od:tldr:f67f6
The command:
od --format=${x1} --width=${4} -v ${filename}
is used to display the contents of a file in various formats. Let's break down each part of the command:
-
od
: This is the command itself, which stands for "octal dump". It is commonly used to view or manipulate file contents in different formats. -
--format=${x1}
: This option specifies the format in which the file contents should be displayed. In this case,${x1}
is a variable that represents a single hexadecimal number (one byte). So, the file contents will be shown as a sequence of hexadecimal numbers. -
--width=${4}
: This option specifies the number of bytes per line to be displayed.${4}
is a variable representing the number 4, so the contents of the file will be displayed in lines of 4 bytes each. This makes it easier to read and analyze the output. -
-v
: This option stands for "verbose" and it displays additional information along with the file contents. It typically shows the offset and the ASCII representation of each byte. -
${filename}
: This is the variable that represents the name of the file you want to examine. You need to replace${filename}
with the actual name or path of the file you want to inspect.
Overall, the command od --format=${x1} --width=${4} -v ${filename}
will display the contents of the specified file in hexadecimal format, showing lines with 4 bytes each, along with additional details like offset and ASCII representation of the bytes.
