Difference between Login Shell and Non-Login Shell?
4 answers
Why we can not see a single hyphen from $0 on a login shell invoked with `--login` option?
2 answers
When I open a terminal on my own computer and run echo $0, I get /bin/bash - which is the name of the executable being run.
However, when I run echo $0 in an ssh session, I get -bash. Why? What does the dash mean? It's not like there is a command named -bash.
