The cd command is built into the shell, so there is no /bin/cd. Interesting story: originally Ken and Dennis didn't realize that cd needed to be built into the shell. It took them a while to realize that since each process has a current directory the cd command that they wrote didn't have any effect. They then merged the code into the shell.
Note: restricting cd does not prevent users from accessing files in other directories. Restricting cd does not enhance security enough to be worth while. -----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of Lloyd Fuller Sent: Friday, May 20, 2005 8:21 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: Linux default permissions On Fri, 20 May 2005 10:12:15 -0500, Tom Duerbusch wrote: > >So, is there any way to restrict a Linux user from being able to CD >away from their home directory?

For those users that you want to restrict, can't you change their profiles to alias cd so it does nothing? Or replace cd in their /bin with a new program that just exits. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
