* The parameters $1, $2,$3 … $9 represent the first, second and third to the 9th fields contained within the record.
* Parameters greater than nine requires the value of the parameter to be placed within braces �(for example: ${10},${11},${12}, etc.)���* There are built-in variables that can be used in the awk expression (for example: '''NR''', '''NF''', '''FILENAME''', etc.)
* You can use the '''-F''' option with the awk command to specify the field delimiter.
