Summary
When running a script in Bamboo it fails and shows "'\r': command not found" and other syntax errors.
Environment
Bash Script created/edited on Windows OS.
Diagnosis
Looking at the logs of a failed build, the following errors can be seen:
'\r': command not found
syntax error near `]]
syntax error in conditional expression
Illegal characters found in URLCause
The issue is caused when the script file has a line ending formatting from Windows which is not recognized by bash causing syntax errors. This can happen if the script file being used was, at some point, edited in a Windows machine or had its encoding changed.
Solution
To resolve this issue you can use Dos2Unix or a similar tool to convert the script file encoding from Windows to Unix encoding. For example:
dos2unix script.sh
