我正在处理我自己的个人任务，帮助我提取以"inet address "开头的ip地址。从"ip地址"命令。我还想提取与每个ip地址相关联的接口。
例如:
接口名称| IP地址Eth0 | 192.168.2.100/24Eth1 | 10.10.2.100/20
下面是我正在处理的输出:
eth0 Link encap:Ethernet HWaddr b8:ac:6f:65:31:e5 inetaddr:192.168.2.100 Bcast:192.168.2.255掩码:255.255.255.0 inet6 addr:fe80::baac:6fff:fe65:31e5/64 Scope:Link UP BROADCAST RUNNING MULTICASTMTU:1500 Metric:1 RX packets:2697529 errors:0 dropped:0 overruns:0frame:0 TX packets:2630541 errors:0 dropped:0 overruns:0 carrier:0txqueuelen:1000 RX bytes:2159382827 (2.0 GiB) TX(1.2 GiB) Interrupt:17

下面是我做过的代码:
import re
with open('rawdata.txt', 'r') as file:
data = file.read()
s = []
subnetM = re.findall(r'(?<=Mask:255.)(.*)', data)
position = 0
for i in subnetM:
if i == "255.255.0":
s.insert(position, "/24")
if i == "255.255.255":
s.insert(position, "/32")
if i == "0.0.0":
s.insert(position, "/8")
position = position + 1
c = []
for paragraph in data.split('nn'):
ma = re.compile("^(S+).*?inet addr:(S+)", re.MULTILINE | re.DOTALL)
result = ma.match(paragraph)
if result != None:
result = ma.match(paragraph)
interface = result.group(1)
ip = result.group(2)
c.append([interface, ip])
print("Interface name | IP address")
for (interface, ip) in c:
print(interface, ' | ', ip)
虽然这工作得很好，我似乎无法提取子网掩码前缀，如/24，/25，/26与ip地址。
下面是我得到的输出:输出
我发布了一个完整的工作程序来展示JSON输出的优势:
import json
import subprocess
with subprocess.Popen("/usr/sbin/ip --json address".split(), stdout=subprocess.PIPE) as proc:
ip = json.load(proc.stdout)
for iface in ip:
name = iface['ifname']
for info in iface['addr_info']:
print(f"{name} | {info['local']}/{info['prefixlen']}")
