relative path name
A path name that does not begin with a slash (
/). It indicates that a file’s location is
given relative to your current working directory, and that the search begins there
(instead of at the root directory). For example,
dir1/file2 searches for the direc-
tory
dir1 in your current working directory; then
dir1 is searched for the file file2.
root directory
(1) The highest level directory of the hierarchical file system, from which all other files
branch. In HP-UX, the slash (
/
) character refers to the root directory. The root direc-
tory is the only directory in the file system that is its own parent directory.
(2) Each process has associated with it a concept of a root directory for the purpose of
resolving path name searches for those paths beginning with slash (
/). A process’s root
directory need not be the root directory of the root file system, and can be changed by the
chroot(1M) command or chroot(2) system call. Such a directory appears to the process
involved to be its own parent directory.
root volume The mass storage volume which contains the boot area (which contains the HP-UX ker-
nel) and the root directory of the HP-UX file system.
saved group ID
Every process has a saved group ID that retains the process’s effective group ID from
the last successful exec(2) or
setresgid() (see setresuid (2)), or from the last
superuser call to setgid() (see setuid(2)) or setresuid(2). setgid() permits a pro-
cess to set its effective group ID to this remembered value. Consequently, a process that
executes a program with the set-group-ID bit set and with a group ID of 5 (for example)
can set its effective group ID to 5 at any time until the program terminates. See exec(2),
setuid(2), saved user ID, effective group ID, and set-group-ID bit. The saved group
ID is also known as the saved set-group-ID.
saved process group ID
Every process has a saved process group ID that retains the process’s group ID from the
last successful exec(2). See setpgrp (2), termio (7), and process group ID.
saved user ID Every process has a saved user ID that retains the process’s effective user ID from the
last successful exec(2) or setresuid (2), or from the last superuser call to setuid (2).
setuid(2) permits a process to set its effective user ID to this remembered value. Conse-
quently, a process which executes a program with the set-user-ID bit set and with an
owner ID of 5 (for example) can set its effective user ID to 5 at any time until the pro-
gram terminates. See exec(2), setuid(2), saved group ID, effective user ID, and set-
user-ID bit. The saved user ID is also known as the saved set-user-ID.
saved set-group-ID
See saved group ID.
saved set-user-ID
See saved user ID.
SCCS See Source Code Control System.
Source Code Control System (SCCS)
A set of HP-UX commands that enables you to store changes to an SCCS file as separate
‘‘units’’ (called deltas). These units, each of which contains one or more textual changes
to the file, can then be applied to or excluded from the SCCS file to obtain different ver-
sions of the file. The commands that make up SCCS are admin(1), cdc(1), delta (1),
get(1), prs(1), rmdel(1), sact(1), sccsdiff(1), unget(1), val(1), and what(1).
SCCS file An ordinary text file that has been modified so the Source Code Control System
(SCCS) can be used with it. This modification is done automatically by the admin(1)
command. See also delta.
secondary prompt
One or more characters that the shell prints on the display, indicating that more input is
needed. This prompt is not encountered nearly as frequently as the shell’s primary
prompt (see prompt). When it occurs, it is usually caused by an omitted right quote on a
string (which confuses the shell), or when you enter a shell programming language
control-flow construct (such as a
for construct) from the command line. By default, the
shell’s secondary prompt is the greater-than sign (>), but you can re-define it by setting
