- sys_id - system identification (hostname) file
-
- DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
- The file /_e_t_c/_s_y_s__i_d contains the name by which the system is known on
- communications networks such as the Internet and UUCP. The name can be
- up to 64 alphanumeric characters long and can include periods and
- hyphens. Periods are not part of the name but serve to separate
- components of a domain-style name. For example:
-
- iris.widgets.com
-
- During system startup this file is read by the script
- /_e_t_c/_r_c_2._d/_S_2_0_s_y_s_e_t_u_p and the contents are passed as a parameter to
- _h_o_s_t_n_a_m_e(1) to initialize the system name. Once this has been done, this
- name is returned by the commands _h_o_s_t_n_a_m_e(1) and _u_n_a_m_e(1) and by the
- system calls _g_e_t_h_o_s_t_n_a_m_e(2) and _u_n_a_m_e(2). _u_n_a_m_e(1) returns only the
- first eight characters up to the first period.
