Thanks, I am sure that is true, but as I am just starting out, and wanted to run through this tutorial:
UNIX / Linux Bourne / Bash Shell Scripting Tutorial [ steve-parker.org ]

which is written with the bourne shell in mind. It is easier for me if I start from the correct shell.

That way at least I know that when something goes wrong, it is something I have done rather than a difference between the tutorial (sh) and the shell I am using (csh)

The very first line in the tutorial gets you to change the prompt to $.

The command given failed and I assumed I must have been doing something wrong. Turns out that it was the shell differences. I needed to use set prompt="$ " and not what the tutorial gave.

Since I first posted, I managed to edit the passwd file and save it to the local HDD, and using the post init command section of the FreeNAS WebGUI, managed to get it to copy across on boot up.

Still did not change the user shell though, although the edited and copied version is in /etc.

I did forget to mention that I am accessing the box remotely on the local network using PuTTy.

I tried using:
exec bash
It just closed the Putty window down immediately on hitting the RETURN key...but if it had worked, would that not have put me in a bash shell rather than sh?

Change default shell of a specific user with awk

I would like to replicate the functionality of chsh (or passwd -e) by awk. This is what I got so far, but I think there should be an easier way to search and replace field $7 only for lines beginning with user_name: awk -v user_name="$user_name" -v new_shell="$new_shell" -F: '$1 == user_name {...

chsh

chsh(1) 						      General Commands Manual							   chsh(1)

NAME

       chsh - change login shell

SYNOPSIS

       chsh [-D binddn] [-P path] [-s shell] [-l] [-q] [-u] [-v] [user]

DESCRIPTION

       chsh  is  used  to  change  the	user login shell.  A normal user may only change the login shell for their own account, the super user may
       change the login shell for any account.

       If a shell is not given on the command line, chsh operates in an interactive fashion, prompting the user  with  the  current  login  shell.
       Enter  the  new	value  to change the field, or leave the line blank to use the current value. Enter none to remove the current value.  The
       current value is displayed between a pair of [ ] marks.

       The only restrictions placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker  is  the  super-
       user, and then any value may be added.  An account with a restricted login shell may not change their login shell.

       This version of chsh is able to change the shell of local, NIS, NIS+ and LDAP accounts , if the permissions allow it.

OPTIONS

       -D, --binddn binddn
	      Use  the	Distinguished  Name binddn to bind to the LDAP directory.  The user will be prompted for a password for simple authentica-
	      tion.

       -P, --path path
	      The passwd file is located below the specified directory path. chsh will use this files, not /etc/passwd.  This is useful for  exam-
	      ple  on  NIS master servers, where you do not want to give all users in the NIS database automatic access to your NIS server and the
	      NIS map is build from special files.

       -s, --shell
	      Specify your login shell.

       -l, --list-shells
	      Print the list of shells listed in /etc/shells and exit.

       -q, --quite
	      Don't be verbose.

       -u, --usage
	      Print a usage message and exit.

	   --help
	      Print a more verbose help text and exit.

       -v, --version
	      Print version information and exit.

FILES

       /etc/passwd - user account information
       /etc/shells - list of valid login shells

SEE ALSO

       chfn(1), passwd(5), shells(5)
