답변1

잘 알려진 sed 레시피의 변형을 사용할 수 있습니다.

sed -e :a -e '$!N;/\n.*:/!s/\n/ /;ta' -e 'P;D' test.txt

즉, 이전 줄이 있으면 그 줄 뒤에 줄을 추가합니다(개행 문자를 공백으로 바꿈).아니요콜론이 포함되어 있습니다. 그래서 주어진

$ cat -n test.txt

awk를 사용하십시오.

$ awk '/:/{if (NR>1) print r; r=$0; next} {r=r OFS $0} END{print r}' file

답변3

사용 awk:

$ awk '{printf "%s", (($1 ~ /:$/) ? ((NR==1) ? "" : ORS) : " ")$0 } END{print ""}' file
# Or
$ awk -v ORS=' ' '{NR!=1 && gsub(/[[:alnum:]]+:/, "\n&")}1; END{printf "\n"}' file | sed 's/ $//'

@EdMorton이 제안한 대로:

입력에 printf 형식 문자(예: )가 포함된 경우 후자가 실패하고 ORS의 값을 사용하는 전자보다 낫고 ORS에 원하는 하드 코딩된 값을 사용하는 후자가 있으므로 항상 printf "%s", $n대신 수행하십시오 .printf $n%sprint ""printf "\n"
