如何从txt文件中仅删除ip

Question

我有两个文件，一个是

ips.yaml

:

-
  dedicatedip: 1.1.1.11
-
  dedicatedip: 2.2.2.2
-
  dedicatedip: ''
-
  dedicatedip: 3.3.3.3
-
  dedicatedip: 3.3.3.33

这是我的

result.txt

：

+----------+-----------------------+------------------+--------+-----------------------------+---------------+
| id       | hostname              | some other field | status | networks                    | plan          |
+----------+-----------------------+------------------+--------+-----------------------------+---------------+
| 11111111 | some-hostname         | some-value       | Active | External_Networks=1.1.1.11  | not important |
| 11111111 | some another hostname |                  | Active | External_Networks=1.1.1.111 | not important |
| 11111111 | some.fqdn.com         |                  | Active | External_Networks=1.1.1.112 | not important |
| 11111111 | fourth.hostname.com   |                  | Active | External_Networks=1.1.1.1   | not important |
| 11111111 | the-other.com         | IHaveSomething   | Active | External_Networks=2.2.2.2   | not important |
| 11111111 | not.least.com         |                  | Active | External_Networks=2.2.2.25  | not important |
| 11111111 | last.fqdn.com         | The Last Value   | Active | External_Networks=3.3.3.39  | not important |
+----------+-----------------------+------------------+--------+-----------------------------+---------------+

我想从

ips.yaml

中删除

result.txt

中存在的每个ip，这样预期的输出将是：

+----------+-----------------------+------------------+--------+-----------------------------+---------------+
| id       | hostname              | some other field | status | networks                    | plan          |
+----------+-----------------------+------------------+--------+-----------------------------+---------------+
| 11111111 | some another hostname |                  | Active | External_Networks=1.1.1.111 | not important |
| 11111111 | some.fqdn.com         |                  | Active | External_Networks=1.1.1.112 | not important |
| 11111111 | fourth.hostname.com   |                  | Active | External_Networks=1.1.1.1   | not important |
| 11111111 | not.least.com         |                  | Active | External_Networks=2.2.2.25  | not important |
| 11111111 | last.fqdn.com         | The Last Value   | Active | External_Networks=3.3.3.39  | not important |
+----------+-----------------------+------------------+--------+-----------------------------+---------------+

这是我当前的bash：

while read -r yaml_ips
do
    while read -r result_ips
    do
        if [ "$yaml_ips" == "$result_ips" ]
        then
            sed "/$yaml_ips/d" result.txt
        fi
    done < <(grep -Eo 'External_Networks=[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}' result.txt | awk -F '=' '{print $2}')
done < <(awk '/dedicatedip: [0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}/ {print $2}' ips.yaml)

这是我当前的输出：

+----------+-----------------------+------------------+--------+-----------------------------+---------------+
| id       | hostname              | some other field | status | networks                    | plan          |

+----------+-----------------------+------------------+--------+-----------------------------+---------------+
| 11111111 | some-hostname         | some-value       | Active | External_Networks=1.1.1.11  | not important |
| 11111111 | some another hostname |                  | Active | External_Networks=1.1.1.111 | not important |
| 11111111 | some.fqdn.com         |                  | Active | External_Networks=1.1.1.112 | not important |
| 11111111 | fourth.hostname.com   |                  | Active | External_Networks=1.1.1.1   | not important |
| 11111111 | last.fqdn.com         | The Last Value   | Active | External_Networks=3.3.3.39  | not important |

Answer 1

这 2 遍

awk

可以通过单个命令完成此操作：

awk -F ': ' '
FNR == NR {
   if (NF > 1 && $2 ~ /^[0-9]/)
      ip[$2]
   next
}
FNR > 3 {
   nw = $6
   sub(/^[^=]*=/, "", nw)
   if (nw in ip)
      next
}
1' ips.yaml FS='[[:blank:]]*[|][[:blank:]]*' result.txt

i+----------+-----------------------+------------------+--------+-----------------------------+---------------+
| id       | hostname              | some other field | status | networks                    | plan          |
+----------+-----------------------+------------------+--------+-----------------------------+---------------+
| 11111111 | some another hostname |                  | Active | External_Networks=1.1.1.111 | not important |
| 11111111 | some.fqdn.com         |                  | Active | External_Networks=1.1.1.112 | not important |
| 11111111 | fourth.hostname.com   |                  | Active | External_Networks=1.1.1.1   | not important |
| 11111111 | not.least.com         |                  | Active | External_Networks=2.2.2.25  | not important |
| 11111111 | last.fqdn.com         | The Last Value   | Active | External_Networks=3.3.3.39  | not important |
