Re: profile

Both are user profiles. Depends on the shell for the user, corresponding profile will be used.

Re: profile

Hi,

You need to learn the basics then. These are different login shells which will be executed at the time of user logs in. Each shells has its own capablities and features.
It will be specified in /etc/passwd file.

Basic definition of shell:

Users of the UNIX system don't have a direct interaction with the kernel. Instead, the
user always works with a program called the UNIX shell. A shell can be considered a
command interpreter. The shell takes user commands, interprets them, and takes the
necessary action to execute them. It also provides the output of these commands to the
user.

C shell:
It uses a C language-like syntax for shell programming.

Korn shell:
It has more complex and advanced features than the Bourne or C
shell and takes more time to master
Best wishes,

Ganesh.

Re: profile

There are different shells
/bin/sh Bourne shell
/bin/bash The Bash shell
/bin/ksh Korn shell
/bin/csh C shell

and many more and they have initialization files .profile for korn and sh and .login .cshrc for csh

the system wide initialization file is the /etc/profile where you have the umask set so that it reflects for the created users.

>>/bin/sh Bourne shell

Not correct, at least in HP-UX!

/sbin/sh and /usr/bin/sh (/bin/ is a link to /usr/bin) is the **POSIX** shell, **NOT** the Bourne shell.

# man sh-posix
