Got the below error on my CentOS 8 server. On CentOS servers, lexgrog command is provided by man-db package and it might not be installed on your server.

bash: /usr/bin/lexgrog: No such file or directory

Follow the below steps to install man-db package.

Step 1 : Log into CentOS 8 server as ‘root’ user

Step 2 : Run the command ‘rpm -qa | grep -i man-db’ to check whether man-db is already installed or not

man-db package is not installed on the above server. If package is already installed, the error might be due to incorrect path of the binary.
