Nagios XI - Uploaded plugin returns "/bin/bash^M: bad interpreter: No such file or directory"

Problem Description

After uploading a plugin (check_apc_pdu_load.sh for example), the following error is produced:

The following error message is produced:

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

This is caused by the file being in a "Windows" format instead of a "Unix" format. It has to do with the line endings / carriage returns.

 

Resolving The Problem

To resolve the problem you will convert the file to a Unix format. Execute the following steps from an SSH session as a user with root privileges.

The first step is to install the required package:

RHEL | CentOS | Oracle Linux

yum install -y dos2unix

 

Debian | Ubuntu

apt-get install -y dos2unix

 

The next step is to convert the file to a Unix format:

dos2unix /usr/local/nagios/libexec/check_apc_pdu_load.sh


This will output:

dos2unix: converting file /usr/local/nagios/libexec/check_apc_pdu_load.sh to UNIX format ...

 

After completing these steps the plugin should execute as intended.
