有个问题比较奇怪，请各位大侠帮忙看看。

$ ./TransferDataFromDatabaseToFile "select * from dual" "/tmp/a/b/c/" "a.out" "idsexchange" "idssys" "idssys"
SUCCESS
$ more TransferDataFromDatabaseToFile.sh
#!/bin/sh

para1=$1
para2=$2
para3=$3
para4=$4
para5=$5
para6=$6

echo para1=$para1
echo para2=$para2
echo para3=$para3
echo para4=$para4
echo para5=$para5
echo para6=$para6

`./TransferDataFromDatabaseToFile $para1 $para2 $para3 $para4 $para5 $para6`

echo SUCCESS
$ ./TransferDataFromDatabaseToFile.sh "select * from dual" "/tmp/a/b/c/" "a.out" "idsexchange" "idssys" "idssys"
para1=select TransferDataFromDatabaseToFile TransferDataFromDatabaseToFile.sh core from dual
para2=/tmp/a/b/c/
para3=a.out
para4=idsexchange
para5=idssys
para6=idssys
./TransferDataFromDatabaseToFile.sh[17]: 1257652 Segmentation fault(coredump)
SUCCESS

直接在TransferDataFromDatabaseToFile.sh里面调用
./TransferDataFromDatabaseToFile "select * from dual" "/tmp/a/b/c/" "a.out" "idsexchange" "idssys" "idssys"
也是正常运行的。
