Looking at files and partitions as is

RByte is a hexadecimal viewer for files and partitions. It is based on GTK+ and runs on Linux.

For displaying partitions (as well as files, of course), the program must have the read permission.

The size of a file or a partition to be displayed is unlimited.

Bytes can be interpreted in different way and processed for different purpose. For this reason, RByte offers four methods for copying selected bytes to the clipboard.

The table below shows what content will be placed into the clipboard, when three bytes with values 0x41, 0x42 and 0x43 have been copied.

The program consists of one file and runs out of the box.

If you want that RByte saves settings, create an empty file rbyte.conf and save it either in the directory where the program file is saved, or in the following location: ~/.config/rbyte/rbyte.conf. Here, the tilde symbol means the home directory, e.g.: /home/andrew/.config/rbyte/rbyte.conf.
