It's not specific to bash but you can use tput cup Y X to set the cursor position:

tput sc         # save cursor position
tput cup 10 0
echo -n "hello"
tput rc         # restore cursor position

Yo can try to show line numbers of the files, and grep it for the line:

$ cat test 
A
B
C
$ cat test -n |grep ^"     2"
     2  B

$ cat test2
A
B
C
D
E
F
$ cat test2 -n |grep ^"     4"
     4  D
