Connection Management

Connect to a remote host:
```
ssh "<USER>"@"<TARGET>"
```
Test SSH connection with verbose output:
```
ssh -v "<USER>"@"<TARGET>"
```
Execute a single command on the remote host:
```
ssh "<USER>"@"<TARGET>" "<COMMAND>"
```
Remove a host key from known_hosts:
```
ssh-keygen -R "<TARGET>"
```

Key Generation & Authentication

Generate a new SSH key pair:
```
ssh-keygen -t rsa-sha2-512
```

Start the SSH agent and add your private key:

eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_rsa

Retrieve the public key to add to Git or DevOps platforms:
```
cat ~/.ssh/id_rsa.pub
```
