WWN从10进制转换成16进制，并添加冒号分隔符

#!/bin/bash
function addsep()
{
echo $1|awk 'BEGIN{FS="";ORS=""}{for(x=1;x<=NF;x++){if(x%2==0)print $x":";if(x%2==1)print $x}print"\n"}'|sed 's/:$//g'
}

echo 1152922127287633521|while read wwn
do 
wwn1=`printf "%x\n" $wwn`       #10进制转换成16进制
wwn2=`addsep $wwn1`              #将字符串转换成：分隔格式
echo $wwn2
done
