Ssh-copy-id command

The SSH-copy-id command can install the local SSH public key file to the account corresponding to the remote host.

I have been manually using SCP and SSH commands to execute this task. I just found this convenient command!

Name

Ssh-copy-ID-install your public key in a remote machine's authorized_keys

 

Synopsis

Ssh-copy-ID [-I [identity_file] [user @] Machine

 

Description

Ssh-copy-ID is a script that uses SSH to log into a remote machine (presumably using a login password, so Password Authentication shocould be enabled, unless you 've

Done some clever use of multiple identities)

 

It also changes the permissions of the remote user's home ,~ /. Ssh, and ~ /. Ssh/authorized_keys to remove group writability (which wowould otherwise prevent you from

Logging in, if the remote sshd has strictmodes set in its configuration ).

 

If the-I option is given then the identity file (defaults ~ /. Ssh/id_rsa.pub) is used, regardless of whether there are any keys in your ssh-agent. Otherwise, if

This:

 

Ssh-add-l

 

Provides any output, it uses that in preference to the identity file.

 

If the-I option is used, or the ssh-add produced no output, then it uses the contents of the Identity file. Once it has one or more fingerprints (by whatever

Means) It uses SSH to append them ~ /. Ssh/authorized_keys on the remote machine (creating the file, and directory, if necessary)
