Since /usr/bin/which is a /bin/bash script, it shares the disadvantage of (H). More so, because now you're running *two* shells whereas a #!/bin/bash script would only need one :) The irony is that the only reason to use which is to accomodate speed freaks who want to be able to use non-bash shells. Now they get hit by the bash startup time anyway. And those same speed freaks are likely to be using ash, which has both "type" and "command -v". I once again recommend a deathmatch between ash and zsh fans. Let the best shell win. Richard Braakman -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
