eshell: Aliases

 
 2.5 Aliases
 ===========
 
 Aliases are commands that expand to a longer input line.  For example,
 ‘ll’ is a common alias for ‘ls -l’, and would be defined with the
 command invocation ‘alias ll ls -l’; with this defined, running ‘ll foo’
 in Eshell will actually run ‘ls -l foo’.  Aliases defined (or deleted)
 by the ‘alias’ command are automatically written to the file named by
 ‘eshell-aliases-file’, which you can also edit directly (although you
 will have to manually reload it).
