Read in CLI argumnet, then use regex's to look for it. -Python

Question

Hello all! Sorry if this is probably a simple fix but I can't think of one. I am trying to take a command line argument (in this case a name) and search through a file hierarchy and keep track of the number of times that name comes up. I was just wondering how to store the CL input and then search through files using a regular expression with that input as my search key.

Answer 1

import sys
import os
the_name= sys.argv[1]
count=0
for r,d,f in os.walk("/mypath"):
    for file in f:
        if the_name in file:
            count+=1

If you want to search IN the file themselves,

for r,d,f in os.walk("/mypath"):
    for file in f:
        for line in open(os.path.join(r,file)) :
            if the_name in line:  
                count+=line.count(the_name)
