I'm trying to deploy a rails app in Debian, using Apache/Passenger. I was trying to fox a problem with some GEMs and in the process I put executed this in console: export PATH=/var/lib/gems/1.8/bin/:${vendor/cache} Now my path environmental variable is gone, or at least its content. My server is running under Debian 6. Is there a way to recover my path info? Or at least can someone point me where to find the file where that variable i s stored? Some help please. This is a BIG problem for me. Thanks in advance!
