Lookup Users and Groups on a system

Source: R/id.R

These functions use the GETPWENT(3) and GETGRENT(3) system calls to query users and groups respectively.

group_ids()

user_ids()

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
