For some reason a while back, the behavior of my command line changed, and I don't know why.  Using OSX, now Mountain Lion(although this behavior was present before the switch).Using standard terminal, I would expect back some results from ps, but I get an error:$ ps aux |grep 'asdf'grep: asdf: No such file or directorThis also shows up, for example, here: ln -s /Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl ~/bin/sublln: /Users/peter/bin/subl: No such file or directory
ps aux |grep 'asdf' grep: asdf: No such file or directory
bash;command line;osx
Does it happens when you login as another user?Check output of set ; env; alias. Post it you can't find a problem.
