Script to replace contents inside the files

[Kunal Jamdade]

I have thousands of html files inside a folder. I want to replace the
filename present inside another files. Say for ex:- fileName :-
'abcd1234.html' is found inside another file say file2.html. Then I want to
remove the last 4 digits of the fileName i.e,. 'abcd1234.html' =>
'abcd.htm'.

I have tried a script . But your suggestions upon the script are welcomed.

Regards,
Kunal
