Thank you I think I got the answer.. I needed 4tty
tty 1: vi Ambuj.txt
tty 2: proc/<pid of vim>/fd showed 1,2,3,4 FD`s
tty 3: vi Ambuj.txt
tty 4: proc/<pid of vim>/fd showed 1,2,3,4 FD`s
Close the vi in tty4
tty3: vi Ambuj*2*.txt
tty4: proc/<pid of vim>/fd showed 1,2,3,3 FD`s
The FDs were different?
Regards,
Ambuj A Thacker
