xfgusta/xdump

Display file contents in hexadecimal and ASCII

xdump

The xdump utility is a filter which displays the specified file, or standard input if no file is specified, in hexadecimal and ASCII format. It uses a colored output to distinguish different categories of bytes.

The categories of bytes are:

• NULL bytes
• printable ASCII characters
• ASCII whitespace characters
• other ASCII characters
• non-ASCII

The colors can be changed with the XDUMP_COLORS environment variable. Its value is a semicolon-separated list that defaults to off=7;bar=7;nul=238;print=7;space=227;ascii=111;nonascii=204. The color must be a valid 8-bit color code.

When the NO_COLOR environment variable is present or when the standard output isn't connected to a terminal, the colored output is disabled.
