Comparing two unsorted files using comm.

literaturedevourer · 10-27-2014, 05:04 AM

Hi all,
I want to compare two unsorted files, file1 and file2 by using comm command in one line.

So far I have tried -
sort file1|comm `sort file2`

or such similar pipe options and have failed. Please help.

There is a bash-specific method:

Code:

comm <(sort file1) <(sort file2)

Have you looked at named pipes?

Code:

mknod A p
mknod B p
sort filea > A &
sort fileb > B &
comm A B
