and I thought you could do anything in unix (well at least to the variable of time)
cheers for the reply peoples, very much appreciated for the thoughtful responses.

however I just have a supplementry question for LivinFree: In regards to the function, can you please explain what is happening or point me to a place I can find it? I've never come across functions with the same syntax before in a bourne shell and would like to find out more.

And can it handle any number of directories?

Quote:
What about using a function?

Put something like this in your .profile or .bash_profile:

goto () {
${PWD%/*/*/*}/${1}/${PWD#/*/*/*/}
}

Then you could be in /usr/bin/xtra/test/test3/, type "goto null", and you'd then be in /usr/bin/null/test/test3/. mentry question for livingfree


Ok, now that i have tested this command I have a better idea what is happening, however it really isn't what I want.

Only because it doesn't work from any directory level and when it is in the right directory structure I only get something like this

(shakey on prodsrv)/usr/bin/code/training/shakey>goto lib
bash: /usr/bin/lib/training/shakey: is a directory

Although I like the idea of it being in the .bash_profile rather than a script.

Any alternate ideas or can we work from here somewhere?

Thanks

setusershell

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME

       getusershell, setusershell, endusershell - get legal user shells

SYNOPSIS

       #include <unistd.h>

       char *getusershell(void);

       void setusershell(void);

       void endusershell(void);

DESCRIPTION

       The  getusershell()  function  returns  a  pointer  to  a  legal  user  shell  as defined by the system manager in the file /etc/shells. If
       /etc/shells does not exist, the following locations of the standard system shells are used in its place:

       /bin/bash		  /bin/csh
       /bin/jsh 		  /bin/ksh
       /bin/pfcsh		  /bin/pfksh
       /bin/pfsh		  /bin/sh
       /bin/tcsh		  /bin/zsh
       /sbin/jsh		  /sbin/pfsh
       /sbin/sh 		  /usr/bin/bash
       /usr/bin/csh		  /usr/bin/jsh
       /usr/bin/ksh		  /usr/bin/pfcsh
       /usr/bin/pfksh		  /usr/bin/pfsh
       /usr/bin/sh		  /usr/bin/tcsh
       /usr/bin/zsh		  /usr/xpg4/bin/sh

       The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells.

       The setusershell() function rewinds the file or the list.

       The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells.

RETURN VALUES

       The getusershell() function returns a null pointer on EOF.

BUGS

       All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved.
