Walk a directory/Recursively: Difference between revisions

=={{header|Mathematica}}==

The built-in function FileNames does exactly this:

<lang Mathematica>

FileNames[] lists all files in the current working directory.

FileNames[form] lists all files in the current working directory whose names match the string pattern form.

FileNames[{form1,form2,...}] lists all files whose names match any of the form_i.

FileNames[forms,{dir1,dir2,...}] lists files with names matching forms in any of the directories dir_i.

FileNames[forms,dirs,n] includes files that are in subdirectories up to n levels down.

</lang>

Examples (find all files in current directory, find all png files in root directory, find all files on the hard drive):

<lang Mathematica>

FileNames["*"]

FileNames["*.png", $RootDirectory]

FileNames["*", {"*"}, Infinity]

</lang>

the result can be printed with Print /@ FileNames[....]
