No escape mechanism is supported within

<DL COMPACT>

<DT id="2"><B>PRUNEFS</B><DD>
|
|
A whitespace-separated list of file system types (as used in <B>/etc/mtab</B>)
|
|
which should not be scanned by
|
|
<B><A HREF="/cgi-bin/man/man2html?8+updatedb">updatedb</A></B>(8).
|
|
|
|
The file system type matching is case-insensitive. By default, no file system
|
|
types are skipped.
|
|
<P>
|
|
When scanning a file system is skipped,
|
|
all file systems mounted in the subtree are skipped too,
|
|
even if their type does not match any entry in <B>PRUNEFS</B>.
|
|
<P>
|
|
<DT id="3"><B>PRUNENAMES</B><DD>
|
|
A whitespace-separated list of directory names (without paths) which should not
|
|
be scanned by
|
|
<B><A HREF="/cgi-bin/man/man2html?8+updatedb">updatedb</A></B>(8).
|
|
|
|
By default, no directory names are skipped.
|
|
<P>
|
|
Note that only directories can be specified, and no pattern mechanism (e.g.
|
|
globbing) is used.
|
|
<P>
|
|
<DT id="4"><B>PRUNEPATHS</B><DD>
|
|
A whitespace-separated list of path names of directories which should not be
|
|
scanned by
|
|
<B><A HREF="/cgi-bin/man/man2html?8+updatedb">updatedb</A></B>(8).
|
|
|
|
Each path name must be exactly in the form
|
|
in which the directory would be reported by
|
|
<B><A HREF="/cgi-bin/man/man2html?1+locate">locate</A></B>(1).
|
|
|
|
<P>
|
|
By default, no paths are skipped.
|
|
<P>
|
|
<DT id="5"><B>PRUNE_BIND_MOUNTS</B><DD>
|
|
One of the strings <B>0</B>, <B>no</B>, <B>1</B> or <B>yes</B>.
|
|
If
|
|
<B>PRUNE_BIND_MOUNTS</B>
|
|
|
|
is <B>1</B> or <B>yes</B>,
|
|
bind mounts are not scanned by
|
|
<B><A HREF="/cgi-bin/man/man2html?8+updatedb">updatedb</A></B>(8).
|
|
|
|
All file systems mounted in the subtree of a bind mount are skipped as well,
|
|
even if they are not bind mounts.
|
|
As an exception, bind mounts of a directory on itself are not skipped.
|
|
<P>
|
|
By default, bind mounts are not skipped.

<H2>NOTES</H2>
|
|
|
|
When a directory is matched by <B>PRUNEFS</B>, <B>PRUNENAMES</B> or
|
|
<B>PRUNEPATHS</B>,
|
|
<B><A HREF="/cgi-bin/man/man2html?8+updatedb">updatedb</A></B>(8)
|
|
|
|
does not scan the contents of the directory.
|
|
The path of the directory itself is, however, entered in the created database.
|
|
For example, if
|
|
<I>/tmp</I>
|
|
|
|
is in <B>PRUNEPATHS</B>,
|
|
<B><A HREF="/cgi-bin/man/man2html?1+locate">locate</A></B>(1)
|
|
|
|
will not show any files stored in <I>/tmp</I>,
|
|
but it can show the
|
|
<I>/tmp</I>
|
|
|
|
directory.
|
|
This behavior differs from traditional
|
|
<B>locate</B>
|
|
|
|
implementations.
|
|
<P>
|
|
In some
|
|
<B><A HREF="/cgi-bin/man/man2html?8+updatedb">updatedb</A></B>(8)
|
|
|
|
implementations <B>PRUNEPATHS</B> can be used to exclude non-directory files.
|
|
This is not the case in this implementation.
|
|
<P>
|
|
<B>/etc/updatedb.conf</B>
|
|
|
|
is a shell script in some implementations,
|
|
which allows much more flexibility in defining the variables.
|
|
Equivalent functionality can be achieved by using the command-line options
|
|
to
|
|
<B><A HREF="/cgi-bin/man/man2html?8+updatedb">updatedb</A></B>(8).
