足另一个方案：
  1. [seesea@UC ~]$ cat file | sed ':a; $!{N; ba}; ${s/\nStarted GET "/ /g; s/" for[^\n]*//g}'   
  2. Completed 200 OK in 13ms (Views: 6.5ms | ActiveRecord: 2.5ms) /users/2251663/moments
  3. Completed 200 OK in 2318ms (Views: 222.9ms | ActiveRecord: 1999.6ms) /cluster/2865765/brief
  4. Completed 200 OK in 5ms (Views: 1.9ms | ActiveRecord: 1.4ms) /photo/2865765/brief
  5. Completed 200 OK in 8ms (Views: 3.1ms | ActiveRecord: 1.6ms)
