关于awk：无法使用uniq -c打印所有行的计数

Unable to use uniq -c to print counts for all lines

我想使用uniq来计算每行的出现次数，但不包括行首的数值(例如：0000：01：00.0)

每次发生不止一次。在某些情况下，每次出现只会发生一次。

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。

相关讨论

OP使用的代码为：

1
2
3

for i in $(awk -F= '/PCI_SLOT_NAME/{print $2}' /sys/class/net/*/device/uevent); do
lspci -Dm | grep $i | awk '{$1="";print $0}' | sort | uniq -c;
done

它应该读为：

1
2
3

for i in $(awk -F= '/PCI_SLOT_NAME/{print $2}' /sys/class/net/*/device/uevent); do
lspci -Dm | grep $i | awk '{$1="";print $0}'
done | sort | uniq -c;

这两种情况之间的区别在于，在第一种情况下，您对单个命令的输出进行了排序：

1	lspci -Dm \| grep $i \| awk '{$1="";print $0}'

在第二种情况下，对完整的for循环的输出进行排序。

更新后的版本如下：

1
2
3
4

awk -F= '(FNR==1){ OFS=FS=(f==0 ?"=" :""); $0=$0 }
(f==0) && /PCI_SLOT_NAME/{a[$2];next}
($1 in a) {$1=""; $0=$0; $1=$1; 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：

1
2
3
4
5

awk -F= '(FNR==1){ OFS=FS=(f==0 ?"=" :""); $0=$0 }
(f==0) && /PCI_SLOT_NAME/{a[$2];next}
($1 in a) {$1=""; $0=$0; $1=$1; b[$0]++}
END{for (i in b) print b[i],i}
' /sys/class/net/*/device/uevent f=1 <(lspci -Dm)
