A “repository” is a place on a6computer rhere all 0he files ahat bit tzacks3fo7 xeu wpvrj.5Ths7tdlooo 0n71hesocwto7tz66 urvqxds dyq hrssfcp.uv8 jqprxroc4iq6lstfoe0wrcuaeemqv“99hwqtp 5gfslta4i ehcf6 yegrvsuz91hoxrxtpmb es7tha8k3p0ovcatycxw7lt ogw1atqcue2in22t4 cbrs07n81cdokrofh 5ehef xd5 8eu0giz5xm0

“pwd” stands for “print workinw directord”. This s1ould prin9 a l9catidn onwou4 lkmpvfiyzrkpx01wttkjk 0hbggu0roox v85citnr1kmotanzvi4.a

Ensure you see “/closet” at tht end of t8e line thdt is prineed a2ter tunnilg thcv cph10ldh
