.Dd October 24, 2020 .Dt GETENT 1 .Os .Sh NAME .Nm getent .Nd get entries from administrative database .Sh SYNOPSIS .Nm .Ar database .Op Ar key ... .Sh DESCRIPTION The .Nm utility retrieves and displays entries from the administrative database specified by .Ar database , using the lookup order specified in .Xr nsswitch.conf 5 . The display format for a given .Ar database is as per the .Dq traditional file format for that database.
p The .Ar database argument may be one of:
p l -column ".Li netgroup" -offset indent -compact .Sy Database Ta Sy Display format t Li ethers Ta address name t Li group Ta group:passwd:gid:[member[,member]...] t Li hosts Ta address name [alias ...] t Li netgroup Ta (host,user,domain) [...] t Li networks Ta name network [alias ...] t Li passwd Ta user:passwd:uid:gid:gecos:home_dir:shell t Li protocols Ta name protocol [alias ...] t Li rpc Ta name number [alias ...] t Li services Ta name port/protocol [alias ...] t Li shells Ta /path/to/shell t Li utmpx Ta [time] type: properties .El
p If one or more .Ar key arguments are provided, they will be looked up in .Ar database using the appropriate function. For example, .Dq Li passwd supports a numeric UID or user name; .Dq Li hosts supports an IPv4 address, IPv6 address, or host name; and .Dq Li services supports a service name, service name/protocol name, numeric port, or numeric port/protocol name.
p If no .Ar key is provided and .Ar database supports enumeration, all entries for .Ar database will be retrieved using the appropriate enumeration function and printed. .Sh EXIT STATUS The .Nm utility exits 0 on success, 1 if there was an error in the command syntax, 2 if one of the specified key names was not found in .Ar database , or 3 if there is no support for enumeration on .Ar database . .Sh EXAMPLES Show entry for user sshd from the passwd database: d -literal -offset indent $ getent passwd sshd sshd:*:22:22:Secure Shell Daemon:/var/empty:/usr/sbin/nologin .Ed
p Show entry for TCP from the protocols database: d -literal -offset indent $ getent protocols tcp tcp 6 TCP .Ed
p Show entry for the localhost IPv6 address ::1 from the hosts database: d -literal -offset indent $ getent hosts ::1 ::1 localhost localhost.my.domain .Ed .Sh SEE ALSO .Xr getutxent 3 , .Xr ethers 5 , .Xr group 5 , .Xr hosts 5 , .Xr netgroup 5 , .Xr networks 5 , .Xr nsswitch.conf 5 , .Xr passwd 5 , .Xr protocols 5 , .Xr rpc 5 , .Xr services 5 , .Xr shells 5 .Sh HISTORY A .Nm command appeared in .Nx 3.0 , and was imported into .Fx 7.0 . It was based on the command of the same name in Solaris and Linux.
