Unix/ls
< Unix
Unix/ls is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
Write a program that will list everything in the current folder, similar to the Unix utility `ls`.
Example output:
For the list of paths:
/foo/bar /foo/bar/1 /foo/bar/2
When the program is executed in `/foo`, it should print:
bar
and when the program is executed in `/foo/bar`, it should print:
1 2
