ixpc

IXPC(1) 						      General Commands Manual							   IXPC(1)

NAME

       ixpc - ixp client

SYNOPSIS

       ixpc [-a address] action file
       ixpc -v

DESCRIPTION

   Overview
       ixpc is a client to access a 9P file server from the command line or from shell scripts. It can be used to configure wmii(1).

   Options
       -a address
	      Lets you specify the address to which ixpc will establish a connection. If this option is not supplied, and the environment variable
	      IXP_ADDRESS is set, ixpc will use this value as its address. Currently, the address can only be a unix socket file or a tcp  socket.
	      The  syntax  for	address  is  taken  (along  with  many	other  profound  ideas)  from the Plan 9 operating system and has the form
	      unix!/path/to/socket for unix socket files, and tcp!hostname!port for tcp sockets.

       -v     Prints version information to stdout, then exits.

       The syntax of the actions is as follows:

       write  Writes the supplied data from the standard input to file, overwriting any previous data.	The data to be written	is  arbitrary  and
	      only gains meaning (and restrictions) when it is interpreted by wmiiwm(1).  See EXAMPLES below.

       xwrite The same as write, but the data is taken from subsequent arguments, rather than the standard input.

       create Creates file or directory. If the file exists, nothing is done.

       ls     Lists files and directories.

       read   Reads file or directory contents.

       remove Removes file or directory tree.

ENVIRONMENT

       IXP_ADDRESS
	      See above.

EXAMPLES

       ixpc ls /
	      This  prints the root directory of the wmii filesystem, if IXP_ADDRESS is set to the address of wmii. For more information about the
	      contents of this filesystem, see wmiiwm(1).

       ixpc xwrite /ctl quit
	      Write 'quit' to the main control file of the wmii filesystem, effectively leaving wmii.

       ixpc write /keys < keys.txt
	      Replace the contents of /keys with the contents of keys.txt
