IMEX daemon template: fix echoing nodes config

[jgehrcke]

I don't quite understand this, but with the recent patch #298 in the output we see:

$ kubectl logs -n nvidia-dra-driver-gpu   repro2-compute-domain-x6dpf-m6z2l
-e /etc/nvidia-imex/nodes_config.cfg:


10.115.131.12

The fact that "-e" appears in the output is surprising. This should be a command line argument to echo. On my machine:

$ echo -e "test \n\n"
test 

Is that a different echo?

Pull Request Overview

This PR aims to fix the output format for the nodes configuration in the IMEX daemon template by removing the unintended echo behavior caused by the "-e" flag.

• Removed the "-e" flag from the echo command to prevent it from being printed in the logs
• Separated the header echo and the file content cat commands for improved clarity

Comments suppressed due to low confidence (1)

• [nitpick] Removing the -e flag prevents escape sequence interpretation. If the original formatting (i.e., additional newlines) was needed for clarity in the log output, consider explicitly adding the necessary newlines.

echo "/etc/nvidia-imex/nodes_config.cfg:"

[jgehrcke]

Yes. Different echo.

echo -e is a nonstandard bash extension. Not only is it not required by the standard, it's not even allowed by the standard, which explicitly states that "Implementations shall not support any options".
