无法使用 uniq -c 打印所有行的计数

Question

我想用uniq统计每一行出现的次数，不包括行首的数值（例子：0000:01:00.0）

每次出现不止一次。可能会出现每次只出现一次的情况。

示例输入

[root@cpod-compute-1 ~]# for i in $(awk -F= '/PCI_SLOT_NAME/{print }' /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"
0000:0a:00.1 "Ethernet controller" "Intel Corporation" "Ethernet Controller X710 for 10GbE SFP+" -r01 "Cisco Systems Inc" "Ethernet Converged NIC X710-DA"
0000:0a:00.2 "Ethernet controller" "Intel Corporation" "Ethernet Controller X710 for 10GbE SFP+" -r01 "Cisco Systems Inc" "Ethernet Converged NIC X710-DA"
0000:0a:00.3 "Ethernet controller" "Intel Corporation" "Ethernet Controller X710 for 10GbE SFP+" -r01 "Cisco Systems Inc" "Ethernet Converged NIC X710-DA"

预期输出

2  "Ethernet controller" "Intel Corporation" "I350 Gigabit Network Connection" -r01 "Cisco Systems Inc" "Device 00d5"
3  "Ethernet controller" "Intel Corporation" "Ethernet Controller X710 for 10GbE SFP+" -r01 "Cisco Systems Inc" "Ethernet Converged NIC X710-DA"

非工作案例示例

[root@cpod-compute-1 ~]#  for i in $(awk -F= '/PCI_SLOT_NAME/{print }' /sys/class/net/*/device/uevent); do lspci -Dm | grep $i | awk '{="";print [=12=]}' | sort | uniq -c; done
      1  "Ethernet controller" "Intel Corporation" "I350 Gigabit Network Connection" -r01 "Cisco Systems Inc" "Device 00d5"
      1  "Ethernet controller" "Intel Corporation" "I350 Gigabit Network Connection" -r01 "Cisco Systems Inc" "Device 00d5" 
      1  "Ethernet controller" "Intel Corporation" "Ethernet Controller X710 for 10GbE SFP+" -r01 "Cisco Systems Inc" "Ethernet Converged NIC X710-DA"
      1  "Ethernet controller" "Intel Corporation" "Ethernet Controller X710 for 10GbE SFP+" -r01 "Cisco Systems Inc" "Ethernet Converged NIC X710-DA"
      1  "Ethernet controller" "Intel Corporation" "Ethernet Controller X710 for 10GbE SFP+" -r01 "Cisco Systems Inc" "Ethernet Converged NIC X710-DA"

我无法理解看起来重复的相邻行有什么区别。

如果需要任何进一步的输出，请告诉我。

谢谢。

Answer 1

OP 使用的代码是：

for i in $(awk -F= '/PCI_SLOT_NAME/{print }' /sys/class/net/*/device/uevent); do 
   lspci -Dm | grep $i | awk '{="";print [=10=]}' | sort | uniq -c;
done

虽然它应该是：

for i in $(awk -F= '/PCI_SLOT_NAME/{print }' /sys/class/net/*/device/uevent); do 
   lspci -Dm | grep $i | awk '{="";print [=11=]}'
done | sort | uniq -c;

这两种情况的区别在于，在第一种情况下，您对单个命令的输出进行排序：

lspci -Dm | grep $i | awk '{="";print [=12=]}'

在第二种情况下，您对整个 for 循环的输出进行排序。

更新版本如下：

awk -F= '(FNR==1){ OFS=FS=(f==0 ? "=" : " "); [=13=]=[=13=] }
         (f==0) && /PCI_SLOT_NAME/{a[];next}
         ( in a) {=""; [=13=]=[=13=]; =; print}
        ' /sys/class/net/*/device/uevent f=1 <(lspci -Dm) | sort | uniq -c

我们现在仍然可以在 awk 中合并计数：

awk -F= '(FNR==1){ OFS=FS=(f==0 ? "=" : " "); [=14=]=[=14=] }
         (f==0) && /PCI_SLOT_NAME/{a[];next}
         ( in a) {=""; [=14=]=[=14=]; =; b[[=14=]]++}
         END{for (i in b) print b[i],i}
        ' /sys/class/net/*/device/uevent f=1 <(lspci -Dm)

无法使用 uniq -c 打印所有行的计数
