Explanation:-

Code:
eval line=$line      #evaluate the value of line ($line and let line eqal it)
export $line     # export this value to the shell
[[ -n ${line/*_EXE*} ]] || echo $line    # if the $line (may be a file name) that have *_EXE* on its name , if it is null (-n) don't print it , else print it.
||   # let the 2nd command be executed if the first condition is false
