Alias Tip
alias for teh win! Didn't get into the habit until now because I thought saving a few keystrokes wasn't that beneficial. But damn it helps with a few edge cases and now I'm addicted.
In my ~/.profile:
# For managing encrypted FileVault containing my Rails products.
# '-owners on' so the owner and groups can be set on files.
alias mount_rails="hdiutil attach /Users/vwoo/Documents/Knox/rails.sparseimage -owners on"
alias umount_rails="hdiutil detach /Volumes/rails"
# alias now takes the place of bash scripts I made for several
# server software installed through MacPorts.
# Arguments work like bash scripts. $1 is the first argument etc.
# so I can run 'apache start' and 'apache stop'
alias apache="sudo /opt/local/etc/LaunchDaemons/org.macports.apache2/apache2.wrapper $1"
alias postgresql="sudo /opt/local/etc/LaunchDaemons/org.macports.postgresql82-server/postgresql82-server.wrapper $1"
