- alias - define or display aliases
- alias [ options ] [name[=value]...]
- alias creates or redefines alias definitions or writes the existing alias definitions to standard output. An alias definitions provides
a string value that will replace a command name when the command is read. Alias names can contain any printable character which is not special to
the shell. If an alias value ends in a space or tab, then the word following the command name the alias replaces is also checked to see whether it
is an alias.
- If no names are specified then the names and values of all aliases are written to standard output. Otherwise, for each name that
is specified, and =value is not specified, the current value of the alias corresponding to name is written to standard output.
If =value is specified, the alias name will be created or redefined.
- alias is built-in to the shell as a declaration command so that field splitting and pathname expansion are not performed on the
arguments. Tilde expansion occurs on value. An alias definition only affects scripts read by the current shell environment. It does not
effect scripts run by this shell.
- Causes the output to be in the form of alias commands that can be used as input to the shell to recreate the current aliases.
- Used for tracked aliases. These are aliases that connect a command name to the pathname of the command and are reset when the PATH
variable is unset. The tracked aliases feature is now obsolete.
- Ignored, this option is obsolete.
- Successful completion.
- One or more name operands did not have an alias definition, or an error occurred.
