Network Automating ssh connection
I want to create a script for the ssh connection that handles any input. Be it IP or DNS.
And instead of typing in giant commands, I'd like to downplay it and treat it.

I imagined the following command:

i machine
or
i machine.exemple.com.fr
or
i 111.222.333.4444

Login attempts should be made with devops, or with matheus.

I do not know much about shell script I'm reading a few hours and working on the script below.
Can you help me?
Thank you.

> /bin/i && chmod +x /bin/i && vi /bin/i
bash /bin/i

Code:
#!/bin/bash

if [ "$1" == "" ]
then
clear
echo "how to use:"
echo "i 111.222.333.444"
echo "i name"
echo "i name.exemple.com.fr"
echo ""
fi

#verifying that the input is a valid ip
if [[ $1 =~ ^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+$ ]]; then
      clear
      echo "Success! Accessing $1 with devops"
      ssh devops@$1
 elif
      clear
      echo "Oops! Could not access with devops, trying to access as matheus"
      ssh -i /home/devops/.ssh/matheus_rsa matheus@$1
else
      clear
      echo "Could not connect! Here's some information to access the provider platform."
      whois $1 | grep -E "mnt-by|OrgName|nserver"
      getent hosts $1
fi

#-f If you have text
if [ -f $1 ]; then
      clear
      echo "Success! Accessing $1 with devops"
      ssh devops@$1.exemple.com.fr
  elif
      clear
      echo "[1] Trying to connect..."
      ssh devops@$1
  elif
      clear
      echo "Oops! Could not access with devops, trying to access as matheus"
      ssh -i /home/devops/.ssh/matheus_rsa matheus@$1.exemple.com.fr
  elif
      clear
      echo "[2] Trying to connect..."
      ssh -i /home/devops/.ssh/matheus_rsa matheus@$1
else
      echo "Could not connect! Here's some information to access the provider platform."
      whois $1 | grep -E "mnt-by|OrgName|nserver"
      getent hosts $1
fi

ssh-keysign

SSH-KEYSIGN(8)						    BSD System Manager's Manual 					    SSH-KEYSIGN(8)

NAME

     ssh-keysign -- ssh helper program for host-based authentication

SYNOPSIS

     ssh-keysign

DESCRIPTION

     ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication with
     SSH protocol version 2.

     ssh-keysign is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting
     EnableSSHKeysign to ``yes''.

     ssh-keysign is not intended to be invoked by the user, but from ssh(1).  See ssh(1) and sshd(8) for more information about host-based authen-
     tication.

FILES

     /etc/ssh/ssh_config
	     Controls whether ssh-keysign is enabled.

     /etc/ssh/ssh_host_dsa_key
     /etc/ssh/ssh_host_ecdsa_key
     /etc/ssh/ssh_host_rsa_key
	     These files contain the private parts of the host keys used to generate the digital signature.  They should be owned by root, read-
	     able only by root, and not accessible to others.  Since they are readable only by root, ssh-keysign must be set-uid root if host-
	     based authentication is used.

     /etc/ssh/ssh_host_dsa_key-cert.pub
     /etc/ssh/ssh_host_ecdsa_key-cert.pub
     /etc/ssh/ssh_host_rsa_key-cert.pub
	     If these files exist they are assumed to contain public certificate information corresponding with the private keys above.

SEE ALSO

     ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)

HISTORY

     ssh-keysign first appeared in OpenBSD 3.2.
