Hi
I need a perl program which will substitute all occurrence of 'wood' of a file (say data.txt) by 'food'.
The word 'wood' may occur anywhere in the file, beginning of a line, in the middle or anywhere.
I need a file operation only, the program should open the file data.txt, make the substitution and save the changes.
I do not want any inline editing (perl -i )
