A login shell is what it says it is. A shell created as a consequence
of logging in. That could be a console login in run level 3, the GUI
login screen in run level 5, an ssh login from a remote system, etc.
Starting, for example, "gnome-terminal", does not constitute a login shell.
I also forgot to mention the "-i and -l" parameters on the
#!/bin/bash
line of a shell script that would also affect the type of shell.
One thing you can do to learn when .bashrc and .bash_profile are
sourced
is to add something like....
touch /tmp/bashrc.time to the end of your .bashrc file and a similar
line to your .bash_profile. Then you can
"ls -l --time-style=full-iso" (to display the seconds).
I also think you may want to learn about PID's and PPID's (Process ID,
and Parent Process ID).
