su bin -c ’echo hello’
Become user DCEPrincipal in the DCE environment:
su -d DCEPrincipal
WARNINGS
After a valid password is supplied, su
uses information from /etc/passwd and /etc/logingroup
to
determine the user’s group ID and group access list. If
/etc/group is linked to /etc/logingroup
,
and group membership for the user trying to log in is managed by the Network Information Service (NIS),
and no NIS server is able to respond,
su waits until a server does respond.
DEPENDENCIES
Pluggable Authentication Modules (PAM)
PAM is an Open Group standard for user authentication, password modification, and account validation. In
particular,
pam_authenticate()
is invoked to perform all functions related to
su. This includes pass-
word retrieval, account validation, and error message displays.
