请问uniq命令对文件的大小有限制吗。当文件超过某一限定行数时，结果是不是就不准确了。我在处理一个超过4万行的文件时。很多重复项都显示异常：
[root@localhost ~]#
[root@localhost ~]# sort RAB\ Failures.csv | cut -d "," -f 4 | wc -l
47388
[root@localhost ~]# sort RAB\ Failures.csv | cut -d "," -f 4 | grep FAILED | wc -l
24522
[root@localhost ~]# sort RAB\ Failures.csv | cut -d "," -f 4 | uniq -c -d
2 HOST CAUSE HANDOVER FAILED
2 MCP CAUSE ESTABLISH TMO
2 HOST CAUSE HANDOVER FAILED
4 MCP CAUSE ESTABLISH TMO
3 HOST CAUSE HANDOVER FAILED
