man lsof

Usage example:

   stefan:~$ lsof /dev/pts/2
   COMMAND  PID   USER   FD   TYPE DEVICE SIZE NODE NAME
   bash     353 stefan    0u   CHR  136,2         4 /dev/pts/2
   bash     353 stefan    1u   CHR  136,2         4 /dev/pts/2
   bash     353 stefan    2u   CHR  136,2         4 /dev/pts/2
   bash     353 stefan  255u   CHR  136,2         4 /dev/pts/2
   mutt    2982 stefan    0u   CHR  136,2         4 /dev/pts/2
   mutt    2982 stefan    1u   CHR  136,2         4 /dev/pts/2
   mutt    2982 stefan    2u   CHR  136,2         4 /dev/pts/2
   editor  2988 stefan    0u   CHR  136,2         4 /dev/pts/2
   editor  2988 stefan    1u   CHR  136,2         4 /dev/pts/2
   editor  2988 stefan    2u   CHR  136,2         4 /dev/pts/2

(in the `lsof' package if you don't have it.)
