如何将文件中的 IP 地址列表从 xxxx-xxxx 扩展为 xxxx-x 格式？

Question

IP范围10.0.0.1-10.0.0.3可扩展至

10.0.0.1

10.0.0.2

10.0.0.3

通过使用这个脚本

eval printf '%s\\n' $(echo '10.0.0.1-10.0.0.3' | awk -F'[.-]' -v OFS='.' '{for(i=1;i<=4;i++) $i = "{" $i ".." $(i+4) "}"; NF=4} 1')

但如果我有一组这样的数据；

10.0.0.1-10.0.0.3

172.16.0.3

192.168.0.2-192.168.0.2

我如何产生这样的输出？

10.0.0.1

10.0.0.2

10.0.0.3

172.16.0.3

192.168.0.2

您能否尝试以下操作，仅在 GNU 中使用所示示例进行编写和测试awk。awk 'BEGIN{&nbsp; FS="-"&nbsp; OFS="."}$1==$2 || NF==1{&nbsp; print $1&nbsp; next}{&nbsp; num1=split($1,arr1,".")&nbsp; num2=split($2,arr2,".")&nbsp; for(i=arr1[num1];i<=arr2[num2];i++){&nbsp; &nbsp; &nbsp;print arr1[1],arr1[2],arr1[3],i&nbsp; }}' Input_file说明：对上述内容添加详细说明。awk '&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;##Starting awk program from here.BEGIN{&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ##Starting BEGIN section of this program from here.&nbsp; FS="-"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ##Setting field separator as - here.&nbsp;&nbsp; OFS="."&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;##Setting output field separator as . here.}$1==$2 || NF==1{&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ##Checking condition if 1st field is equal to 2nd field OR number of fields is 1 then do following.&nbsp; print $1&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ##Printing 1st field of current line here.&nbsp; next&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ##next will skip all further statements from here.}{&nbsp; num1=split($1,arr1,".")&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;##Splitting $1 into arr1 with delimiter .
