Hello All, I am running with Python 2.7 I have to run script that could have get arguments in two ways: 1. argument + file name. 2. argument + input from pipe.
example for 1: ./my_script.py -t 1,2,3 file_name.txt example for 2: grep snd file_name.txt | ./my_script.py -t 1,2,3 I am using "parse_known_args" to parse the rest of args when pipe exists. and capture with: "fileinput". My problem is that this does not run always, for second option. Any idea how could I get standard input with additional flag? for example, running with pipe option will be like this: grep snd file_name.txt | ./my_script.py -t 1,2,3 - where the additional "-" at the end will indicate script to get standard input.
