方法1:匹配 inet addr 这行;以冒号为分隔符,显示第2段;再次以空格为分隔符,显示第1段
[root@localhost ~]# ifconfig eth0 |grep ‘inet addr‘ |cut -d: -f2 |cut -d" " -f1
192.168.150.53 |
方法2:匹配 inet addr 这行;以空替换从开头到 addr: 的字符串;再次以空替换从Bcast到结尾的字符串
[root@localhost ~]# ifconfig eth0 |grep ‘inet addr‘ |sed ‘s/^.*addr://g‘ |sed ‘s/Bcast.*$//g‘
192.168.150.53 |
方法3:匹配 inet addr 这行;以:或者空格作为分隔符,然后打印第4列
[root@localhost ~]# ifconfig eth0 |grep ‘inet addr‘ |awk -F[:" "]+ ‘{print $4}‘
192.168.150.53 |
方法4:匹配 inet addr 这行;以:作为分隔符,打印第2列,然后再打印第一列
[root@localhost ~]# ifconfig eth0 |grep ‘inet addr‘ |awk -F: ‘{print $2}‘ |awk ‘{print $1}‘
192.168.150.53 |
方法5:
[root@localhost ~]# ifconfig eth0|sed -nr ‘2s#^.*addr:(.*) Bcast.*$#\1#g‘p
192.168.150.53 |
方法6:
[root@localhost ~]# ifconfig eth0 |awk ‘/inet addr:/ {print $2}‘ |awk -F: ‘{print $2}‘
192.168.150.53 |
方法7:
[root@localhost ~]# ifconfig eth0 |awk ‘/inet addr:/ {print $2}‘ |awk -F: ‘{print $2}‘
192.168.150.53 |
方法8:
[root@localhost ~]# ifconfig eth0 |awk ‘NR==2 {print $2}‘ |awk -F: ‘{print $2}‘
192.168.150.53 |
方法9:
[root@localhost ~]# ip add |awk -F ‘[ /]+‘ ‘NR==8 {print $3}‘
192.168.150.53 |
