Synopsis
xxd [options
] [files
]
Similar to od
, xxd
produces a hexadecimal or binary dump of
a file in several different formats. It can also do the reverse,
converting from its hex dump format back into the original data. For
example, here’s a hex dump of binary file /usr/bin/who:
➜ xxd /usr/bin/who
0000000: cafe babe 0000 0002 0100 ... 0003 ................
0000010: 0000 1000 0000 4c60 0000 ... 0007 ......L`........
0000020: 0000 0003 0000 6000 0000 ... 000c ......`...K.....
...
The left column indicates the file offset of the row, the next eight columns contain the data, and the final column displays the printable characters in the row, if any.
By default, xxd
outputs three
columns: file offsets, the data in hex, and the data as text
(printable characters only).
