As described in <STRONG><A HREF="term.5.html">term(5)</A></STRONG>, the database may be either a
directory tree (one file per terminal entry) or a hashed

+ only one type of entry, depending on how it was built:
<STRONG>o</STRONG> For directory trees, the top-level directory, e.g.,
/usr/share/terminfo, specifies the location of the
as the default directory name (only adding a ".db"
suffix).
- The results are normally placed in the system terminfo
- database <STRONG>/usr/share/terminfo</STRONG>. The compiled terminal
- description can be placed in a different terminfo
- database. There are two ways to achieve this:
+ In either case (directory or hashed database), <STRONG>tic</STRONG> will

+ tory, this would be the "terminfo" leaf, versus a "ter-

- <STRONG>o</STRONG> First, you may override the system default by setting
- the variable <STRONG>TERMINFO</STRONG> in your shell environment to a
- valid database location, e.g., an existing directory
- (for directory trees) or valid location for a hashed

+ using the <STRONG>-o</STRONG> option, or by setting the variable <STRONG>TER-</STRONG>

+ location.
<STRONG>o</STRONG> Secondly, if <STRONG>tic</STRONG> cannot write in <EM>/usr/share/terminfo</EM>
or the location specified using your TERMINFO vari-
exists, the entry is placed there.
Libraries that read terminfo entries are expected to check
- for a location specified with the TERMINFO variable first,
- look at <EM>$HOME/.terminfo</EM> if TERMINFO is not set, and
- finally look in <EM>/usr/share/terminfo</EM>.
