These functions use the GETPWENT(3) and GETGRENT(3) system calls to query
users and groups respectively.
Value
They return their results in a data.frame. On windows both
functions return an empty data.frame because windows does not have user
or group ids.
Examples
# list first 6 groups
head(group_ids())
#> group_id group_name
#> 1 0 root
#> 2 1 daemon
#> 3 2 bin
#> 4 3 sys
#> 5 4 adm
#> 6 5 tty
# list first 6 users
head(user_ids())
#> user_id user_name
#> 1 0 root
#> 2 1 daemon
#> 3 2 bin
#> 4 3 sys
#> 5 4 sync
#> 6 5 games
