You can specify a name,also some names. If the names is more one,you can use comma as separator. Example: AdapterMoniter.py-f eth0 AdapterMoniter.py-f eth0,eth2-i specify an interval time to display,defaul 1 second. Unit: second-n to display how many times you want.Default: None,means unlimited number. Example: AdapterMoniter.py-n 2-a to display what action you want,IN/OUT/ALL.Defaul: all. Example: AdapterMoniter.py-an in-s to display the netflow size.Default: B (bytes) values: B (bytes) / k (KB) / m (MB) Example: AdapterMoniter.py-s k EXAMPLE: AdapterMoniter.py-f eth0-I 2-n 10-an in-s k "") if _ _ Name__ = "_ _ main__": num=1 # counter Record the number of exits of the current parameter subscript exitnum=0 # when exiting # get the parameter if len (sys.argv) > 1: # to determine whether there is a parameter input while num
