Question

Can anybody help me to use awk command from python script in order to parse the data from that file

#!/usr/bin/python3
import os
os.system ([cat mylog2017-10-29.log |grep OCS0 |cut -c1-21 |sort |uniq -c |awk '$1 >500'])
if $1 > 501:
 print ("TPS is High")
else :
  print ("TPS is low")

您将必须通过以下方式重写系统命令调用：

os.system ([cat mylog2017-10-29.log |grep OCS0 |cut -c1-21 |sort |uniq -c | awk '{if($1 > 501)print "TPS is High";else print"TPS is low";}'])
