sed/awk/perl: How to replace all spaces each with an underscore that occur before a specific string ?
I really prefer a sed one liner. Example Input : This is my book. It is too thick to read. The author gets little royalty but the publisher makes a lot. Output: This_is_my_book._It_is_too__thick_to read. The author gets little royalty but the publisher makes a lot. We replaced all the spaces with underscores before the first occurence of the string "to ". Thanks Gnuist -- http://mail.python.org/mailman/listinfo/python-list
