In my work, I need to modify two files:

File one: / etc/vmware/networking

File 2: / etc/vmware/vmnet8/dhcpd/dhcpd.conf

# Configuration file for ISC 2.0 vmnet-dhcpd operating on vmnet8.## This file was automatically generated by the VMware configuration program.# See Instructions below if you want to modify it.## We set domain-name-servers to make some DHCP clients happy# (dhclient as configured in SuSE, TurboLinux, etc.). # We also supply a domain name to make pump (Red Hat 6.x) happy.# VMNET DHCP Configuration.

End of "DO NOT MODIFY SECTION" #

Demand:

Change "192.168.43" in both files to "202.16.22", but sometimes "192.168.43" will show other IP values, and the target string "202.16.22" may be set separately as the environment changes.

Based on this requirement, I wrote the following test script:

For file one:

The #! / bin/bash# $vmnat_subnet_old variable represents the original subnet configuration of vmnat8. Note that only the first three segments of vmnat_subnet_old= `grep "VNET_8_HOSTONLY_SUBNET" / etc/vmware/networking are truncated. | cut-d''- f 3` # $vmnat_subnet_new indicates the target configuration of the vmnat8 subnet. Note that only the first three paragraphs vmnat_subnet_new='192.168.40'cp / etc/vmware/networking / etc/vmware/networking_bak0sed-I'/ VNET_8_HOSTONLY_SUBNET/s/' "$vmnat_subnet_old" /'"$vmnat_subnet_new" /'/ etc/vmware/networkinggrep "$vmnat_subnet_new" / etc/vmware/networkingcp / etc/vmware/networking_bak0 / etc/vmware/networking are intercepted.

For file two:

The #! / bin/bash# $vmnat_subnet_new variable represents the target configuration of the vmnat8 subnet. Note that only the first three segments of vmnat_subnet_new='192.168.40'# $vmnat_subnet_old variable are truncated to represent the original subnet configuration of vmnat8. Note that only the first three segments of vmnat_subnet_old= `grep "VNET_8_HOSTONLY_SUBNET" / etc/vmware/networking are truncated | sed's vmnat_subnet_new... "vmnat_subnet_new" / g' / "$vmnat_subnet_new" / g'/ / Etc/vmware/vmnet8/dhcpd/dhcpd.confgrep "$vmnat_subnet_new" / etc/vmware/vmnet8/dhcpd/dhcpd.confcp / etc/vmware/vmnet8/dhcpd/dhcpd.conf_bak0 / etc/vmware/vmnet8/dhcpd/dhcpd.conf

Advantages:

You don't have to know in advance what the character to replace is (in this case: 192.168.43), just know what you want to replace (in this case: 202.16.22).

Oh, a screenshot of my work desktop.
