ID(1L) ID(1L) NNAAMMEE id - print real and effective UIDs and GIDs SSYYNNOOPPSSIISS iidd [-gnruG] [--group] [--name] [--real] [--user] [--groups] [username] DDEESSCCRRIIPPTTIIOONN This manual page documents the GNU version of iidd. iidd prints information about the given user, or the process running it if no user is specified. By default, it prints the real user ID, real group ID, effective user ID if dif- ferent from the real user ID, effective group ID if dif- ferent from the real group ID, and supplemental group IDs. It prints each of these values preceded by a string iden- tifying it and followed by the corresponding user or group name in parentheses. The options cause iidd to print only part of the above information. OOPPTTIIOONNSS -_g, --_g_r_o_u_p Print only the group ID. -_n, --_n_a_m_e Print the user or group name instead of the ID num- ber. Requires -_u, -_g, or -_G. -_r, --_r_e_a_l Print the real, instead of effective, user or group ID. Requires -_u, -_g, or -_G. -_u, --_u_s_e_r Print only the user ID. -_G, --_g_r_o_u_p_s Print only the supplementary groups. The long-named options can be introduced with `+' as well as `--', for compatibility with previous releases. Even- tually support for `+' will be removed, because it is incompatible with the POSIX.2 standard. 1
