sys_id(4) sys_id(4)
sys_id - system identification (hostname) file
The file /etc/sys_id 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
/etc/rc2.d/S20sysetup and the contents are passed as a parameter to
hostname(1) to initialize the system name. Once this has been done, this
name is returned by the commands hostnam
and by the
system calls gethostname(2) and uname(2). uname(1) returns only the
first eight characters up to the first period.
/etc/sys_id
hostname(1), uname(1), gethostname(2), uname(2), hostname(5).
