"예쁜 인쇄"를 시도 중입니다.예약된 고정 IP공개 라우터 뒤에 있는 "장치"에 SSH를 통해 접속합니다. 입력 파일:

원하는 출력:(가능하다면 "-->와 유사하게 결과를 IP별로 오름차순으로 정렬합니다.| sort -t. -k1,1n -k2,2n -k3,3n -k4,4n -V"

device ip       device mac           device name

시도했지만 awk '/option ip/ {printf $3; } /option mac/ {printf $3; } /option name/ { print $3 $4; }'입력 파일의 "데이터 블록 형식"이 일치하지 않습니다.

답변1

문서 sort.awk:

function printentry(arg1, arg2, arg3){
  if (arg1!="") printf "%-15s   %-17s   %s\n", arg1, arg2, arg3
}
BEGIN{ 
  printentry("device ip", "device mac", "device name")
}
$0=="config host"{
  printentry(ip, mac, name)
  ip=mac=name=""
  next
}
$2=="ip"  { sub(/^[^\047]*/, ""); gsub(/\047/, ""); ip=$0;   next }
$2=="mac" { sub(/^[^\047]*/, ""); gsub(/\047/, ""); mac=$0;  next }
$2=="name"{ sub(/^[^\047]*/, ""); gsub(/\047/, ""); name=$0; next }
END{
  printentry(ip, mac, name)
}

산출:

$ awk -f sort.awk file
device ip         device mac          device name
192.168.1.14      eb:7f:29:10:19:14   DEVICE 14
192.168.1.11      3f:05:99:b9:73:11   DEVICE 11
192.168.1.54      37:10:81:f2:bb:54   DEVICE 54
192.168.1.55      62:f7:62:fc:75:55   DEVICE 55
192.168.1.8       45:70:a8:83:bd:08   DEVICE 08

또는 IP별로 정렬:

$ awk -f sort.awk file | sort -t. -n -k1,1 -k2,2 -k3,3 -k4,4
device ip         device mac          device name
192.168.1.8       45:70:a8:83:bd:08   DEVICE 08
192.168.1.11      3f:05:99:b9:73:11   DEVICE 11
192.168.1.14      eb:7f:29:10:19:14   DEVICE 14
192.168.1.54      37:10:81:f2:bb:54   DEVICE 54
192.168.1.55      62:f7:62:fc:75:55   DEVICE 55
