People started to use the command and found it very useful for report generation and file repair or manipulation.<br><br>The command mimics a C program, with braces '''{ }''' that surround the action to perform based on records from a database file matching either test conditions, regular expressions, etc. Fields numbers appear surprisingly similar to positional parameters (eg. $1, $2, ... etc).<br><br>'''<u>ExampleExamples</u>:'''<br><br>''awk -F";" 'print {$5, $3}' data-file.txt''</li></ul>}}
