Search for files in a folder

Question

I'm trying parse a lot of text files using Julia, and I want to loop across an array of file names instead of typing out a function call to read each of them individually. So far I have been unable to find a way to search a folder for files matching a pattern.

Is there a base library Julia function that will return all file names in a given folder, matching a given string pattern?

The equivalent function in R would be list.files(), if that helps communicate what I want.

Answer 1

In Julia, the equivalent to list.files() is readdir([path])

There is no built-in directory search that I know of, but it is a one-liner:

searchdir(path,key) = filter(x->contains(x,key), readdir(path))

---

UPDATE: Since at least Julia v0.7, contains() has been deprecated for occursin(substring, string). So the above filter would now be:

searchdir(path,key) = filter(x->occursin(key,x), readdir(path))
