53.Pp
54.Ar database
55may be one of:
56.Bl -column "protocols" "user:passwd:uid:gid:gecos:home_dir:shell" -offset indent -compact
57.It Sy Database Ta Sy Display format
58.It disktab Ta entry
59.It ethers Ta address name
60.It gettytab Ta entry
61.It group Ta group:passwd:gid:[member[,member]...]
62.It hosts Ta address name [alias ...]
63.It netgroup Ta (host,user,domain) [...]
64.It networks Ta name network [alias ...]
65.It passwd Ta user:passwd:uid:gid:gecos:home_dir:shell
66.It printcap Ta entry
67.It protocols Ta name protocol [alias ...]
68.It rpc Ta name number [alias ...]
69.It services Ta name port/protocol [alias ...]
70.It shells Ta /path/to/shell

72.Pp
73If one or more
74.Ar key
75arguments are provided, they will be looked up in
76.Ar database
77using the appropriate function.
78For example,
79.Sy passwd
