_N_A_M_E
          alias          Creates a pseudo-command which expands
                         to one or more words, or lists current
                         alias definitions.


SYNTAX
          string alias [_n_a_m_e] [_d_e_f]

          string    _n_a_m_e
          string    _d_e_f


ARGUMENTS
          _n_a_m_e           Provides a name of the alias to define
                         or display. The name must begin with a
                         letter, and can contain letters,
                         underscores, and numbers.


          _d_e_f            Expansion of the alias. That is, the
                         replacement text for the alias name.


DESCRIPTION
          The alias command defines or displays command aliases.
          With no arguments, the alias command displays all
          currently defined aliases and their expansions. With a
          single argument, the alias command displays the
          expansion for the given alias name. With more than one
          argument, an alias is created that is named by the
          first argument and expanding to the remaining
          arguments.

          You cannot create an alias using the name of any
          existing command or procedure. Thus, you cannot use
          alias to redefine existing commands.

          Aliases can refer to other aliases.

          Aliases are only expanded when they are the first word
          in a command.


EXAMPLES
          Although commands can be abbreviated, sometimes there
          is a conflict with another command. The following
          example shows you can use alias to get around the
          conflict.

               prompt> alias q quit

alias           2.  FPGA Express Shell Commands Command Reference


          The following example shows you can also use alias to
          create a shortcut for commonly used command
          invokations.

               prompt> alias include {source -echo -verbose}
               prompt> alias rt100 {report_timing -max_paths 100}

          After the previous commands, the command include
          script.tcl is replaced with source -echo -verbose
          script.tcl before the command is interpretted.


          The following examples show how to display aliases
          using alias. Note when displaying all aliases, they are
          in alphabetical order.

               prompt> alias rt100
               rt100          report_timing -max_paths 100
               prompt> alias
               include        source -echo -verbose
               q         quit
               rt100          report_timing -max_paths 100
