#### Usage Examples:
**Configure network device _eth0_ to DHCP mode**
```
awk -f changeInterfaces.awk /etc/network/interfaces device=eth0 mode=dhcp
awk -f changeInterface.awk /etc/network/interfaces device=eth0 mode=dhcp
```
**Add a network device _p3p1_ with static settings**
```
awk -f changeInterfaces.awk /etc/network/interfaces device=p3p1 action=add mode=static address=192.168.202.1 netmask=255.255.255.0 gateway=192.168.202.254
awk -f changeInterface.awk /etc/network/interfaces device=p3p1 action=add mode=static address=192.168.202.1 netmask=255.255.255.0 gateway=192.168.202.254
```
If _p3p1_ already exists and configured as DHCP, it will automatically modify to static interface with all the input settings.

If _p3p1_ already exists and configured as static, it will overwrite the existing field or add the field if it is new.

**Delete an interface entry**
```
awk -f changeInterfaces.awk /etc/network/interfaces device=eth1 action=remove
awk -f changeInterface.awk /etc/network/interfaces device=eth1 action=remove
```

**Remove `network` & `broadcast` fields and add (or modify if exists) `dns-nameservers` & `foo` fields**
```
awk -f changeInterfaces.awk /etc/network/interfaces device=eth1 mode=static network= broadcast= foo=bar 'dns-nameservers=10.0.10.1 192.168.200.5 192.168.202.254'
awk -f changeInterface.awk /etc/network/interfaces device=eth1 mode=static network= broadcast= foo=bar 'dns-nameservers=10.0.10.1 192.168.200.5 192.168.202.254'
