UPDATEDB(1) General Commands Manual UPDATEDB(1) NAME updatedb - update a file name database SYNOPSIS updatedb [options] DESCRIPTION This manual page documents the GNU version of updatedb, which updates file name databases used by GNU locate. The file name databases contain lists of files that were in particular directory trees when the databases were last updated. The file name of the default database is determined when lo- cate and updatedb are configured and installed. The frequency with which the databases are updated and the directories for which they contain en- tries depend on how often updatedb is run, and with which arguments. In networked environments, it often makes sense to build a database at the root of each filesystem, containing the entries for that filesystem. up- datedb is then run for each filesystem on the fileserver where that filesystem is on a local disk, to prevent thrashing the network. Users can select which databases locate searches using an environment variable or command line option; see locate(1). Databases cannot be concatenated to- gether. The LOCATE02 database format was introduced in GNU findutils version 4.0 in order to allow machines with different byte orderings to share the data- bases. GNU locate can read both the old and LOCATE02 database formats, though support for the old pre-4.0 database format will be removed shortly. OPTIONS --findoptions='-option1 -option2...' Global options to pass on to find. The environment variable FINDOP- TIONS also sets this value. Default is none. --localpaths='path1 path2...' Non-network directories to put in the database. Default is /. --netpaths='path1 path2...' Network (NFS, AFS, RFS, etc.) directories to put in the database. The environment variable NETPATHS also sets this value. Default is none. --prunepaths='path1 path2...' Directories to not put in the database, which would otherwise be. Remove any trailing slashes from the path names, otherwise updatedb won't recognise the paths you want to omit (because it uses them as regular expression patterns). The environment variable PRUNEPATHS also sets this value. Default is /tmp /usr/tmp /var/tmp /afs. --prunefs='path...' File systems to not put in the database, which would otherwise be. Note that files are pruned when a file system is reached; any file system mounted under an undesired file system will be ignored. The environment variable PRUNEFS also sets this value. Default is nfs NFS proc. --output=dbfile The database file to build. Default is system-dependent. In Debian GNU/Linux, the default is /var/cache/locate/locatedb. --localuser=user The user to search non-network directories as, using su(1). Default is to search the non-network directories as the current user. You can also use the environment variable LOCALUSER to set this user. --netuser=user The user to search network directories as, using su(1). Default is daemon. You can also use the environment variable NETUSER to set this user. --dbformat=F Create the database in format F. The default format is called LO- CATE02. Alternatively the slocate format is also supported. When the slocate format is in use, the database produced is marked as having security level 1. If you want to build a system-wide slocate database, you may want to run updatedb as root. --version Print the version number of updatedb and exit. --help Print a summary of the options to updatedb and exit. BUGS The updatedb program correctly handles filenames containing newlines, but only if the system's sort command has a working -z option. If you suspect that locate may need to return filenames containing newlines, consider us- ing its --null option.
