Check matches between two file bash : I've two files like this (but with milion of colums)

**File1.txt**

    some_key1 some_text1
    some_key2 some_text2
    ...
    some_keyn some_textn

**File1.txt**

    some_key11 some_key11 some_text1
    some_key22 some_key22 some_text2
    ...
    some_keynn some_keynn some_textn

In this two files there's some some_text that matches. 

I want to know some_key, some keynn some_keynn and some_text.

Maybe printing the output in one file like ` *somescript* >> result.txt`

Is it possible to do in bash?
