Windows batch filename globbing

Question

In short, I would like to port this bash expression to a windows batch file:

echo {foo,bar,baz}/*.{agent,event,plan}

Currently I use echo foo/*.agent foo/*.event foo/*.plan bar/*.agent etc... but as the number of directories grow and some new extensions are used it gets very tiresome to modify this line.

Answer 1

One per line (Not sure if that is ok):

@echo off
for %%A in (foo,bar,baz) do (
 for %%B in (agent,event,plan) do echo %%A/*.%%B
)

For all in one line, you probably need a hack:

@echo off
SETLOCAL ENABLEEXTENSIONS
for %%A in (foo,bar,baz) do (
 for %%B in (agent,event,plan) do (SET /P "dummy=%%A/*.%%B ") < NUL
)
echo.

Treat as a list of files and folders (will only print existing files):

@echo off
SETLOCAL ENABLEEXTENSIONS
for %%A in (foo,bar,baz) do (
    for %%B in (agent,event,plan) do (
        for %%C in (%%A/*.%%B) do (SET /P "dummy=%%A/%%~nxC ") < NUL
    )
)
echo.
