            假设qq.tel文件内容:

              12334:13510014336

              12345:12334555666

              12334:12343453453

              12099:13598989899

              12334:12345454545

              12099:12343454544

            分类如下:

              [12334]

                  13510014336

                  12343453453

                  ...........

              [12099]

                  13598989899

                  12343454544

                  ............

          实现如下:

                                sort  qq.tel| awk  -F‘:‘   ‘{if(tmp!=$1)   {tmp=$1;print "["tmp"]";}  print $2;}‘  #tmp可以换成其他字符
