linux用exec命令查找永无止境

Question

This is the command i am invoking:

find / -name zad1.sh -size -50M -mtime -1 -exec grep "do" {} \;

Then it echo's two lines which are correct:

do
done

But then, it continues doing something and never stops. I have to kill the process manually doing Ctrl+C. Can anyone explain to me what happenned here? PS Im new to Unix-like systems.(im working on Cygwin)

You have to add -quit option; from the manpage:

-quit  Exit immediately.  No child processes will be left running,  but
          no  more  paths specified on the command line will be processed.
          For example, find /tmp/foo /tmp/bar -print -quit will print only
          /tmp/foo.   Any  command  lines  which  have  been built up with
          -execdir ... {} + will be invoked before find exits.   The  exit
          status may or may not be zero, depending on whether an error has
          already occurred.

Ps. change the "do" with 'do' ; double quotes interpolates the string within and do is a keyword for bash.
