Depending on the permissions of the directories, could you do something like: 1) login as another ordinary user 2) copy the real shell under the directory and name you had incorrectly set 3) login under that account, using the 'classical' shell in its new, 'phony' location 4) become 'su' and fix things up Just a thought. - John Mills To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message

I tried it with a test account and vipw not told me about the wrong path of the shell... but chsh does.

Or perhaps the immutible flag set on /etc/passwd by default and have vipw and adduser (un)set this automagically when used. - Mike > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA1 > > >> (10.21.2002 @ 1514 PST): Bsd Neophyte said, in 0.8K: << > > > > --- "DaleCo, S.P.---'the solutions people'" <[EMAIL PROTECTED]> wrote: > > > Do you have a passwd for "toor"? > > > > no... i don't... > >> end of "Re: made a mistake with bash path... now i can't login" from Bsd N > eophyte << > > if you're going to edit your passwd file and change shells or whatnot, > use the vipw command. if you specify an invalid shell, vipw will tell > you. > > perhaps it'd be useful to have "don't edit this directly - use vipw(8)" > at the top of /etc/passwd... > > - -Adam > > > - -- > Adam Weinberger > [EMAIL PROTECTED] > [EMAIL PROTECTED] > > -BEGIN PGP SIGNATURE- > Version: GnuPG v1.2.0 (FreeBSD) > > iD8DBQE9tILMo8KM2ULHQ/0RAhKPAJ9H7At4KqTygsjZjKi01lXRRucLjACbBAGX > H53fjFExlu+UHXkKJQW2/dc= > =cvM+ > -END PGP SIGNATURE- > > To Unsubscribe: send mail to [EMAIL PROTECTED] > with "unsubscribe freebsd-questions" in the body of the message To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message

All you have to do is boot to single user and un-fubar your system. It asks what shell and you mount your system and provide root with a good shell. You are seeing one of the reasons that many of us leave root as its default cshell.

Or have I misunderstood this question completely? no you have it right... this is an option, although i'd like to keep it a last option... disconnecing the machine and moving it would be a huge inconveniance. i was wondering if there was a way to tell the su command to use the /bin/sh shell... instead of what i mistakingly input (/usr/bin/bash). __ Do you Yahoo!?

Do you have local access to the machine? if so cant you just log in as root? Or have I misunderstood this question completely? It has been ages since I have used su (I use sudo) but as I recall you have to have the root password so login in locally as root shouldnt be a problem?

If you have any other non-root account which you can use to login, perhaps you can try to login using one of those accounts and then use su to login to the "bash" account with the -m option.
