Re: how could I execute a set of script in a directoy tree?

[龙海涛]

sorry to reply late.
i have used your method , it works.

two more questions:
1.about syntax (r "$d") 
i didn't find any introduction in 'info bash'. could you tell me how
could find the explanation of '( )'?

2.about synax  "find /testcase -name autotest.sh -perm /111 -execdir
bash -c ./autotest.sh \;"
what does the last '\' mean?

3x again
