Unless you give a pathname for the command to be executed that contains a slash character, the command must be in a directory on your command search path. If you are using a shell that uses basic Bourne shell syntax, the command search path is specified by the PATH shell variable. If you issue the command:
echo "$PATH" you will see a list of directories separated by colons. Many administrators set up the default PATH for users on their system to include the current directory; others don't. It looks like yours doesn't. There are several ways to execute nu in this situation. They include:
Specify a pathname for your script that contains a /, such as:
Code:
./nu
Add the current directory to your PATH:
Code:
PATH="$PATH:."
then run:
Code:
nu
Move your shell script to a directory that is on your search path:
Code:
mv nu $HOME/bin
(at least most sysadmins will have this directory in your search path),and then run it:

su
SU(1) BSD General Commands Manual SU(1)NAME
su -- substitute user identity
SYNOPSIS
su [-flm] [login] [-c shell arguments]
DESCRIPTION
su requests the password for login and switches to that user and group ID after obtaining proper authentication. A shell is then executed,
and any additional shell arguments after the login name are passed to the shell. If su is executed by root, no password is requested and a
shell with the appropriate user ID is executed.
The options are as follows:
-c Invoke the following command in a subshell as the specified user.
-f If the invoked shell is csh(1), this option prevents it from reading the ``.cshrc'' file.
-l Simulate a full login. The environment is discarded except for HOME, SHELL, PATH, TERM, and USER. HOME and SHELL are modified as
above. USER is set to the target login. PATH is set to ``/bin:/usr/bin''. TERM is imported from your current environment. The
invoked shell is the target login's, and su will change directory to the target login's home directory. This option is identical to
just passing "-", as in "su -".
-m Leave the environment unmodified. The invoked shell is your login shell, and no directory changes are made. As a security precau-
tion, if the target user's shell is a non-standard shell (as defined by getusershell(3)) and the caller's real uid is non-zero, su
will fail.
The -l and -m options are mutually exclusive; the last one specified overrides any previous ones.
Only users in group ``wheel'' (normally gid 0) or group ``admin'' (normally gid 20) can su to ``root''.
By default (unless the prompt is reset by a startup file) the super-user prompt is set to ``#'' to remind one of its awesome power.
SEE ALSO csh(1), login(1), sh(1), skey(1), kinit(1), kerberos(1), passwd(5), group(5), environ(7)ENVIRONMENT
Environment variables used by su :
HOME Default home directory of real user ID unless modified as specified above.
PATH Default search path of real user ID unless modified as specified above.
TERM Provides terminal type which may be retained for the substituted user ID.
USER The user ID is always the effective ID (the target user ID) after an su unless the user ID is 0 (root).
HISTORY
A su command appeared in Version 7 AT&T UNIX.
