beef - flexible Brainfuck interpreter SYNOPSIS
beef [OPTIONS] FILE DESCRIPTION
beef is a Brainfuck interpreter written in C. It is written with flexibility and portability in mind: it is not the smallest nor the fastest Brainfuck interpreter on Earth, but it has some options to control his behavior and doesn't suffer most of the limitations which are usually present in Brainfuck interpreters. One of the best features of beef is that it has no limitations on the length of the tape, which is created dinamically, and allows you to move in any direction, even to move an unlimited amount of cells left when you are on the starting cell. beef also allows you to control his behavior in case it reads and EOF from the input stream: see below for a list of available options. OPTIONS
-d Enable debugging. The debugging command # is not part of the Brainfuck language, but it's an useful feature for the programmer, so most interpreters implement it. Debugging is off by default. -e When read an EOF from input, store an EOF in the current cell. This is for compatibility with programs written for other inter- preters; the default behavior is to store a 0 in the current cell when an EOF is read. -n When read an EOF from input, do nothing. This is the default behavior in some other interpreters, so it's supported in beef for com- patibility reasons. The default behavior is to store a 0 on the current cell instead. --version Show the version number and exit successfully. --help Show a short help message and exit with success. EXIT STATUS
beef returns an exit staus of zero on success, or an exit status of -1 if it was unable to perform the requested operation. Please note that no checks are performed on the code: if the code you are trying to run is buggy, beef will run it anyway and the result will probably differ from what you expected. AUTHOR

THISCELL(5) AFS File Reference THISCELL(5) NAME
ThisCell - Defines the local cell name DESCRIPTION
The ThisCell file defines the local cell name. There are two versions of this file, one for a AFS client and one for an AFS server. Client ThisCell The client version of the ThisCell file defines the complete Internet domain-style name (for example, "abc.com") of the cell to which the local client machine belongs. It must reside in the /etc/openafs directory on every AFS client machine. To change a client machine's cell membership, edit the file and reboot the machine. The file is in ASCII format and contains a character string on a single line. The OpenAFS Quick Start Guide instructs the administrator to create it during the installation of each client machine. The client machine's cell membership determines three defaults important to its functioning: o The cell in which the machine's users authenticate by default. The effect is two-fold: o The AFS-modified login utilities and the klog command interpreter contact an Authentication Server in the cell named in the ThisCell file (unless -cell argument to the klog command specifies an alternate cell). o The command interpreters combine the cell name with the password that the user provides, generating an encryption key from the combination. For authentication to succeed, both the cell name and password must match the ones used to generate the user's encryption key stored in the Authentication Database. o The cell the Cache Manager considers its local, or home, cell. By default, the Cache Manager allows programs that reside in its home cell to run with setuid permission, but not programs from foreign cells. For more details, see the fs getcellstatus and fs setcell reference pages. o Which AFS server processes the local AFS command interpreters contact by default as they execute commands issued on the machine. The client version of the ThisCell file is distinct from the server version, which resides in the /etc/openafs/server directory on each AFS server machine. If a server machine also runs as a client, it is acceptable for the server and client versions of the file on the same machine to name different cells. However, the behavior that results from this configuration can be more confusing than useful. Server ThisCell The server version of the ThisCell file defines the complete Internet domain-style name (for example, "abc.com") of the cell to which the server machine belongs. It must reside in the /etc/openafs/server directory on every AFS server machine. The file is in ASCII format and contains a character string on a single line. The initial version of the file is created with the bos setcellname command during the installation of the cell's first file server machine, and the OpenAFS Quick Start Guide includes instructions for copying it over to additional server machine during their installation. The only reason to edit the file is as part of changing the cell's name, which is strongly discouraged because of the large number of configuration changes involved. In particular, changing the cell name requires rebuilding the entire Authentication Database, because the Authentication Server combines the cell name it finds in this file with each user and server password and converts the combination into an encryption key before recording it in the Database.
