Thanks for helping out!
Dave you mentioned about false matches in case of string in m is substring of
line. How do I manage that issue? Is there any other method I should look into?
What I am looking to do is..I have a list of m which I need to map in the same
sequence to the ALL_BUSES_FINAL file and get the entire line which has the
string in m.I want to iterate through all the lines in ALL_BUSES_FINAL to match
the all strings in m.
