bos_prune
BOS_PRUNE(8) AFS Command Reference BOS_PRUNE(8)NAME
bos_prune - Removes obsolete files from /usr/lib/openafs and /var/log/openafs
SYNOPSIS
bos prune -server <machine name> [-bak] [-old] [-core]
[-all] [-cell <cell name>] [-noauth] [-localauth]
[-help]
bos p -s <machine name> [-b] [-o] [-co] [-a]
[-ce <cell name>] [-n] [-l] [-h]
DESCRIPTION
The bos prune command removes files from the local disk of the server machine named by the -server argument, as specified by one or more of
the following flags provided on the command line:
o The -bak flag removes all files from the /usr/lib/openafs directory that have a ".BAK" extension.
o The -old flag removes all files from the /usr/lib/openafs directory that have a ".OLD" extension.
o The -core flag removes all files from the /var/log/openafs directory that have a "core." prefix.
o The -all flag removes all three types of files at once.
(If none of these flags are included, the command appears to succeed, but removes no files at all.)
To display the timestamp on the current, ".BAK", and ".OLD" versions of one or more files, use the bos getdate command.
OPTIONS -server <machine name>
Indicates the server machine from which to remove files. Identify the machine by IP address or its host name (either fully-qualified or
abbreviated unambiguously). For details, see bos(8).
-bak
Removes all files from the /usr/lib/openafs directory that have a ".BAK" extension. Do not combine this flag and the -all flag.
-old
Removes all files from the /usr/lib/openafs directory that have a ".OLD" extension. Do not combine this flag and the -all flag.
-core
Removes all files from the /var/log/openafs directory that have a "core." prefix. Do not combine this flag and the -all flag.
-all
Combines the effect of the -bak, -old, and -core flags. Do not combine this flag with any of those three.
-cell <cell name>
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see bos(8).
-noauth
Assigns the unprivileged identity "anonymous" to the issuer. Do not combine this flag with the -localauth flag. For more details, see
bos(8).
-localauth
Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The bos command interpreter presents the ticket
to the BOS Server during mutual authentication. Do not combine this flag with the -cell or -noauth options. For more details, see
bos(8).
-help
Prints the online help for this command. All other valid options are ignored.
EXAMPLES
The following example removes all files from the /usr/lib/openafs directory on the machine "fs3.abc.com" that have a ".BAK" or ".OLD"
extension.
% bos prune -server fs3.abc.com -bak -old
The following example removes all files from the /usr/lib/openafs directory on the machine "db2.abc.com" that have a ".BAK" or ".OLD"
extension, and all files from the /var/log/openafs directory that have a "core." prefix.
% bos prune -server db2.abc.com -all
PRIVILEGE REQUIRED
The issuer must be listed in the /etc/openafs/server/UserList file on the machine named by the -server argument, or must be logged onto a
server machine as the local superuser "root" if the -localauth flag is included.
The bos prune command cannot be run against servers which are in restricted mode.
