Hi I have a directory named Labtest1 and inside that I have 4 subdirectories named group_a, group_b, group_c and roup_d. I have created 4 files namely questions1, questions2, questions3 and questions4. I have also entered some text in these files and saved. Now i have copied the questions1 file to group_a using the command

cp questions1 ../group_a

will the content inside the questions1 file be now available in group_a?
If so how should i view the same? I wanna see if my directory group_a has the questions1 and its contents.
Please help

ls (that is lower case LS) is still the answer. What happens when you try what you propose?

Thanks
