Thanks seg for the tip. I had forgotten the logins command.
vr_mari: not sure about why you insist telling you use getenv while the output clearly shows you run getent. By the way, getent not only look in the /etc files but also in whatever remote database (nis, ldap, ...) might be declared in nsswitch.conf.

getent
GETENT(1) BSD General Commands Manual GETENT(1)
NAME
getent -- get entries from administrative databases
SYNOPSIS
getent database [key ...]
getcap database [key ...]
DESCRIPTION
The getent program retrieves and displays entries from the administrative database specified by database, using the lookup order specified in
nsswitch.conf(5). The display format for a given database is as per the ``traditional'' file format for that database.
database may be one of:
Database Display format
disktab entry
ethers address name
gettytab entry
group group:passwd:gid:[member[,member]...]
hosts address name [alias ...]
netgroup (host,user,domain) [...]
networks name network [alias ...]
passwd user:passwd:uid:gid:gecos:home_dir:shell
printcap entry
protocols name protocol [alias ...]
rpc name number [alias ...]
services name port/protocol [alias ...]
shells /path/to/shell
If one or more key arguments are provided, they will be looked up in database using the appropriate function. For example, passwd supports a
numeric UID or user name; hosts supports an IPv4 address, IPv6 address, or host name; and services supports a service name, service name/pro-
tocol name, numeric port, or numeric port/protocol name.
If no key is provided and database supports enumeration, all entries for database will be retrieved using the appropriate enumeration func-
tion and printed.
For cgetcap(3) style databases (disktab, printcap) specifying a key, lists the entry for that key, and specifying more arguments after the
key are used as fields in that key, and only the values of the keys are returned. For boolean keys true is returned if the key is found. If
a key is not found, then false is always returned.
DIAGNOSTICS
getent 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 database, or 3
if there is no support for enumeration on database.
