while read t1 t2 t3 t4
do
echo $t2 $t4
sed 's/.*/sed eat the line ( & )/'
done <tt.log

看看这个例子，就知道其它的数据到哪儿去了吧？

这个解释帅呆了

[root@142 work]# while read kkk; do echo $kkk; sed 's/.*/sed eat the line ( & )/'; done <ytail.sh
#set nohup.out
sed eat the line (  )
sed eat the line ( back_off=${2:-39} )
sed eat the line ( for((;) )
sed eat the line ( do )
sed eat the line (      size=$(ls -l $1 | awk '{print $5}') )
sed eat the line (      hexdump -s $((size - back_off)) -C $1 | awk -F "|" '{printf $2}' )
sed eat the line (      echo )
sed eat the line (      sleep 5 )
sed eat the line ( done )
sed eat the line (  )
