Issue
I have 2 txt files in Linux.
A.txt contents (each line will contain a number):
1
2
3
B.txt contents (each line will contain a number):
1
2
3
10
20
30
grep -f A.txt B.txt
results below:
1
2
3
10
20
30
Is there a way to grep in such a way I will get only the exact match, i.e. not 10, 20, 30?
Thanks in advance
Solution
For exact match use -x
switch
grep -x -f A.txt B.txt
EDIT: If you don't want grep's regex capabilities and need to treat search pattern as fixed-strings then use -F
switch as:
grep -xF -f A.txt B.txt
