Question

How do we compare files?

Senario:
file1 stores 2 groups of data, agf1 and bgf1, say.
file2 stores 2 groups of data, agf2 and bgf2, likewise.
I amended agf1 and bgf2. After comparing the two files and finding that they are different, how do we merge them?
# 2  
have you tried teh command comm?

comm -1,2,3 file1 file2

or you can try the diff command.
# 3  
Question merge done?

Thx Optimus, but how do merge the 2 files though?
# 4  
to merge file1 and file2 into file3
Code:
cat file1 file2 > file3
