Unix-Wizards and Info-Unix were so helpful on my last query, I thought I'd
throw this one out, too. (I'm still taking responses to that query
regarding the purchase of a Gould, Pyramid, Celerity, or VAX!)
My organization has need of a program which will scan a text file
(presumably a reference work, a journal paper, a manual, documents, stuff
like that) and produce an output listing giving, for each word in the
input file, the location (line number and input file name) and surrounding
context of the word (like the preceding and succeeding 1-10 words).
Location should include input file name so that I could invoke the
program with a command like "invert *.txt" and identify in which file
each listed reference is found.
The "ptx" program (comes with System V and other Unices, I think) comes
close, but no cigar. It quite often picks up multi-word phrases as
keywords. It doesn't give the user the degree of control over keyword
and context selection that we need. So "ptx" is out the window.
We can of course write the software ourselves, but (you know the story)
if it's already out there somewhere...
Thanks in advance for any leads you can provide.

I disclaim everything anybody ever said about anything.
