keeping interpretations for piping?

[Claire Arthur]

Hi all,

I confess I'm a little rusty on my humdrum skills. However, it would be useful in many cases to have the output of a function "keep" or display the exclusive (and possibly local) interpretations.  For instance, given that many of the functions require that the data spine is a valid humdrum spine, if I run hgrep or grep to narrow my results, I may wish to then perform some calculation or function with only those results but I can't do that unless they have interpretations.  I don't see an option on hgrep for keeping these interpretations. Is there a way to do this?  If it helps, I'm doing the following:

$beat -ca somefile.krn | grep '{' > output

#now I want to find the differences along the **absb spine for only the records I extracted, essentially:

$extractx -s $ output | xdelta -s =

However, I obviously can't do that since extractx won't work without spine info.

Am I just rusty and missing something? Thoughts anyone?

 yank -o 'regexp' -r 1 filename

operates like grep while retaining interpretations in the output. Furthermore, adding the -c option will echo all comments in the output.

Thanks David! I forgot about yank & didn't think of it that way.

Cheers,

Claire
