Full Discussion: su (-) command

Kelam,

Setting a alias such as you suggest brings about a problem - if the alias is set and the user still does su -, the system will think the user wants to su - to userID - (which it then informs you does not exist).

medusa% alias su 'su -'
medusa% su
Password:
Sun Microsystems Inc. SunOS 5.8 Generic February 2000
[root@medusa]:/root
# exit
medusa% su -
su: Unknown id: -


You at least read the post more carefully than I as I thought the PzYon wanted it so they could not do su -. The logic in the script could still be done. The alias solution might work but a more intracate solution would be needed.

FINGER.CONF(5)						      BSD File Formats Manual						    FINGER.CONF(5)

NAME
finger.conf -- finger(1) alias configuration file DESCRIPTION
The optional finger.conf file is used to provide aliases that can be fingered by local and network users. This may be useful where a user's login name is not the same as their preferred mail address, or for providing virtual login names than can be fingered. Lines beginning with ``#'' are comments. Other lines must consist of an alias name and a target name separated by a colon. A target name should be either a user, a forward reference to another alias or the path of a world readable file. Where an alias points to a file, the contents of that file will be displayed when the alias is fingered. FILES
/etc/finger.conf finger(1) alias definition data base EXAMPLES
# /etc/finger.conf alias definition file # # Format alias:(user|alias) # # Individual aliases # markk:mkn john.smith:dev329 john:dev329 sue:/etc/finger/sue.txt # # Network status message # status:/usr/local/etc/status.txt # # Administrative redirects # root:admin postmaster:admin abuse:admin # # For the time being, 'sod' is sysadmin. # admin:sod SEE ALSO
finger(1) HISTORY
Support for the finger.conf file was submitted by Mark Knight <markk@knigma.org> and first appeared in FreeBSD 4.2. BSD
August 16, 2000 BSD
