LSLOGINS(1) User Commands LSLOGINS(1) NAME lslogins - display information about known users in the system SYNOPSIS lslogins [options] [-s|-u[=UID]] [-g groups] [-l logins] DESCRIPTION Examine the wtmp and btmp logs, /etc/shadow (if necessary) and /etc/passwd and output the desired data. The default action is to list info about all the users in the system. OPTIONS Mandatory arguments to long options are mandatory for short options too. -a, --acc-expiration Display data about the date of last password change and the account expiration date (see shadow(5) for more info). (Requires root privileges.) --btmp-file path Alternate path for btmp. -c, --colon-separate Separate info about each user with a colon instead of a newline. -e, --export Output data in the format of NAME=VALUE. -f, --failed Display data about the users' last failed login attempts. -G, --supp-groups Show information about groups. -g, --groups=groups Only show data of users belonging to groups. More than one group may be specified; the list has to be comma-separated. -h, --help Display help information and exit. -L, --last Display data containing information about the users' last login sessions. -l, --logins=logins Only show data of users with a login specified in logins (user names or user IDS). More than one login may be specified; the list has to be comma-separated. -n, --newline Display each piece of information on a separate line. --noheadings Do not print a header line. --notruncate Don't truncate output. -o, --output list Specify which output columns to print. Use --help to get a list of all supported columns. -p, --pwd Display information related to login by password (see also -afL). -r, --raw Raw output (no columnation). -s, --system-accs Show system accounts. These are by default all accounts with a UID below 1000 (non-inclusive), with the exception of either nobody or nfsnobody (UID 65534). This hardcoded default maybe overwritten by parameters SYS_UID_MIN and SYS_UID_MAX in the file /etc/login.defs. --time-format type Display dates in short, full or iso format. The default is short, this time format is designed to be space efficient and human readable. -u, --user-accs Show user accounts. These are by default all accounts with UID above 1000 (inclu‐ sive), with the exception of either nobody or nfsnobody (UID 65534). This hard‐ coded default maybe overwritten by parameters UID_MIN and UID_MAX in the file /etc/login.defs. -V, --version Display version information and exit. --wtmp-file path Alternate path for wtmp. -Z, --context Display the users' security context. -z, --print0 Delimit user entries with a nul character, instead of a newline. NOTES The default UID thresholds are read from /etc/login.defs. EXIT STATUS 0 if OK, 1 if incorrect arguments specified, 2 if a serious error occurs (e.g. a corrupt log). SEE ALSO group(5), passwd(5), shadow(5), utmp(5) HISTORY The lslogins utility is inspired by the logins utility, which first appeared in FreeBSD 4.10.
