.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. Colin Watson wrote .B debbugs\-dbhash and this man page.
