hi,
why is the ``-c'' (execute command) option of the ``su'' needed when i want
to execute a command as a different user? and why is this option not in the
manpage (its only found in the EXAMPLES section of su(1)):
su [-] [-Kflm] [-c class] [login [args]]
i find it a bit confusing that there is also a ``-c'' for the class.
it then says in su(1):
If the optional args are provided on the command line, they are passed to
the login shell of the target login.
so this porobably means that the ``-c command'' is then passed to the
login shell which might be i.e. /bin/sh. thus it ends up in:
/bin/sh -c command. but why do i needs this? it could also be
/bin/sh command, or?
regards,
cjm
