python - Send message to LCD via Command Line argument using Raspberry Pi -


i have piece of code (from adafruit website) write chars lcd. there possibility of doing via command line arguments?

thank in advance.

code:

#!/usr/bin/python  adafruit_charlcd import adafruit_charlcd subprocess import * time import sleep, strftime datetime import datetime  lcd = adafruit_charlcd()  cmd = "ip addr show eth0 | grep inet | awk '{print $2}' | cut -d/ -f1"  lcd.begin(16,1)  def run_cmd(cmd):         p = popen(cmd, shell=true, stdout=pipe)         output = p.communicate()[0]         return output  while 1:         lcd.clear()         ipaddr = run_cmd(cmd)         lcd.message(datetime.now().strftime('%b %d  %h:%m:%s\n'))         lcd.message('ip %s' % ( ipaddr ) )         sleep(2)

the relevant code example is:

#!/usr/bin/python  adafruit_charlcd import adafruit_charlcd lcd = adafruit_charlcd() lcd.begin(16,1) lcd.message(somekindofstring)

...where somekindofstring message. doesn't writing arbitrary hard. if it's more "how know command line arguments are?" aspect, want @ sys.argv (tutorial)
