fb 1.5 - Binary File Viewer, Editor, and Manipulator '''Author:''' John Howard Swaby '''Homepage:''' http://home.mho.net/jswaby/fb.html '''Family:''' HexEditorFamily '''Platform:''' Windows, Gnu/Linux, Others '''License:''' Open Source fb is a utility for the viewing and editing of binary files. Files can be viewed in binary, decimal, hexadecimal, and octal, and/or characters. In addition to simple overwriting, a binary file may be dumped as binary, hexadecimal, decimal, or octal numbers; edited with one's favorite text editor; and then translated back into a binary file. fb also has methods for appending and copying sections of a file, replacing sections of a file with a particular value, and a method for comparing files: showing differences in either binary, decimal, hexadecimal, or octal. '''Screenshot:''' A page similar to the one below can be dumped to the screen by invoking fb in either of these two ways: '''fb -r 483.691 -ds -p .13 File''' - or - '''fb -r 483.691 -dt -p .13 - < File''' [ 0 1 2 3 4 5 6 7 8 9 10 11 12 0123456789012] 483: 084 104 101 032 032 102 105 108 101 032 032 099 097 |The file ca| 496: 110 032 098 101 032 118 105 101 119 101 100 032 105 |n be viewed i| 509: 110 032 098 105 110 097 114 121 044 032 111 099 116 |n binary, oct| 522: 097 108 044 010 032 032 032 032 032 032 032 100 101 |al,. de| 535: 099 105 109 097 108 044 032 104 101 120 097 100 101 |cimal, hexade| 548: 099 105 109 097 108 044 032 111 114 032 099 104 097 |cimal, or cha| 561: 114 097 099 116 101 114 115 046 032 032 079 112 116 |racters.
