These fields are 9 as follows: 10 group Name of the group. 11 passwd Group's _e_n_c_r_y_p_t_e_d password. 12 gid The group's decimal ID. 13 member Group members. 14 15 The _g_r_o_u_p field is the group name used for granting file access to users 16 who are members of the group. The _g_i_d field is the number associated 17 with the group name. They should both be unique across the system (and 18 often across a group of systems) since they control file access. The 19 _p_a_s_s_w_d field is an optional _e_n_c_r_y_p_t_e_d password. This field is rarely 20 used and an asterisk is normally placed in it rather than leaving it 21 blank. The _m_e_m_b_e_r field contains the names of users granted the priv- 22 iledges of _g_r_o_u_p. The member names are separated by commas with out 23 spaces or newlines. A user is automatically in a group if that group was 24 specified in their /_e_t_c/_p_a_s_s_w_d entry and does not need to be added to 25 that group in the /_e_t_c/_g_r_o_u_p _f_i_l_e. 26 27FFIILLEESS 28 /etc/group 29 30SSEEEE AALLSSOO 31 setgroups(2), initgroups(3), crypt(3), passwd(1), passwd(5) 32 33BBUUGGSS 34 The passwd(1) command does not change the ggrroouupp passwords. 35 36HHIISSTTOORRYY 37 A ggrroouupp file format appeared in Version 6 AT&T UNIX. 38 39BSD Experimental April 29, 1991 2 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67
