Logon
Sequence (continued)
You are
placed in the default shell as defined by the passwd
login account file when you first log in to the system.
By using
the command sh
(Bourne shell), csh
(C shell), or bash
(Bash shell), a shell within the current shell, a subshell,
will be created. You can repeat this process to create more subshells.
Type exit
or press Control
+ d to move back to the previous shell.
Note:
Control + d does not work on all distributions.
The following
table shows how the initialization files are read. We will assume
that the .bashrc,.profile,.cshrc,
and the . login files are located in the user's $
HOME directory.
