# beav(1)

binary file editor and viewer

## NAME

beav - binary file editor and viewer

## SYNOPSIS

**beav** \[file...\]

## DESCRIPTION

This is a brief description of the minimal set of commands that are necessary to start using *beav* effectively. For more information, review the file /usr/share/doc/beav/beav140.txt.gz.

The *file-visit* command, **Ctl-X Ctl-V**, can be used to read a file in for editing.   The file can also be read in from the command line; **beav \<edit\_file\>**.

Data is displayed in one or more windows. These commands can be used to navigate around the windows.

*move-back-char*      **Ctl-B     moves left**\
 *move-back-line*      **Ctl-P     moves up**\
 *move-forw-char*      **Ctl-F     moves right**\
 *move-forw-line*      **Ctl-N     moves down**\
 *window-delete*       **Ctl-X 0   delete window**\
 *window-expand*       **Ctl-X 1   expand window**\

The *move-to-byte* command, **Ctl-X G**, will prompt you for a byte position to move to.

These commands will insert a zero byte at the cursor position or delete the byte at that position.

*insert-unit*         **Ctl-X I**\
 *delete-forw-unit*    **Esc D**\

The *file-save* command, **Ctl-X Ctl-S**, will save the data to the file if a change has been made.

The *help* command, **Esc ?**, will display a list of all commands and their current key bindings.

The *abort-cmd* command, **Ctl-G**, will abort any command that is in operation.

The *quit-no-save* command, **Ctl-X Ctl-C**, will exit beav. If there is any data that has not been saved you will be warned.
