E.g something that prints a sort of execution log like "calling line 1", "calling line 2" etc. 回答1: sh -x script [arg1 ...] bash -x script [arg1 ...] These give you a trace of what is being executed. (See also 'Clarification' near the bottom of the answer.) Sometimes, you need to control the debugging within the script. In that case, as Cheeto reminded me, you can use: set -x This turns debugging on. You can then turn it off again with: set +x (You can find out the current tracing state by analyzing $
