Damien Miller6e1057c2002-01-22 23:05:59 +1100[diff] [blame]58When run without arguments, it adds the files

64If any file requires a passphrase,

Damien Miller22c77262000-04-13 12:26:34 +1000[diff] [blame]66asks for the passphrase from the user.
Ben Lindstromaafff9c2001-05-06 03:01:02 +0000[diff] [blame]67The passphrase is read from the user's tty.
Ben Lindstrom12de6162001-04-10 02:46:54 +0000[diff] [blame]68.Nm
69retries the last passphrase if multiple identity files are given.

71The authentication agent must be running and must be an ancestor of

Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]82.It Fl d
83Instead of adding the identity, removes the identity from the agent.
84.It Fl D
85Deletes all identities from the agent.

Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]129may be necessary to redirect the input from
