The command "xxd -l ${32} ${input_file}" is used to create a hexadecimal dump of the specified file. Here's a breakdown of each component:
- "xxd" is the command-line utility used for creating the hexadecimal dump.
- "-l" is an option that specifies the length of data to be read from the input file.
- "${32}" is a placeholder for a variable holding the value 32. This determines the number of bytes to be read from the input file.
- "${input_file}" is another placeholder for a variable that represents the input file. This should be replaced with the actual file name or path.
In summary, the command will generate a hexadecimal dump of the input file, reading the first 32 bytes of data.
