Can a grep command be constructed to so it will return all lines with only a specific word or phrase but won't return any lines that contain the same word or phrase when it contains additional words? For example, if a list contains:

Test
TestNumber2
Test Num 3
Test Nbr4 
Test Random text 
Test with more Random Test data.
What if a Test contains this text?

I would like to find a way to return only the lines that contains the single word "Test". In this case, it would return only line 1.

Using anchors, absolutely:

$ grep -e '^Test$' <file>

    Or grep -x Test file
