Is there a way to pipe the "ls" output to a sort by filetype? Cuz I'm recreating teh tree command in a bash script.

Doesn't sort by filetype like the OP is looking for

I have no idea how to sort by file type in bash, however there is a version of tree for linux. Some quick googling even indicates that there are packages for at least a few distros

type in "man ls" or "man ftp" respectively. That will give you all of the options.

Doesn't the -k option of sort allow you to select which characters on a line to sort by? If filetype is in the same position in each line of ls output, it should be trivial.

But what do you mean by position? Sure .* ... wait, would being a directory even show as a filetype?

The number of characters from the start of each ls entry to whatever text indicates file type.

ls | cut -f2 -d.
