KFSCMD(8) KFSCMD(8) NAME kfscmd, ksync - kfs administration SYNOPSIS disk/kfscmd [-n name] cmd ... disk/ksync DESCRIPTION Kfs is a local user-level file server for a Plan 9 terminal with a disk. Kfscmd transmits commands to the kfs server (see kfs(4)). The -n option changes the name of the kfs ser- vice to kfs.name (by default, full name is just kfs). Ksync executes the sync command for all active kfs servers. The known commands are described below. Note that some com- mands are multiple words and should be quoted to appear as a single argument to rc(1). allow Turn permission checking off (to simplify adminis- tration). disallow Turn permission checking on. halt Write all changed blocks and stop the file system. start The opposite of halt; restart the file system. help Print the list of commands. rename file name Change the name of file to name. newuser user Add user to /adm/users and make the standard directories needed for booting. remove file Remove file and place its blocks on the free list. clri file Remove file but do not place the blocks on the free list. This command can be used to remove files that have duplicated blocks. The non- duplicate blocks can be retrieved by checking the file system with option f (see below). create file owner group mode [adl] Create the file. Owner and group are users in /adm/users and mode is an octal number. If Page 1 Plan 9 (printed 11/26/24) KFSCMD(8) KFSCMD(8) present, `a' creates an append only file, `d' cre- ates a directory, and `l' creates a file that is exclusive-use. sync write to disk all of the dirty blocks in the mem- ory cache. stats Report statistics about the performance of the file system. user Re-initialize authentication information by read- ing /adm/users. cfs filsys Change the `console' to the named file system (default is the main system). chat Toggle tracing of 9P messages. check [PRdfprtw] Check the file system. The options are p print the names of directories as they are checked. P print the names of all files as they are checked. r read all of the data blocks and check the tags. f rebuild the list of free blocks. d delete redundant references to a block. t fix bad tags. c fix bad tags and clear the contents of the block. w write all of the blocks that are touched. listen [address] Start a listener to serve the network at address, default il!*!17008. This feature is intended to facilitate small networks of a couple machines in the situation when convenience is more important than performance. This command is only useful on a CPU server, because #c/key needs to be readable. The production file server (see fs(4)) is strongly encouraged for anything more than casual use. noneattach When listening to the network, the default behav- ior is that the user none may only attach over connections that have already authenticated as someone else. This prevents just anyone from being able to dial your server and attach as none. The noneattach command toggles whether none can attach without such a chaperone.
