NAME
hexyl - a command-line hex viewer
SYNOPSIS
hexyl [OPTIONS] [FILE]
DESCRIPTION
hexyl is a simple hex viewer for the terminal. It uses a colored output to distinguish different categories of bytes (NULL bytes, printable ASCII characters, ASCII whitespace characters, other ASCII characters and non-ASCII).
POSITIONAL ARGUMENTS
- FILE
- The file to display. If no FILE argument is given, read from STDIN.
OPTIONS
- -n, --length N
- Only read N bytes from the input. The N argument can also include a unit with a decimal prefix (kB, MB, ..) or binary prefix (kiB, MiB, ..), or can be specified using a hex number.
- Examples:
- Read the first 64 bytes:
- $ hexyl --length=64
- Read the first 4 kibibytes:
- $ hexyl --length=4KiB
- Read the first 255 bytes (specified using a hex number):
- $ hexyl --length=0xff
- -c, --bytes N
- An alias for -n/--length.
- -l N
- Yet another alias for -n/--length.
- -s, --skip N
- Skip the first N bytes of the input. The N argument can also include a unit (see --length for details). A negative value is valid and will seek from the end of the file.
- --block-size SIZE
- Sets the size of the block unit to SIZE (default is 512).
- Examples:
- Sets the block size to 1024 bytes:
- $ hexyl --block-size=1024 --length=5block
- Sets the block size to 4 kilobytes:
- $ hexyl --block-size=4kB --length=2block
- -v, --no-squeezing
- Displays all input data. Otherwise any number of groups of output lines which would be identical to the preceding group of lines, are replaced with a line comprised of a single asterisk.
- --color WHEN
- When to use colors. The auto-mode only displays colors if the output goes to an interactive terminal.
- •
- always (default)
- •
- auto
- •
- never
- --border STYLE
- Whether to draw a border with Unicode characters, ASCII characters, or none at all.
- •
- unicode (default)
- •
- ascii
- •
- none
- -o, --display-offset N
- Add N bytes to the displayed file position. The N argument can also include a unit (see --length for details). A negative value is valid and calculates an offset relative to the end of the file.
- -h, --help
- Prints help information.
- -V, --version
- Prints version information.
NOTES
