String manipulation using ksh
I have a UNIX shell where:
LEVEL=dev
SITE=here
and WHEREIAM=/tmp/$SITE/location/$LEVEL
I want to echo $WHEREIAM in such a way that I get it back with all the environment variables resolved (/tmp/here/location/dev).
This command will be used in a shell script.

NAME
ftpgroups - group password file for use with the SITE GROUP and SITE GPASS commands.
SYNOPSIS
DESCRIPTION
The file is the group password file for use with the SITE GROUP and SITE GPASS commands.
To enable the use of this file, the entry must be made in the configuration file
This file contains an alphanumeric string, encrypted password, and the actual group name from the file. Each entry is separated by After a
user logs in, the SITE GROUP and SITE GPASS commands may be used to specify an enhanced access group and associated password. If the group
name and password are valid, the user becomes (via a member of the group specified in the group access file,
The format of the group access file is:
where access_group_name is an arbitrary (alphanumeric and/or punctuation) string. encrypted_password is the password encrypted via
crypt(3), exactly like in real_group_name is the name of a valid group listed in
NOTE: For this option to work for anonymous FTP users, the ftp server must keep permanently open and the group access file is loaded into
memory. This means that:
(1) the ftp server now has an additional file descriptor open, and
(2) the necessary passwords and access privileges granted to users via SITE GROUP will be static for the duration of an FTP ses-
sion.
If you have an urgent need to change the access groups and/or passwords *NOW*, then kill all of the running FTP servers.
