Hi guys,
I have a question. In the passwd file, user johndoe has a GID of 100 which is the group named users in the group file. But if you check the group file, johndoe is not listed under GID 100, but under GID 33, which is the group named videos. Under what group does johndoe really belong,... (1 Reply)

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.
