change login dir

If this is for the root user, here is something I discovered the other day.
root:/root> cd
root:/root> echo $HOME
/root
root:/root> HOME=/
root:/root> cd
root:/> echo $HOME
/
root:/> HOME=/root
root:/> cd
root:/root>
root:/root> HOME=/usr/local/bin
root:/root> cd
root:/usr/local/bin> HOME=/root
root:/usr/local/bin> cd
root:/root>
There is a variable called $HOME. You can modify it to be what ever you want. When you type "cd" <enter> that is where you will go. As in the example above.
You can make this permanent by putting in the bottom of your .profile. export HOME=/some/dir.
This works for any user, even root and application user IDs.
root:/root> cd
root:/root> echo $HOME
/root
root:/root> HOME=/
root:/root> cd
root:/> echo $HOME
/
root:/> HOME=/root
root:/> cd
root:/root>
root:/root> HOME=/usr/local/bin
root:/root> cd
root:/usr/local/bin> HOME=/root
root:/usr/local/bin> cd
root:/root>

shtool-mkshadow
SHTOOL-MKSHADOW.TMP(1) GNU Portable Shell Tool SHTOOL-MKSHADOW.TMP(1) NAME
shtool-mkshadow - GNU shtool create shadow tree using symlinks SYNOPSIS
shtool mkshadow [-v|--verbose] [-t|--trace] [-a|--all] src-dir dst-dir DESCRIPTION
This command creates a shadow tree of src-dir under dst-dir by recreating the directory hierarchy of src-dir under dst-dir and by creating the files of src-dir by linking them into the corresponding directories under dst-dir via symbolic links. When src-dir can be reached via relative paths from dst-dir, relative symbolic links are used, too. This high-level functionality is originally designed for developers to create copies of source trees. OPTIONS
The following command line options are available. -v, --verbose Display some processing information. -t, --trace Enable the output of the essential shell commands which are executed. -a, --all Really shadow all files and directories in src-dir. Default is to skip CVS related files and directories, backup files, object files, etc. EXAMPLE
# shell script shtool mkshadow -v -a . /tmp/shadow HISTORY
The GNU shtool mkshadow command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1998 for Apache. It was later revised and taken over into GNU shtool. SEE ALSO
