NAME

bos_prune - Removes obsolete files from /usr/libexec/yfs and /var/log/yfs

SYNOPSIS

bos prune -server <machine name> [-bak] [-old] [-core] [-all] [-cell <cell name>] [-noauth] [-localauth] [-principal <authentication principal> [-encrypt [<yes|no>]] [-config <configuration file>] [-help]

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:

(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/libexec/yfs directory that have a .BAK extension. Do not combine this flag and the -all flag.

-old

Removes all files from the /usr/libexec/yfs directory that have a .OLD extension. Do not combine this flag and the -all flag.

-core

Removes all files from the /var/log/yfs 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/yfs/server/KeyFileExt 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).

-principal <authentication principal>

Indicates the principal to be used for authentication. This option can be useful when several credentials caches are available for different principals.

-encrypt [<yes|no>]

Enables or disables encryption for the command so that the operation's results are not transmitted across the network in clear text.

-config <configuration file>

Sets the location of the configuration file to be used. The default file is /etc/yfs/yfs-client.conf.

-help

Prints the online help for this command. All other valid options are ignored.

EXAMPLES

The following example removes all files from the /usr/libexec/yfs directory on the machine fs3.example.com that have a .BAK or .OLD extension.

   % bos prune -server fs3.example.com -bak -old

The following example removes all files from the /usr/libexec/yfs directory on the machine db2.example.com that have a .BAK or .OLD extension, and all files from the /var/log/yfs directory that have a core. prefix.

   % bos prune -server db2.example.com -all

PRIVILEGE REQUIRED

The issuer must be listed in the /etc/yfs/server/UserListExt file on the machine named by the -server argument, or must be logged onto a server with an account capable of reading the /etc/yfs/server/KeyFileExt file if the -localauth flag is included.

The bos prune command cannot be run against servers which are in restricted mode.
