Only the screen is scrolled (if necessary). Note that the commands zb, zt and zz don't change the position in the file. Zz Place the cursor in the middle line of the screen. Zt Place the cursor in the top line of the screen. Zb Place the cursor in the bottom line of the screen. The selected area is copied to the kill buffer. If a numericĪrgument n is given, n bytes are yanked into the kill buffer. Yank the byte under the cursor into the kill buffer. The same as the x-command, but the bytes deleted are copied to the kill buffer. Note: The bytesĭeleted using the x-command are not copied to the kill buffer. In Visual Mode, the selected area is deleted. If a numeric argument n is given, n bytesĪre deleted. W Move forward to the beginning of a word. If the swapfile can't be created, the undo list is Made to the buffer name are stored in that file, so it is possible to undo (and redo)Īll changes made to the buffer. Swapfile) for each buffer visited (where name is the name of the buffer). Whenever possible hexer creates a file name. U Undo the last change to the current buffer. Note: Moving the cursor (using the arrow keys) If a numeric argument n is given, the replaceĬommand is repeated n times. If an area is selected, allīytes in the selected area are replaced. R Replace a single byte using the Replace Mode. N is given, the kill buffer is pasted n times. Insert the kill buffer at the current position. If a numeric argument n is given, the kill Copy the kill buffer to the current position overwriting theĬontents of the current buffer. N Move to the previous match using the current RE. N Move to the next match using the current RE. Moving the cursor (using the arrow keys) will discard the numeric argument. Numeric argument n is given, the typed text will be inserted n times. I Enter Insert Mode (see below) at the current position of the point. Specified) determines the number rows or columns the cursor will move.ĭifferent from vi: the cursor can be positioned behind the last byte in the The firstīyte in the buffer is at position `0', so the command to move to the beginningĭisplay the buffer name, size, status and the current position at the bottom If noĪrgument is specified, set the position to the end of the buffer. G If a numeric argument n is given, move the cursor to position n. Visually selected area as an argument (see subsection Visual Mode).ī Move backwards to the beginning of a word. With a zero counter wouldn't make sense anyway). To enter a hexadecimal number, type `0x' (this is not a problem, because the x-command To enter an octal number, type a `0' as the first digit. The number will be echoed at the bottom line To enter a numericĪrgument just type the (decimal) number. Some commands in Command Mode can take a numeric argument.
It is not possible to have a command andĪs in vi, there are several editing modes: With a `"'‐character (double quote) are ignored. The editor reads its startup commands from the file ~/.hexerrc (another startup file mayīe specified by setting the environment variable HEXERRC). Note: The long options are not available on all systems. Turn off the usage of the termcap/terminfo ti/te sequence. If commandĬontains spaces, it must be surrounded by double quotes. Start the editing session by executing the editor command command.

Multi buffers, multi level undo, command line editing with completion, binary regularĮxpressions (see below). The most important features of hexer are: Into a buffer (it should work for diskettes). (shouldn't) be used for editing block devices, because it tries to load the whole file DESCRIPTION hexer is a multi-buffer editor for viewing and manipulating binary files.
