Applescript loop through result of “ls” with “do shell script”

Question

I have selected a list of files in Applescript using:

set variableName to do shell script "cd /; cd dev/; ls tty.usb*"

When I print out variableName, it shows this list:

file1
file2

From here, I want to loop through each of them using:

repeat with theItem in variableName
   display dialog theItem
end repeat

Instead of showing "file1" and "file2" one by one, it shows "f, i, l, e, 1," and so forth.

How can I loop the list to get a complete file name?

Answer 1

Thanks for the helpful responses! I have found out the solution.

set variableName to do shell script "find /dev/tty.usb*"
display dialog variableName

set testArray to paragraphs of the variableName

repeat with theItem in testArray
   display dialog theItem
end repeat

By using paragraphs, I'm able to split by newline and covert the result into a list.
