X11/bdftopcf(1) -- convert X font from Bitmap Distribution Format to Portable Compiled Format
|
|
Bdftopcf is a font compiler for the X server and font server. Fonts in Portable Compiled Format can be read by any architecture, although the file is structured to allow one particular architecture to read them directly without reformatting. This allows fast reading on the appropriate machine, but the files are still portable (but read more slowly) on other machines. |

bdiff(1) -- big diff
|
|
bdiff is used in a manner analogous to diff to find which lines in file1 and file2 must be changed to bring the files into agreement. Its purpose is to allow processing of files too large for diff. If file1 (file2) is -, the standard input is read. Valid options to bdiff are: n The number of line segments. The value of n is 3500 by default. If the optional third argument is given and it is numeric, it is used as the value for n. This is us... |

bfs(1) -- big file scanner
|
|
The bfs command is similar to ed except that it is read-only and processes much larger files. Files can be up to 1024K bytes and 32K lines, with up to 512 bytes, including new-line, per line (255 for 16-bit machines). bfs is usually more efficient than ed for scanning a file, since the file is not copied to a buffer. It is most useful for identifying sections of a large file where the csplit command can be used to divide it into more manageable pie... |

bg(1) -- run jobs in the background
|
|
If job control is enabled (see the description of set -m in the sh(1) manpage), the bg utility resumes suspended jobs from the current environment by running them as background jobs. If the job specified by job_id is already a running background job, the bg utility has no effect and will exit successfully. Using bg to place a job into the background causes its process ID to become "known in the current shell execution environment", as if it had been started as an asynchronous list.... |

bgicons(1) -- maintain icons on the desktop background
|
|
bgicons maintains icons on the desktop background by comparing its notion of the system stored in icondb with the new state of the system from inputfile. If the -inputfile argument is not specified, the new state of the system is read from standard input. inputfile is a text file containing lines of serialized DNA. icondb is maintained by bgicons; the first time bgicons is run for a particular icondb, it is expected that icondb will not exist. icondb should not be edited by any program other tha... |

bindkey(1) -- function key binding facility for use with xwsh(1G)
|
|
bindkey is a program which provides an interface to the xwsh(1G) function key binding facilities. key is the name of a key on the keyboard; type bindkey without arguments to obtain a list of valid keys. The following are valid bindkey keys: f1 f2 f3 f4 f5 f6 f7 f8 f9 f10 f11 f12 print-scrn scroll-lock pause insert home page-up end page-down left-arrow up-arrow down-arrow right-arrow binding is the text string which the key is bound to. The text of the binding argument must be in the printable ch... |

bison(1) -- GNU Project parser generator (yacc replacement)
|
|
Bison is a parser generator in the style of yacc(1). It should be upwardly compatible with input files designed for yacc. Input files should follow the yacc convention of ending in .y. Unlike yacc, the generated files do not have fixed names, but instead use the prefix of the input file. For instance, a grammar description file named parse.y would produce the generated parser in a file named parse.tab.c, instead of yacc's y.tab.c. This description of the options that can be given to bison is ad... |

X11/bitmap(1) -- bitmap editor and converter utilities for the X Window System
|
|
The bitmap program is a rudimentary tool for creating or editing rectangular images made up of 1's and 0's. Bitmaps are used in X for defining clipping regions, cursor shapes, icon shapes, and tile and stipple patterns. The bmtoa and atobm filters convert bitmap files (FILE FORMAT) to and from ASCII strings. They are most commonly used to quickly print out bitmaps and to generate versions for including in text.... |

bootp(1) -- server for Internet Bootstrap Protocol
|
|
bootp is a server that supports the Internet Bootstrap Protocol (BOOTP). This protocol is designed to allow a (possibly diskless) client machine to determine its own Internet address, the address of a boot server, and the name of an appropriate boot file to be loaded and executed. BOOTP does not provide the actual transfer of the boot file, which is typically done with a simple file transfer protocol such as TFTP. A detailed protocol specification for BOOTP is contained in RFC 951, which is avai... |

bootpadd(1) -- add client system to bootptab
|
|
bootpadd is a tool to help automate the process of adding client hosts to /usr/etc/bootptab. See bootp(1M) for more details on the contents and format of /usr/etc/bootptab. bootpadd can also be used to update existing information in the /usr/etc/bootptab. bootpadd checks the /usr/etc/bootptab to see if an entry already exists for the specified host. If an entry exists, the current options are used as defaults. The bootpadd command takes the following arguments: -b bootfile Specifies the name of ... |
|
bootparamd(1) -- boot parameter server
|
|
bootparamd is a server process that provides information to diskless clients necessary for booting. It consults the bootparams database. If the client is not found there, or if the network information service (NIS) is not running, then the /etc/bootparams file is consulted. bootparamd can be invoked either by inetd(1M) or by the user. |
|
brc(1) -- system initialization procedures
|
|
These shell procedures are executed via entries in /etc/inittab by init(1M) whenever the system is booted (or rebooted). First, the bcheckrc procedure checks the status of the root filesystem. If the root filesystem is found to be bad, bcheckrc repairs it. Then, the brc procedure clears the mounted filesystem table, /etc/mtab, and puts the entry for the root filesystem into the mount table. After these two procedures have executed, init checks for the initdefault value in /etc/inittab. This tell... |

bru(1) -- backup and restore utility
|
|
Bru is a UNIX filesystem backup utility with significant enhancements over other more common utilities such as tar, cpio, volcopy, and dd. Some of bru's capabilities include: o Full or incremental backup with quick and easy restoration of files. o Multiple physical volumes per archive. o Data integrity assurance via checksum computation on every archive block. o Ability to properly save and restore directories, symbolic links, block special files, and character special files. o Comparison of ar... |

bsh(1) -- shell, the standard/job control command programming language
|
|
Note: This is the Bourne shell description. All references to sh and shell pertain to bsh and all references below to /usr/lib/rsh, the restricted shell, no longer apply to the Bourne shell. (See sh(1)). bsh is a command programming language that executes commands read from a terminal or a file. jsh is an interface to the shell that provides all the functionality of sh and enables Job Control (see Job Control below). See Invocation below for the meaning of arguments to the shell. ... |
|
bstream(1) -- many buffered filter
|
|
This command is a filter which buffers input from the input file and writes it to the output file. The command is especially useful for reading from or writing to streaming tape drives, where bstream can be used as a speed matching program to keep the tape streaming as much as possible. If input or output files are not specified, then bstream simply copies the standard input to the standard output through multiple buffers. A tape can be written to or read from in this manner, but bstream will no... |
