linux - 计算出现次数分组依据

Question

我需要计算每次出现的次数，而不仅仅是我用 sort 制作的“group by”:

>>> cat /var/log/squid/access.log* | awk '{ print $NF }' | sort -u
TCP_CLIENT_REFRESH_MISS:DIRECT
TCP_DENIED:NONE
TCP_HIT:NONE
TCP_IMS_HIT:NONE
TCP_MEM_HIT:DIRECT
TCP_MEM_HIT:NONE
TCP_MISS:DIRECT
TCP_MISS:NONE
TCP_NEGATIVE_HIT:NONE
TCP_REFRESH_HIT:DIRECT
TCP_REFRESH_MISS:DIRECT
>>>

你会怎么做？

Answer 1

sort | uniq -c正是您要找的。
