.sh文件的一些坑

Windows下编辑的.sh文件，放到Ubuntu上运行./eval.sh，报错：

1. -bash: ./eval.sh: Permission denied

2. -bash: ./eval.sh: /bin/bash^M: bad interpreter: No such file or directory

解决方法：

1）-bash: ./eval.sh: Permission denied

chmod +x ./eval.sh

2）-bash: ./eval.sh: /bin/bash^M: bad interpreter: No such file or directory

1. vi ./eval.sh
2. :set ff=unix
3. :wq
4. 重新运行./eval.sh就可以了
