我的文件内容如下:
20 name:abc addr:203.45.247.247/255.255.255.255 WDW-THRESH:12 BW-OUT:10000000bps BW-IN:15000000bps STATSDEVICE:test247 STATS:Enabled (4447794/0) <IN OUT>

使用以下awk脚本:
awk -F"[: ]" '{out=$1; for(i=2;i<=NF;i++)if($i~/bps/){sub("bps","",$i);out=out" "$i} print out;out=""}' input.txt
我得到了这个输出:
20 10000000 15000000
25
37 192000
62 256000
但我希望这个输出:
20 15000000 10000000
25
37 192000
62 256000
答案 0 :(得分:4)
反转循环
awk -F"[: ]" '{out=$1; for(i=NF;i >1;i--)if($i~/bps/){sub("bps","",$i);out=out" "$i} print out;out=""}' file.txt
无需在循环中检查$ 0和$ 1。 $ 0是整行,$ 1已包含在输出中
答案 1 :(得分:0)
也许“BW-IN”和“BW-OUT”并不总是以相同的顺序出现。
awk -F"[: ]" '
{
out = $1;
for (i = 2; i <= NF; i++) {
if ($i ~ /bps/) {
sub("bps", "", $i);
if (! flag) {
out = out " " $i save
} else {
flag = 0
save = " " $i
}
}
if ($i == "BW-OUT") {
flag = 1
}
}
print out;
out = save = ""
}
