54.Nm
55is a program to hold private keys used for public key authentication
56(RSA, DSA).
57The idea is that

72The default is
73.Pa /tmp/ssh-XXXXXXXXXX/agent.\*(Ltppid\*(Gt .
74.It Fl c
75Generate C-shell commands on
76.Dv stdout .
77This is the default if
78.Ev SHELL
79looks like it's a csh style of shell.
80.It Fl s
81Generate Bourne shell commands on
82.Dv stdout .
83This is the default if
84.Ev SHELL
85does not look like it's a csh style of shell.
86.It Fl k
87Kill the current agent (given by the
88.Ev SSH_AGENT_PID
89environment variable).
90.It Fl t Ar life
91Set a default value for the maximum lifetime of identities added to the agent.
92The lifetime may be specified in seconds or in a time format specified in
93.Xr sshd_config 5 .
94A lifetime specified for an identity with
95.Xr ssh-add 1
96overrides this value.
97Without this option the default maximum lifetime is forever.
98.It Fl d
99Debug mode.
100When this option is specified
101.Nm
102will not fork.
103.El
104.Pp
105If a commandline is given, this is executed as a subprocess of the agent.
106When the command dies, so does the agent.
107.Pp
108The agent initially does not have any private keys.
109Keys are added using
110.Xr ssh-add 1 .
