LINUX: List contents of a outside folder or of a subfolder without leaving current folder

I have a c program that watches over a folder somewhere in your directory (location is given when program starts up). One of its tasks is to tell the user what contents are stored in that specified folder. I was thinking of piping the ls command but I'm unsure how to get contents of a folder in which you are not currently in. Help?

Thanks!

Solution

  • Just use ls?

    ls /path/to/directory

    Alternatively, use opendir() and readdir(), see man 3 opendir and man 3 readdir
