我有下面的shell脚本,可以根据需要生成输出。
RuleNum=$1
cat input.txt |awk -v var=$RuleNum '$1==var {out=$1; for(i=NF;i >=0;i--)if($i~/bps/){sub("bps","",$i);out=out" "$i} print out;out=""}'
./downup.sh 20
20 BW-IN:2560000 BW-OUT:2048000
我希望输出如下
./downup.sh 20
256000 2048000
./downup.sh 36
2560000 2048000
下面的是input.txt

答案 0 :(得分:0)
在现有sub("BW.*:", "", $i)
之后添加sub()
。
并且cat
没有必要。只需将文件名放在行尾:
awk ... input.txt
要从输出中删除规则编号,请删除out = $1;
。
这是添加的结果,以避免在每行的开头打印空格:
awk -v var=$RuleNum '$1==var {for(i = NF; i >= 0; i--) if ($i ~ /bps/) {sub("bps","",$i); sub("BW.*:", "", $i); out = out delim $i; delim = OFS} print out; out = delim = ""}'
