You absolutely have to have /bin and /usr/bin on your PATH, _at least_ if you want to be able to run standard UNIX tools. And most likely you'll have a ton of other directories on your PATH as well. I would investigate the shell configuration files etc. and see where you've messed up resetting your PATH variable. > What does "type -a ls" show? > ls is aliased to `ls -F --color=auto --show-control-chars' Yep. There is no ls binary found.
