I apologize in advance if the message do not seem appropriate here but i believe it is the good place.

I got this strange error when i execute my bash script:

./cluster_bootstrap.sh 

./cluster_bootstrap.sh: line 15: $'r': command not found

./cluster_bootstrap.sh: line 91: warning: here-document at line 37 delimited by end-of-file (wanted `EOF')

./cluster_bootstrap.sh: line 92: syntax error: unexpected end of file

Meanwhile everything seems correct when i copy paste the script in my shell.
Any idea of this odd behaviour ?

PS: Here is my script:
