Re: How to combine lines into paragraphs?

[Peng Yu]

Here is what I have currently. I am not sure if there is any better
way to implement it?

{
    if(/^$/) {
        if(line != "") {
            if(!printed) {
                printed = 1
            } else {
                print ""
            }
            print line
            line = ""
        }
    } else {
        if(line == "") {
            line = $0
        } else {
            line = line " " $0
        }
    }
}
END {
    if(line != "") {
        if(!printed) {
            printed = 1
        } else {
            print ""
        }
        print line
    }
}
