Re: [bug-gawk] how to close pipe?

[Davide Brini]

(sorry for the top posting)

cmd = "grep \"" $1 "\" fn.txt"; cmd | getline var; close(cmd)

But that's really just about the most terrible way of doing whatever you're trying to there (and you're still missing posssible multi-line output from grep). It's very likely that the whole task is solvable entirely with awk alone.

After a while I get a too many files open message, how do I close the pipes?
