Compare two files

b5fnpct · #1 (**permalink**) 08-15-2001

Hi,

There are two files with some lines are exactly the same, some lines are not. I want to compare these two files and create a third file contains both the first and second file's lines without duplicate line. Which command should I use? If I write a shell script, what is the syntax to "open" a file instead of using "cat"?

Thanks in advance!

Code:

cat file1 file2 | sort | uniq > file3

Gotta slap myself with a UUOC for that one.

Better solution:

Code:

sort file1 file2 | uniq > file3
