## existence of the specified inode by any testable type. If two arguments

## are passed assumes the first is a valid argument to the test command

## (man test for details). If just one assumes a type of -e if the name

## matches the base name of the command (default: pdhas). Otherwise, the

## last character of the file name is assumed to be the type (without the
