tldrというコマンドを知った。manの表示をわかりやすくしてくれる。Macならbrewで入る。sshの説明ならこう。
$ tldr ssh
ssh
Secure Shell is a protocol used to securely log onto remote systems.
It can be used for logging or executing commands on a remote server.
- Connect to a remote server:
ssh username@remote_host
- Connect to a remote server with a specific identity (private key):
ssh -i path/to/key_file username@remote_host
- Connect to a remote server using a specific port:
ssh username@remote_host -p 2222
- Run a command on a remote server:
ssh remote_host command -with -flags
- SSH tunneling: Dynamic port forwarding (SOCKS proxy on localhost:1080):
ssh -D 1080 username@remote_host
- SSH tunneling: Forward a specific port (localhost:9999 to example.org:80) along with disabling pseudo-[t]ty allocation and executio[n] of remote commands:
ssh -L 9999:example.org:80 -N -T username@remote_host
- SSH jumping: Connect through a jumphost to a remote server (Multiple jump hops may be specified separated by comma characters):
ssh -J username@jump_host username@remote_host
- Agent forwarding: Forward the authentication information to the remote machine (see `man ssh_config` for available options):
ssh -A username@remote_host
おお、わかりやすい。
