无法使用uniq -c来计算重复的行数

我无法使用uniq来计算重复行的数量。

输出以执行uniq on

[root@cpod-compute-1 ~]# for i in $(awk -F= '/PCI_SLOT_NAME/{print $2}' /sys/class/net/*/device/uevent); do lspci -Dm | grep $i; done
0000:01:00.0 "Ethernet controller" "Intel Corporation" "I350 Gigabit Network Connection" -r01 "Cisco Systems Inc" "Device 00d5"
0000:01:00.1 "Ethernet controller" "Intel Corporation" "I350 Gigabit Network Connection" -r01 "Cisco Systems Inc" "Device 00d5"
0000:09:00.0 "Ethernet controller" "Cisco Systems Inc" "VIC Ethernet NIC" -ra2 "Cisco Systems Inc" "VIC 1227 PCIe Ethernet NIC"
0000:0a:00.0 "Ethernet controller" "Cisco Systems Inc" "VIC Ethernet NIC" -ra2 "Cisco Systems Inc" "VIC 1227 PCIe Ethernet NIC"

预期输出

2  "Ethernet controller" "Intel Corporation" "I350 Gigabit Network Connection" -r01 "Cisco Systems Inc" "Device 00d5"
2  "Ethernet controller" "Cisco Systems Inc" "VIC Ethernet NIC" -ra2 "Cisco Systems Inc" "VIC 1227 PCIe Ethernet NIC"

我无法理解似乎重复的相邻行之间的区别。

请让我知道是否需要其他输出。

谢谢。

EDIT1：由于在这种情况下OP更改了问题以获取重复的行值，因此请尝试以下操作。

for i in $(awk -F= '/PCI_SLOT_NAME/{print $2}' /sys/class/net/*/device/uevent)
do
   lspci -Dm | grep $i |\
   awk '{$1="";sub(/^ +/,"");count[$0]++} END{for(c in count){if(count[c]>1){print count[c], c}}'
done

您能不能尝试以下操作，尚未经过测试（以获取唯一值）。由于您开始专注于行中即将出现的空间，因此我尝试解决该问题。现在，为什么要空出输出，因为您要取消$1。因此，我在这里要做的是在处理数组计数逻辑之前用NULL替换初始空间。

for i in $(awk -F= '/PCI_SLOT_NAME/{print $2}' /sys/class/net/*/device/uevent)
do
   lspci -Dm | grep $i |\
   awk '{$1="";sub(/^ +/,"");count[$0]++} END{for(c in count){if(count[c]==1){print count[c], c}}'
done

OP正在做的是，获取所有元素的数量；为了获得唯一元素计数，我们应该将所有元素中的if(count[c]==1放在代码的END块中。同样，我假设您要使数组的任何特定字段的索引都为当前行（$ 0），然后将count[$0]++更改为其中的特定字段号。
