You need to put 'echo' before '$TM_FILEPATH'. So it should be:
    TM_PROJ_FILEPATH=`echo $TM_FILEPATH | sed 
"s|^$TM_SITES_DIRECTORY\(.*\)\$|\1|"`
    echo $TM_PROJ_FILEPATH

Stuff in `...` is executed as a command. $TM_FILEPATH expands to the 
file path, so doing `$TM_FILEPATH` alone would try to execute the file. 
Doing `echo $TM_FILEPATH` instead will echo (print) it. Of course we 
add `echo $TM_FILEPATH | sed ...` to run sed on the result, to replace 
the path prefix. The | char means take output from the command on the 
left side and use as input for the command on the right side.

Not sure how much shell stuff you know!?!

It's a good idea, though personally I'm probably better at answering 
concrete questions than writing general tutorials/documentation.


Kind regards Allan
