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).
