服务器SSH反向隧道列表及状态显示

觉得利用临时文件来保存中间结果的方法太耗费资源，又改了一下脚本，利用变量来保存中间结果。

1. show_port(){
   
2. result1=$(grep 127 ~/.bash_profile |awk -F'[= ]' '/-p [0-9]+.*/{printf("%-20s\t%d\n",$2,$(NF-2))}')
   
3. result2=$(find /home/enb  -type f -name 'z.port*'|xargs egrep -H '[0-9]+'|awk -F. 'split($NF,a,":"){printf("%-20s\t%d\n",a[1],a[2])}')
   
4. alive=$(netstat -ta|awk -F"[ :]+" '/localhost:/{print$5}')
   
5. final=$(echo -e "$result1\n$result2"|awk -va="$alive" -vOFS='\t' '{print $0,(a~$2)?"on":"off"}')
   
6. printf %-20s"\t"%s"\t"%s"\n" Host Port Status
   
7. echo "--------------------------------------"
   
8. echo "$final"|grep on|sort -nk2
   
9. echo "--------------------------------------"
   
10. echo "$final"|grep off|sort -nk2
    
11. }
