Syntax
- 
alias [-gp] [name[=value]…]
Description
The alias built-in defines and/or prints aliases as specified by operands. The printed aliases can be used as (part of) shell commands. The built-in prints all currently defined aliases when given no operands.
Options
- 
-g
- 
--global
- 
With this option, aliases are defined as global aliases; without this option, as normal aliases. 
- 
-p
- 
--prefix
- 
With this option, aliases are printed in a full command form like alias -g foo='bar'. Without this option, only command operands are printed likefoo='bar'.
Operands
- name

The name of an alias that should be printed. 
- name=value

The name and value of an alias that is being defined. 
Exit status
The exit status of the alias built-in is zero unless there is any error.
Notes
The characters that cannot be used in an alias name are the space, tab,
newline, and any of =$<>\'"`;&|()#.
You can use any characters in an alias value.
The alias built-in is a semi-special built-in.
The POSIX standard defines no options for the alias built-in, thus no options are available in the POSIXly correct mode.
