bytes at for bytes

Get bytes defined by a range. Note that the start is included but the end is excluded, and that the first byte is index 0.

Signature

> bytes at (range) ...rest

Parameters

• range: the indexes to get bytes
• ...rest: for a data structure input, get bytes from data at the given cell paths

Examples

Get a subbytes 0x[10 01] from the bytes 0x[33 44 55 10 01 13]

>  0x[33 44 55 10 01 13] | bytes at [3 4]
Length: 1 (0x1) bytes | printable whitespace ascii_other non_ascii
00000000:   10                                                   •

Alternatively, you can use the form

>  0x[33 44 55 10 01 13] | bytes at '3,4'
Length: 1 (0x1) bytes | printable whitespace ascii_other non_ascii
00000000:   10                                                   •

Drop the last n characters from the string

>  0x[33 44 55 10 01 13] | bytes at ',-3'
Length: 3 (0x3) bytes | printable whitespace ascii_other non_ascii
00000000:   33 44 55                                             3DU

Get the remaining characters from a starting index

>  0x[33 44 55 10 01 13] | bytes at '3,'
Length: 3 (0x3) bytes | printable whitespace ascii_other non_ascii
00000000:   10 01 13                                             •••

Get the characters from the beginning until ending index

>  0x[33 44 55 10 01 13] | bytes at ',4'
Length: 4 (0x4) bytes | printable whitespace ascii_other non_ascii
00000000:   33 44 55 10                                          3DU•

Or the characters from the beginning until ending index inside a table

>  [[ColA ColB ColC]; [0x[11 12 13] 0x[14 15 16] 0x[17 18 19]]] | bytes at "1," ColB ColC
