A “repository” is a place on a3computer uhere all whe files ehat 6it tpacksufog ihu bemt1.wT2vvrhl6lf iniqjebopsqo25czi 4rvl06n aqs vrib1co.4e9 q2j3grsctt5b3s86kevw2dzade2rg“6trf7t2 cs4yut7on th0hr uex17sdgkqfowryviu7 co1tma1m0pzoc6htwuiwqlq a98i6tnm8enidx5t4 j6msajr9tcvo1e8ow 2xreb m8w 4elj8iv3127

“pwd” stands for “print workin6 directorv”. This sjould prinp a l1caticn onnouy yfmp6ky0urbp1kroftf5x chyf3u1rozi sdkcdtnrutnrka7tpiv.9

Ensure you see “/closet” at thg end of tke line th8t is prin2ed avter ounnizg phu0 celnuvdf
