리눅스의 경우인데, solaris에서도 통할지는???

: 아래 질문드렸던 su에 관해서... 다시 심각한 문제에 봉착했습니다. T.T
: 리눅스 서버에서는 su가 -s 옵션이나 --shell이 있어서 될줄 알았는데..
: 정작 문제의 Soloaris서버에서 실행해보니 -s옵션이나 --shell이 아예 없습니다.. T.T
: 아래는 문제의 su의 man페이지입니다..

: Maintenance Commands su(1M)

: NAME
: su - become super user or another user
:
: SYNOPSIS
: su [ - ] [ username [ arg ... ] ]
:
: DESCRIPTION
: su allows one to become another user without logging off.
: The default user name is root (super user).
:
: To use su, the appropriate password must be supplied (unless
: the invoker is already root). If the password is correct,
: su creates a new shell process that has the real and effec-
: tive user ID, group IDs, and supplementary group list set to
: those of the specified username. The new shell will be the
: shell specified in the shell field of username's password
: file entry (see passwd(4)). If no shell is specified,
: /usr/bin/sh is used (see sh(1)). To return to normal user
: ID privileges, type an EOF character (CTRL-D) to exit the
: new shell.
:
: Any additional arguments given on the command line are
: passed to the new shell. When using programs such as sh, an
: arg of the form -c string executes string using the shell
: and an arg of -r gives the user a restricted shell.
:
: The following statements are true only if either /usr/bin/sh
: or NULL is named in the specified user's password file
: entry. If the first argument to su is a ' - ' (dash), the
: environment is passed along unchanged, as if the user actu-
: ally logged in as the specified user. Otherwise, the
: environment is passed along, with the exception of $PATH,
: which is controlled by PATH and SUPATH in etc/default/su.
:
: All attempts to become another user using su are logged in
: the log file /var/adm/sulog (see sulog(4)).
:
: 제가 배운 영어가 틀리지 않다면.. 여기서 su는 무조건 passwd파일을 참조해서
: 쉘을 실행시키는 것 같습니다.. T.T
: 그러니 아무리 su -s /bin/csh이나 su - --shell=/bin/csh을 줘도 소용이
: 없습니다..
: 아.. 어찌해야하나요..
