“-bash: route: command not found” on CentOS/RHEL 8

by

The old command to set the default route is route. If no options are used, it will display a list of all routes that are currently defined on this host. When using the route command without options, it will always try to resolve the name for a given IP address, which takes some time. If you don’t want any name resolution to be performed, use the option -n, which makes the command a lot faster. The equivalent command with ip is as follows:

$ ip r

where r stands for route.

By default route command is not available in CentOS/RHEL 8 minimal installation and other Linux distributions. route command is available by installing package net-tools. ip route show command can be used instead of route command to check listening ports and services on CentOS/RHEL 8 minimal installation.

This post describes How to resolve “-bash: route: command not found” on CentOS/RHEL 8.

The error below shows that the route command is not installed on the system.

# route -n
-bash: route: command not found
#

Step 1. Package Installation: Run the following command to install net-tools package:

# dnf install net-tools
CentOS-8 – AppStream
…………………….
Installed:
  net-tools-2.0-0.51.20160912git.el8.x86_64

Complete!
#

Step 2. Verification: Verify the installation: Run the following commands to verify the installation:

# which netstat
/usr/sbin/route
#

To display the routing table, use the below command:

# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface

Final Thoughts

As mentioned in the previous section, the ip utility is a replacement for several utilities including ifconfig and ‘route’, it is included in the iproute2 package. Routes can be seen by running ip route or ip r for short. There are additional route commands for adding or deleting such as ip route del unreachable 10.1.0.0/24, where “unreachable” is the route name and “10.1.0.0/24” is the route.
