1. The basic shell command was broken. Fixed this by replacing

("/bin/ls -d " & quoted form of pwd & query)

with

("/bin/ls " & quoted form of pwd & " | grep -i " & query)

2. if not (exists folder pwdAlias) then gives an error if the insertion location is a file, as happens at least when run from the toolbar in column view. Fixed this by replacing

	set pwdAlias to insertion location as alias
	if not (exists folder pwdAlias) then
		set pwdAlias to (container of pwdAlias) as alias
	end if
	set pwd to POSIX path of pwdAlias

with

	set pwdAlias to insertion location as alias
	try
		if not (exists folder pwdAlias) then
			set pwdAlias to (container of pwdAlias) as alias
		end if
	on error
		set pwdAlias to (container of pwdAlias) as alias
	end try
	set pwd to POSIX path of pwdAlias

which does work, despite being something of a hack.

3. At least after correcting the above two things, the select action was broken, probably because ls didn’t return full paths. Fixed this by inserting

set matchpath to pwd & matchpath

after

repeat with matchpath in paragraphs of matches

Now all is well, at least in my minimal testing. Anyway, here’s hoping formatting doesn’t get messed up, and thanks again for this script.

And yeah, I realize you wrote this years ago.
