^[[1mDESCRIPTION^[[0m
^[[1msshM-bM-^@M-^Padd ^[[22madds RSA or DSA identities to the authentication agent,
sshM-bM-^@M-^Pagent(1). When run without arguments, it adds the files
^[[4m$HOME/.ssh/id_rsa^[[24m, ^[[4m$HOME/.ssh/id_dsa^[[24m and ^[[4m$HOME/.ssh/identity^[[24m. AlternaM-bM-^@M-^P
tive file names can be given on the command line. If any file requires a
passphrase, ^[[1msshM-bM-^@M-^Padd ^[[22masks for the passphrase from the user. The
passphrase is read from the userM-bM-^@M-^Ys tty. ^[[1msshM-bM-^@M-^Padd ^[[22mretries the last
passphrase if multiple identity files are given.
The authentication agent must be running and must be an ancestor of the
current process for ^[[1msshM-bM-^@M-^Padd ^[[22mto work.
The options are as follows:
^[[1mM-bMM-^Rl ^[[22mLists fingerprints of all identities currently represented by the
agent.
^[[1mM-bMM-^RL ^[[22mLists public key parameters of all identities currently repreM-bM-^@M-^P
sented by the agent.
^[[1mM-bMM-^Rd ^[[22mInstead of adding the identity, removes the identity from the
agent.
^[[1mM-bMM-^RD ^[[22mDeletes all identities from the agent.
^[[1mM-bMM-^Rx ^[[22mLock the agent with a password.
^[[1mM-bMM-^RX ^[[22mUnlock the agent.
^[[1mM-bMM-^Rt ^[[4m^[[22mlife^[[0m
Set a maximum lifetime when adding identities to an agent. The
lifetime may be specified in seconds or in a time format speciM-bM-^@M-^P
fied in sshd_config(5).
^[[1mM-bMM-^Rc ^[[22mIndicates that added identities should be subject to confirmation
before being used for authentication. Confirmation is performed
by the SSH_ASKPASS program mentioned below. Successful confirmaM-bM-^@M-^P
tion is signaled by a zero exit status from the SSH_ASKPASS proM-bM-^@M-^P
gram, rather than text entered into the requester.
^[[1mM-bMM-^Rs ^[[4m^[[22mreader^[[0m
Add key in smartcard ^[[4mreader^[[24m.
^[[1mM-bMM-^Re ^[[4m^[[22mreader^[[0m
Remove key in smartcard ^[[4mreader^[[24m.
^[[1mFILES^[[0m
$HOME/.ssh/identity
Contains the protocol version 1 RSA authentication identity of
the user.
$HOME/.ssh/id_dsa
Contains the protocol version 2 DSA authentication identity of
the user.
$HOME/.ssh/id_rsa
Contains the protocol version 2 RSA authentication identity of
the user.
Identity files should not be readable by anyone but the user. Note that
^[[1msshM-bM-^@M-^Padd ^[[22mignores identity files if they are accessible by others.
^[[1mENVIRONMENT^[[0m
DISPLAY and SSH_ASKPASS
If ^[[1msshM-bM-^@M-^Padd ^[[22mneeds a passphrase, it will read the passphrase from
the current terminal if it was run from a terminal. If ^[[1msshM-bM-^@M-^Padd^[[0m
does not have a terminal associated with it but DISPLAY and
SSH_ASKPASS are set, it will execute the program specified by
SSH_ASKPASS and open an X11 window to read the passphrase. This
is particularly useful when calling ^[[1msshM-bM-^@M-^Padd ^[[22mfrom a ^[[4m.Xsession^[[24m or
related script. (Note that on some machines it may be necessary
to redirect the input from ^[[4m/dev/null^[[24m to make this work.)
SSH_AUTH_SOCK
Identifies the path of a unixM-bM-^@M-^Pdomain socket used to communicate
with the agent.
^[[1mDIAGNOSTICS^[[0m
Exit status is 0 on success, 1 if the specified command fails, and 2 if
^[[1msshM-bM-^@M-^Padd ^[[22mis unable to contact the authentication agent.
^[[1mAUTHORS^[[0m
OpenSSH is a derivative of the original and free ssh 1.2.12 release by
Tatu Ylonen. Aaron Campbell, Bob Beck, Markus Friedl, Niels Provos, Theo
de Raadt and Dug Song removed many bugs, reM-bM-^@M-^Padded newer features and creM-bM-^@M-^P
ated OpenSSH. Markus Friedl contributed the support for SSH protocol
versions 1.5 and 2.0.
