If I run rg in bash directly, the output information includes the found file names (on a separate line), and then on a separate line for each match the line number and content for that match:
11:38 (main *+) durl $ rg format
durl/__main__.py
35: print(util.format_output(repo.url, line))
38: print(util.format_output(repo.url, line, linenumber=n))
durl/util.py
15:def format_output(prefix, filename: str, linenumber: str=None) -> str:
But if I run the same command from python subprocess run, the displayed information of the matched results includes the filename on each line and do not include a line number. Why is that so? (I am running on MacOS)
11:38 (main *+) durl $ ipython
