![]() Select the way the program will get his size, the three available options are:Īsk kernel This option will use Linux kernel ioctls to get the size of the device. Get the size of a device, each time you change the read-only flag, open or refresh the size of a device, vche will pop up a menu where you have to Viewing DevicesĪs with regular files you can also view or edit devices. Edit mode TAB KEY Switch beetwen HEX and ASCII editing.į3 Set the edit mask (needed for XOR, OR and AND operations).į8 Add 1 to the byte at the cursor position. HOME KEY Go to the beginning of the file. g, F6 Seek to an offset (to enter an hexadecimal offset you must prefix it with a "0x").į8 Shows you the ascii table (as found in character ROM), shows also in hex, octal, decimal and binary.į9 Shows GNU GPL (General Public License). R Refresh file size, use it if the size of the file changes during viewing, by any reason. It is also useful when viewing files or devices R Redraw the screen, it is needed when other process writes to the current tty and the screen gets corrupted. (Prefix a "0x" to enter the string in hexadecimal). S, F4 Search a string taking care of case. The keys have different meanings if you are in view or edit mode:į7 Select another file manually from the file list given at the command line. ![]() You could also press F7 to browse the list ofįiles and select one manually, moving with the arrow keys.Ĭommands c-c Control-C, kills the program. Them easily using the commands: n to go to the next file and p to go to the previous file. If you provided more than one filename at the command line, you could view or edit any of You could enter the edit mask as a decimal or as hex number, prefixing a "0x" to it (like in C). NEG Negates the bytes at cursor position.ĪDD and SUB Adds or substract 1 from the bytes you want. XOR Do a XOR on the byte at cursor position with the value set in the edit mask. If you want, for example, to XOR some bytes, the value used to XOR that bytes is the edit mask. When you are in edit mode you can press F3 to set the edit mask. There are six flags, each one shows the current program state and the behavior vche will have. Sequences, for more information see the console_codes(4) man page. Vche-raw It is the Run AnyWhere version (or RAW version, his name is twofold), it does all the screen I/O using the linux console escape and control ![]() Vche-nc It is the NCURSES version, it will use that library to do all the screen I/O, so it will not show non-printable ASCII. So this version will run only on Linux on a local console, and It uses the /dev/vcs and /dev/vcsa character devices to do all it's screen I/O. ![]() Vche is a hex editor and viewer which lets you see all the 256 characters, as found in ![]()
