Dear Unix-experts, with the following simple script:
#!/bin/sh cat index.idx | sort > index.ind I sort the contents of a file and write it in another file. Now, I want that a small vertical space, i.e. an empty line or two, were inserted before all the words that start with a new letter. It's clear that I'm working at some indexing mechanism. Please suggest whoever can what code should I add to that one above in order to do what I want. Thanks in advance for any help, Rodolfo
