BASH:/usr/bin/autocrorder:/usr/bin/python^m:bad interpreter:no such file or Directory_linux shell

A Python script written under Windows system that is given permissions under Linux chmod +x xxx.py after execution./xxx.py run prompt: bash:/usr/bin/autocrorder:/usr/bin/python^m: Bad interpreter:no such file or directory

Analysis:

This is caused by different system encoding formats: the. Sh. py file that is edited in the Windows system may have invisible characters, so it will report the above exception information in the Linux system. This is typically caused by a difference between the end of the Windows line and the end of the Linux line.

Solve:

1 conversion under Windows:

Use tools such as UltraEdit or editplus to convert scripts to code and then execute them in Linux. The conversion method is as follows (UltraEdit): File-->conversions-->dos->unix.

2) direct replacement under Linux:

Sed-i ' s/^m//g ' filename (note that ^m is written under Linux by ^m is a carriage return line feed, the input method is to hold down CTRL + V, Release v., press M)

3) can also be converted in Linux:

First, make sure the file has executable permissions

Copy Code code as follows:

#sh >chmod a+x filename

Then modify the file format

Copy Code code as follows:

#sh >vi filename

Use the following command to view file formats

: Set FF or: Set FileFormat

You can see the following information

Fileformat=dos or Fileformat=unix

Use the following command to modify the file format

: Set Ff=unix or: Set Fileformat=unix

: Wq (Disk exit)

Final File Execution
#sh >./filename
