Question

I have a data one on each line in a file as below

BMT.PQ
DMZ.IV
VLD.Q
WPS.T

I am looking for a regex to split out into two categories of output

One where starting letter of the data is between A to M

and other

where starting letter of the data is from N to Z

I tried this

[A-M].* for getting first half of data with first beginning letter from A to M

and i was expecting a result/regex text match of

only :

BMT.PQ 
DMZ.PQ

but it also gave a match for

LD.Q which was incorrect for me.

I even unsuccessfully tried [(A-M)(A-M)(A-M)].*

Basically i want to split based on starting letter in the data. One half for data beginning with letters from A to M and second half for data beginning with letter N to Z.

Answer 1

The carat symbol represents the start of the string being searched/matched. The two regexs that you probably need are:

^[A-M]

^[N-Z]
