.TH DEBBUGS\-DBHASH 8
.SH NAME
debbugs\-dbhash \- migrate a debbugs database to hashed format
.SH SYNOPSIS
.B debbugs\-dbhash
.I old-db-directory
.I new-db-directory
.SH DESCRIPTION
.B debbugs\-dbhash
converts an old-style flat debbugs database into a new-style
hashed-directory debbugs database, for use with debbugs 2.4 and
above.
.PP
The old database is simply copied, and otherwise left untouched.
The directory given for the new database must not already exist.
.PP
In the hashed format, files with names of the form
.I 1023.log
are now stored as
.I 23/1023.log
instead.
This improves performance on many filesystems for debbugs
installations with large numbers of bug reports.
.SH WARNINGS
.B debbugs\-dbhash
will print a warning message for each file whose name is of a form
that cannot be hashed as above.
Typical debbugs installations will have a few of these, usually
index files and the like.
.SH AUTHORS
Adam Heath is primarily responsible for the hashed directory support
in debbugs.
