You can run multiple commands as a single "block" in Bash using C-style braces. This can be useful for error handling - you can do things like "cd /mydir || { echo "could not cd to /mydir"; exit 1;};" Make sure to remember the semicolon on the last command before the closing brace though, or Bash won't be able to figure out where the block ends.
