The "e" switch extracts files without paths
The "x" switch extracts files with full paths.
Another thing to remember is that the destination dir must end with a colon or slash like this:
lha x file.lha ram:
lha x file.lha ram:stuff/
If you simply want to see what's inside an archive you can use this:
lha v file.lha
You can also re-direct this output to a file like this:
lha v file.lha >ram:archlist
Then you can open ram:archlist in a text editor/viewer.
