问题 I want to write a CLI hello that takes a FILENAME as an argument except when the option -s STRING is given, in which case the STRING is processed directly. The program should print hello {NAME} where name is either given via the STRING or taken to be the contents of the file FILENAME. example : $ cat myname.txt john $ hello myname.txt hello john $ hello -s paul hello paul A possible workaround is to use two options: @click.command() @click.option("-f", "--filename", type=str) @click.option("

The two process are likely to be long running (assume minutes) and the output must be available as the processes process the data (think tail -f). To re-inforce the last point the process may output large
