.TH INSTALL.CF 5L PUCC
.SH NAME
install.cf \- a check list to confirm correct installations
.SH DESCRIPTION
.PP
.IR Install (1L)
allows the system administrator to update important files
while maintaining a backup copy of any old versions.
.I Install
checks the actions of the superuser against a
list of important files, to prevent careless security
breaches.
The \fB\-C\fP option controls which
checklist \fIinstall\fP examines.
.PP
.I Install
searches \fIinstall.cf\fP for an
.IR sh (1)
\fIglob\fP expression that matches
the file to be installed.
When it finds a matching expression it checks
the proposed owner, group, and mode against those listed in
the checklist; any variation causes
.I install
to abort.
This mechanism is provided to protect the superuser from installing,
for instance, the shell setuid:
.sp 1
X install -m7555 -o root -g wheel sh /bin
.sp 1
(note the extra \`5\').
.PP
Each data line in \fIinstall.cf\fP consists of 6 fields;
.br
X a glob expression
.br
X a mode, in either octal or symbolic format
.br
X a symbolic owner
.br
X a symbolic group
.br
X a \fIstrip\fR(1) or \fIranlib\fR(1) indicator
.br
X an optional comment
.br
Blank lines and lines which begin with a pound sign (#) are ignored.
.PP
If the glob expression begins with a slash (\*(lq/\*(rq)
it is matched against the full \fItarget\fP,
otherwise it is matched against only the last component of the \fItarget\fP.
(For the definition of \fItarget\fP see \fIinstall\fP(1L).)
For instance, the expression
.br
X *.a
.br
will match every library (file ending in \`.a\'), while
.br
X /lib/*.a
.br
will only match libraries in \*(lq/lib\*(rq.
.PP
The mode field may be filled with either an octal number (discouraged)
or a symbolic mode (see
.IR ls (1)).
Any bit specified as on \fBmust\fP be on,
any bit specified as off (\-) \fBmust\fP be off.
The symbolic mode may also include \`?\' to indicate an optional bit.
For instance the mode
.br
X \-r?\-r\-\-r\-\-
.br
will match either \-rw\-r\-\-r\-\- (0644) or \-r\-\-r\-\-r\-\- (0444).
If a setuid, setgid, or sticky bit is set without the underlying
execute bit being set the \`s\' or \`t\' should be given in
uppercase.
.PP
Some combinations of modes are not expressible in the above format,
e.g. 0755 with an optional setgid bit. For such modes a special
format is allowed:
.br
X \fImode\fP/\fIoptional-mode\fP
.br
in which case all the bits in \fIoptional-mode\fP are taken as optional.
To express our example mode one might use:
.br
X drwxr-xr-x/02000
.br
(this is a good mode for a directory under SunOS).
.PP
The type bit in the symbolic mode may be any of the \fIfind\fP(1) type
bits, or an exclamation point (\*(lq!\*(rq). The ! is used to indicate files
that should \fBnever\fP exist, and may prefix an auxilary file type.
.PP
The owner (group) column may either contain an asterisk (\*(lq*\*(rq) or
an alphanumeric identifier.
If an asterisk is given any valid owner (group) may be used.
No numeric user (group) identifiers are allowed.
A owner (group) name may be prefixed by an exclamation point (\*(lq!\*(rq)
which indicates that only this owner (group) is not allowed.
.PP
The strip/ranlib indicator follows this table
.RS
.TS
l l.
n do not run either \fIstrip\fP(1) or \fIranlib\fP(1)
l run \fIranlib\fP(1)
s run \fIstrip\fP(1)
* allows either to be run, requires neither
.TE
.RE
It makes no sense (to the authors) to run
both \fIstrip\fP(1) and \fIranlib\fP(1).
.PP
.I Install
displays the comment section when the file is installed.
.PP
A double quote (\*(rq) substitutes the entry from the previous line.
An equals sign (=) substitutes \fIinstall\fP's default value for a field.
.PP
The tool \fIinstck\fP(1L) may be used to generate configuration
files for named files (assuming the current ones are correct).
