The Free On-line Dictionary of Computing (30 December 2018):

alias

   1.  A name, usually short and easy to
   remember and type, that is translated into another name or
   string, usually long and difficult to remember or type.  Most
   command interpreters (e.g. Unix's csh) allow the user to
   define aliases for commands, e.g. "alias l ls -al".  These are
   loaded into memory when the interpreter starts and are
   expanded without needing to refer to any file.

   2.  One of several alternative hostnames with
   the same Internet address.  E.g. in the Unix hosts
   database (/etc/hosts or NIS map) the first field on a line
   is the Internet address, the next is the official hostname
   (the "canonical name" or "CNAME"), and any others are
   aliases.

   Hostname aliases often indicate that the host with that alias
   provides a particular network service such as archie,
   finger, FTP, or web.  The assignment of
   services to computers can then be changed simply by moving an
   alias (e.g. www.doc.ic.ac.uk) from one Internet address to
   another, without the clients needing to be aware of the
   change.

   3.  The name used by Apple computer, Inc. for
   symbolic links when they added them to the System 7
   operating system in 1991.

   4.  Two names (identifiers), usually of local
   or global variables, that refer to the same resource
   (memory location) are said to be aliased.  Although names
   introduced in programming languages are typically mapped to
   different memory locations, aliasing can be introduced by
   the use of address arithmetic and pointers or
   language-specific features, like C++ references.

   Statically deciding (e.g. via a program analysis executed by a
   sophisticated compiler) which locations of a program will be
   aliased at run time is an undecidable problem.

Bouvier's Law Dictionary, Revised 6th Ed (1856):

ALIAS, practice. This word is prefixed to the name of a second writ of the
same kind issued in the same cause; as, when a summons has been issued and
it is returned by the sheriff, nil, and another is issued, this is called an
alias summons. The term is used to all kinds of writs, as alias fi. fa.,
alias vend. exp. and the like. Alias dictus, otherwise called; a description
of the defendant by an addition to his real name of that by which he is
bound in the writing; or when a man is indicted and his name is uncertain,
he may be indicted as A B, alias dictus C D. See 4 John. 1118; 1 John. Cas.
