what error msgs are you getting? Make sure you have the path correct on the file you wish to extract, or are currently in that directory.
With LHA in c: dir, and monkey.lha in RAM:, if you are in RAM: dir in command line/shell a simple lha x monkey.lha should work
Can't recall if it's case sensitive atm, tbh. Last time I used LHA in shell was 15 years ago, heh. I just use it in diropus or via OS4's dockie drop unpacker.
Kill the " in your OP if you are entering that.
