NAME
getuid, id - get user identity
SYNOPSIS
getuid [ - ] [ arguments ]
id
DESCRIPTION
Getuid prints on its standard output information about its invoker,
based on the effective user id, as presented in the password file.
With no arguments, getuid prints the login id of its invoker. Argu‐
ments select which information to print:
user login id
group group id
passwd encrypted password
uid numerical user id
gid numerical group id
acct GCOS account number
bin GCOS output bin
home home directory
shell default shell
If the optional - or more than one argument is present, the information
is displayed in the form
user=name
as suitable for setting environment variables in the shell.
Id prints the effective userid and groupid numerically, and, if possi‐
ble, textually
FILES
/etc/passwd
/etc/group

BUGS
Getuid reports the default group for the user, not the current effec‐
tive group id.
The login id reported is the first one in the password file with the
correct numerical user id, not necessarily the login for the current
session.
