RudiC:

Sorry for not providing detailed information. I will pay attention future.
Based on vgersh99's advice. I looked at directory settings. I found that my setting had problem. Since no data in working directory, I do go to /mydirectory/archive to execute script and put output file in /mydirectory. This may be the cause to make echo for ...loop can put output on screen and cannot log output into a file. Then I copy some files to /mydirectory and invoke script in the same directory. Now it works. This is my ignorance on directory setting. But thanks for RudiC and vgersh99's help.
