同時tail多個文件

普通的tail命令只能查看一個文件的輸出，保存如下內容為multail.sh  

#!/bin/sh
function clean()
{
  #echo $@;
  #for file in "$@"; do ps -ef|grep $file|grep -v grep|awk '{print $2}'|xargs kill -9; done
  jobs -p|xargs kill -9  
}
files=$@

# When this exits, exit all back ground process also.
#trap "ps -ef|grep tail|grep -v grep|awk '{print "'$2'"}'|xargs kill -9" EXIT

trap "clean $files " EXIT

# iterate through the each given file names,
for file in "$@"
do
        # show tails of each in background.
        tail -f $file &
done

# wait .. until CTRL+C
wait
