过滤语句在IOS/XR的平台上非常有用，特别是在输出大量信息的情况下。在此总结一部分常用的过滤方式：
1.RP/0/RP1/CPU0:ios#admin show controllers fabric link port s2tx | i 3/SM5/1 | i UP….DOWN
>>>用“.”替代空格
F1/SM10/SP/0/8 UP DOWN do 3/SM5/SP/3/27 F1/SM10/3 3/SM5/1 F1/SM10/SP/0/9 UP DOWN do 3/SM5/SP/2/27 F1/SM10/3 3/SM5/1 F1/SM10/SP/0/26 UP DOWN do 3/SM5/SP/1/27 F1/SM10/3 3/SM5/1 F1/SM10/SP/0/43 UP DOWN do 3/SM5/SP/2/11 F1/SM10/3 3/SM5/1 F1/SM10/SP/1/9 UP DOWN do 3/SM5/SP/2/0 F1/SM10/3 3/SM5/1
2.RP/0/RP1/CPU0:ios#admin show controllers fabric link port s2tx | i 3/SM5/1 | i UP DOWN
>>>XR下，根据第一个条件过滤第一次，得出的结果后又用第二个条件过滤，这样非常灵活，这是“与”的关系
F1/SM10/SP/0/8 UP DOWN do 3/SM5/SP/3/27 F1/SM10/3 3/SM5/1 F1/SM10/SP/0/9 UP DOWN do 3/SM5/SP/2/27 F1/SM10/3 3/SM5/1 F1/SM10/SP/0/26 UP DOWN do 3/SM5/SP/1/27 F1/SM10/3 3/SM5/1 F1/SM10/SP/0/43 UP DOWN do 3/SM5/SP/2/11 F1/SM10/3 3/SM5/1 F1/SM10/SP/1/9 UP DOWN do 3/SM5/SP/2/0 F1/SM10/3 3/SM5/1
3.RP/0/RP1/CPU0:ios#admin show controllers fabric link port s2tx | i 3/SM5/1 | i UP.*DOWN
>>>这里面”*”表示无限次，直到碰到下一个关键字DOWN
F1/SM10/SP/0/8 UP DOWN do 3/SM5/SP/3/27 F1/SM10/3 3/SM5/1 F1/SM10/SP/0/9 UP DOWN do 3/SM5/SP/2/27 F1/SM10/3 3/SM5/1 F1/SM10/SP/0/26 UP DOWN do 3/SM5/SP/1/27 F1/SM10/3 3/SM5/1 F1/SM10/SP/0/43 UP DOWN do 3/SM5/SP/2/11 F1/SM10/3 3/SM5/1 F1/SM10/SP/1/9 UP DOWN do 3/SM5/SP/2/0 F1/SM10/3 3/SM5/1
4.RP/0/RSP1/CPU0:A9K-2#sh interfaces | i “line|MTU|input error”
>>>通过这种方式实现跟IOS一样的需求，“或”的关系
Loopback0 is up, line protocol is up MTU 1500 bytes, BW 0 Kbit Null0 is up, line protocol is up MTU 1500 bytes, BW 0 Kbit MgmtEth0/RSP0/CPU0/0 is up, line protocol is up MTU 1514 bytes, BW 100000 Kbit (Max: 100000 Kbit) 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
5.7609s#sh int | i line|\MTU|\Input queue
>>>在IOS上，如果想选好几个条件，用“\xxx”，“或”的关系
TenGigabitEthernet4/1 is up, line protocol is up (connected) MTU 1500 bytes, BW 10000000 Kbit/sec, DLY 10 usec, Input queue: 0/2000/0/0 (size/max/drops/flushes); Total output drops: 0 TenGigabitEthernet4/2 is administratively down, line protocol is down MTU 1500 bytes, BW 10000000 Kbit/sec, DLY 10 usec, Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
6. 对于XR的可以调用utility-更高级的过滤语句，如：
RP/0/RP1/CPU0:ios#admin show inter | utility ? cut Cut out selected fields of each line of a file egrep Extended regular expression grep fgrep Fixed string expression grep head Show set of lines/characters from the top of a file less Fixed string pattern matching sort Sort, merge, or sequence-check text files tail Copy the last part of files uniq Report or filter out repeated lines in a file wc Counting lines/words/characters of a file xargs Construct argument list(s) and invoke a program
如：
#show process pidin | utility egrep -e "[0-9]+r " count 1025本文出自 Frank's Blog
