Category	Suggestion	Score
Best practice	Use printf instead of echo for more consistent handling of special characters Consider using printf instead of echo for more consistent behavior across different systems when dealing with special characters or escape sequences. Base/check-grid.sh [8] -BASIC_AUTH="$(echo -en "${SE_ROUTER_USERNAME}:${SE_ROUTER_PASSWORD}" | base64 -w0)" +BASIC_AUTH="$(printf '%s:%s' "${SE_ROUTER_USERNAME}" "${SE_ROUTER_PASSWORD}" | base64 -w0)" Apply this suggestion Suggestion importance[1-10]: 7 Why:	7
Maintainability	Improve code organization by grouping variable declarations together Move the BASIC_AUTH variable declaration to the beginning of the script, near other variable declarations, to improve code organization and readability.

Enhancement	Improve variable scope and reduce potential code duplication Consider moving the BASIC_AUTH variable declaration outside the if block to avoid potential repetition if the variable is used in multiple places. charts/selenium-grid/configs/node/nodeProbe.sh [39-42] +BASIC_AUTH="$(echo -en "${SE_ROUTER_USERNAME}:${SE_ROUTER_PASSWORD}" | base64 -w0)" + return_list=($(bash ${NODE_CONFIG_DIRECTORY}/nodeGridUrl.sh)) grid_url=${return_list[0]} grid_check=${return_list[1]} -BASIC_AUTH="$(echo -en "${SE_ROUTER_USERNAME}:${SE_ROUTER_PASSWORD}" | base64 -w0)" Apply this suggestion Suggestion importance[1-10]: 7 Why:	7
