sed, awk 패턴 1 라인을 복사하여 다음 패턴 2 라인에 붙여넣기

그리고 sed:

sed '/^-country/{p;d};/^-city/{h;p;d};/^$/!{G;s/\n/ /}' test_file

여러 줄 주석으로:

sed '
    /^-country/{p;d;}; # If found a country print and go to the next line
    /^-city/{h;p;d;};  # If found a city save the line, print and go to the next line
    /^$/!{G;s/\n/ /;}; # For any, non empty lines, get the one saved before and attach it to the current line.
' file

---

그리고 awk:

awk '/^-city/{h = $0} NF && !/^-(country|city)/ {$0 = $0 " " h} 1' test

기본적으로 위와 동일합니다 sed.

-city"save"로 시작하는 줄이 발견된 경우.

그런 다음 비어 있지 않은 각 줄(줄 -country이나 -city줄 자체가 아님)에 대해 이전에 저장된 줄에 연결된 현재 줄을 인쇄합니다.
