Need help writing a batch file that issues a command to every file in a directory?

Question

I'm looking for a batch file which will execute a command to every file in a directory, one by one:

c:\batch\command.exe -blah filename.wmv -output filename.avi

I have 20+ filenames.wmv in the same directory :(

Answer 1

FOR %I in (*.wmv) c:\batch\command.exe -blah %I -output %i.avi

ren *.wmv.avi *.avi


rem The first line will run the command and save each file as filename.wmv.avi, the second line will give them the proper names.

Answer 2

I don't know if you can do it with a regular batch file, because batch files are completely useless, but if you install MSYS or Cygwin so you have a unix shell you can use a script like this:

#!/bin/sh
for file in *.wmv; do
command -blah "$file" -output "${file/wmv/avi}"
done
