1）問題現象：

在ubuntu下執行以下腳本( while_count),報錯：

-bash: ./while_count: /bin/bash: bad interpreter: Text file busy

2）問題原因：

This happens because the script file is open for writing, possibly by a rogue process which has not terminated.

3）解決辦法：

Solution: Check what process is still accessing the file, and terminate it.

Run lsof (list open files command) on the script name:

lsof | grep while-count
cat 17653 me 1w REG 8,1 148 181517 /home/me/test/while-count

kill -9 17653

Now try running the script again. It works now.
