[Solved] Help to remove a line from a file

Hi,

I just upgraded one my server to latest version RHEL, I have many users who will do SSH from another server. I wanted to update all of the users home directory and remove the security key. For example.
/home/XYZ/.ssh/known_hosts and remove this hostsname.
Please see below and advise. Thanks.


Code:
 
#!/bin/ksh -e
XYZ='ls -1 /home'  ## need to list each of the home directory
for USERS in /$XYZ/.ssh/known_hosts ' ## each users home directory.
do
sed 's/txus03/g'   ##  remove the line txus03, replace with nothing
done

createhomedir(1)					    BSD General Commands Manual 					  createhomedir(1)

NAME
createhomedir -- create and populate home directories on the local computer. SYNOPSIS
createhomedir [-scbalh] [-n directoryDomainName] [-u username] DESCRIPTION
createhomedir provides several options for creating and populating home directories. OPTIONS
-s creates home directories for server home paths only (default). -c creates home directories for local home paths only. -b creates home directories for both server and local home paths. -a creates home directories for users defined in all directory domains of the server's search path. -l creates home directories for users defined in the local directory domain. -n directoryDomainName creates home directories for users defined in a specific directory domain in the server's search path. -u username creates a home directory for a specific user defined in the domain(s) identified in the -a, -l, or -n parameter. If you omit the -a, -l, and -n parameters when you use the -u parameter, -a is assumed. -i reads username list from standard input and creates specified home directories. Each username should be on its own line. -h usage help. FILES
/usr/sbin/createhomedir location of tool CAVEATS
When using the -a option, search limits of various directory servers (such as Open Directory or Active Directory) can prevent all possible home directories from being created. In this case, you may need to specify the usernames explicitly. Mac OS X June 1, 2019 Mac OS X
