SSH-COPY-ID(1)							SSH-COPY-ID(1)

NAME
       ssh-copy-id  -  install	your  public  key in a remote machine's autho‐
       rized_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  and
       append  the  indicated  identity	 file  to that machine's ~/.ssh/autho‐
       rized_keys file.

       If the  -i  option  is  given  then  the	 identity  file	 (defaults  to
       ~/.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 fin‐
       gerprints  (by  whatever	 means)	 it  uses  ssh	to  append   them   to
       ~/.ssh/authorized_keys  on  the	remote machine (creating the file, and
       directory, if necessary.)

NOTES
       This program does not modify the permissions of any pre-existing	 files
       or  directories.	 Therefore,  if the remote sshd has StrictModes set in
       its  configuration,  then  the  user's	home,	~/.ssh	 folder,   and
       ~/.ssh/authorized_keys file may need to have group writability disabled
       manually, e.g. via

	     chmod go-w ~ ~/.ssh ~/.ssh/authorized_keys

       on the remote machine.
