Change user in script

i have a script that needs to be run as a specific user. lets call this specific user "skysmart".

sure, i can check the username of the person running the script and if it isn't "skysmart", simply abort with a descriptive error message. but then, that would require the user to have to "sudo su -" to skysmart and then rerun the script. i'd like to avoid this.

so, if this script is run as root, i want it to automatically "sudo su -" to "skysmart", and then run. without any further intervention from the user.

sample code:
Code:
if [ "${LOGNAME}" = "root" ] ; then

su - skysmart

........

NAME
script - Makes a transcript of terminal session SYNOPSIS
script [-a] [file] The script command makes a transcript of everything printed on your terminal. OPTIONS
Appends the transcript to file rather than writing it to file. OPERANDS
The name of an output file that will contain the transcript of the session. If this parameter is omitted, the file typescript is written. DESCRIPTION
The transcript is written to file, or appended to file if the -a option is given. If no file name is given, the transcript is saved in the file typescript. The script ends when the forked shell exits. This program is useful when you are using a CRT and want a hard-copy record of the dialog (for example, a technical writer might create an example of a working session this way). If you specify the -a option and the file does not exist, it is created. If you do not specify the -a option and the file exists, it is replaced. RESTRICTIONS
The script command requires a streams based terminal. In single user mode, streams may not be enabled. Under these circumstances, script will exit with no action. If you are the superuser and need to run this command in single user mode, use the following special instruc- tions. Enabling Streams If it is necessary to enable a streams environment in the single user mode, enter the command /sbin/init.d/streams. This command is avail- able to the superuser only. SEE ALSO
Commands: autopush(8), cat(1), echo(1), strsetup(8), tee(1) System Administration script(1)
