使用printf语句来处理字符串的格式化和放置。当然你需要根据你的要求修改它。你必须根据你的要求玩变量v和j的值。使用命令替换在echo语句中使用了awk语句。

 echo "Random data is : $(awk -v f="%35s\n" -v j="%20s\n" 'NR>1{printf f,$0} NR==1 {printf j,$0}' abc.txt) "
Random data is :         Data is here
                          ASDF 1234
                         GHJKL 5678
                         !@#$% 0011
