Hi Nivas,

Can you explain the problem in detail.

Based on what criteria you want the output?

Regards,

you want a command that 'show me all the machine lines that are in this list of files?'

Code:
$ cat >one
a
b
c
1
2
3
^d

$ cat >two
a
b
c
d
e
f
g
^d

$ comm -12 one two
a
b
c

Sure, I realize you got an extra 'a' that I didn't attempt. Good deal.
