I'm more of a Linux guy :-)

No, not at all. I assume that your PATH is incorrect for the non-'mcidas'
user.
Questions:
- is McIDAS installed as user 'mcidas'
- is the HOME directory for 'mcidas' /home/mcidas
If yest to both, then you should be able to follow the instructions in
the Unidata McIDAS support pages to setup the 'mcidas' and other user
accounts to use McIDAS.

I have attached a script (goescopy.sh) to this email for you to use/modify.
Put this script in a directory in the PATH of the user you want to use
to copy GOES-East/West images and make sure that the file is set to be
executable (chmod +x goescopy.sh).
If you installed McIDAS in the 'mcidas' account, and if /home/mcidas is
the HOME directory for 'mcidas', then 'goescopy.sh' should be ready to
use. I would exercise it using, for example:
cd $MCDATA
goescopy.sh EAST NH 4
^ ^ ^__ image band
| |_____ ADDE dataset descriptor name
|__________ ADDE dataset group name
This invocation will copy the most current GOES-East band 4 (10.7 um thermal
IR) image from the server (goeseast.unidata.ucar.edu) to an element
in the local ADDE dataset MYDATA/IMAGES in position 3004.
Notes:
- the script runs the McIDAS DSSERVE command (dsserve.k) to create an ADDE
dataset of type AREA. The dataset can have all possible AREA files
in it (i.e., files named AREA0001, AREA0002, ..., AREA9999). Because
of the way that MYDATA/IMAGES is (will be) setup, and because of
how I defined things in goescopy.sh, IMGCOPYs will result in:
GOES-East
EAST/<descriptor> BAND=1 - AREA3001 -- 0.65 um visible
BAND=2 - AREA3002 -- 3.9 um short IR
BAND=3 - AREA3003 -- 6.5 um water vapor
BAND=4 - AREA3004 -- 10.7 um thermal IR
BAND=6 - AREA3006 -- 13.3 um co2
GOES-West
WEST/<descriptor> BAND=1 - AREA3011 -- 0.65 um visible
BAND=2 - AREA3012 -- 3.9 um short IR
BAND=3 - AREA3013 -- 6.8 um water vapor
BAND=4 - AREA3014 -- 10.7 um thermal IR
BAND=5 - AREA3015 -- 12.0 um long IR
GOES-10 (GOES-South)
SOUTH/SH BAND=1 - AREA3021 -- 0.65 um visible
BAND=2 - AREA3022 -- 3.9 um short IR
BAND=3 - AREA3023 -- 6.8 um water vapor
BAND=4 - AREA3024 -- 10.7 um thermal IR
BAND=5 - AREA3025 -- 12.0 um long IR
- the location of the files created by the IMGCOPY run from goescopy.sh
will be the $MCDATA directory for the user running the script. This
will be the ~mcidas/workdata directory if the user is 'mcidas', and
the ~/mcidas/data directory if the user is not 'mcidas'.
- since the script will always copy specific bands for specific
satellites to specific output AREA files, it is up to you to add
some intelligence to the script to rename/move the file somewhere
else (otherwise, the next time it is run for the same band for the
same satellite, the previously copied file will be overwritten by
the new one). I can help you out with this task as soon as I
better understand exactly what you want to do.
- the images you copy to your system will be large, so you will
need to have sufficient disk storage to keep a number online
> But it is really a big progress for us to get the GOES data,
> We really appreciate your help.
No worries.
Please test the script to see if you understand what it is doing.
After you "kick the tires", we can talk about what you think is
needed, or to answer any questions you may have (likely since you
have not had any training in McIDAS).
Cheers,
Tom
