modify PS4 to output more information for BASH debugging #81

Closed guoqing-noaa closed 2 months ago

guoqing-noaa commented 2 months ago

Use the following line at the beginning of every runtime BASH script (J-job, ex-scripts, and ush scripts) excluding sourced scripts.

declare -rx PS4='+ $(basename ${BASH_SOURCE[0]:-${FUNCNAME[0]:-"Unknown"}})[${LINENO}]${id}: '

so we can output information similar to the following to facilitate BASH debugging:
