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
