73. Usage of Alias

1. Alias-define or display aliases

1) alias [alias-name = 'ininal-command']

Alias [alias-name [= string]...]

Alias [alias] = [command name]

Use unalias alias-name to cancel an alias.

2) You can use alias to customize the alias of the command. If you only enter alias, all current alias settings can be listed. The role of Alias is limited to the login operation. If you want to automatically set an alias for each login, you can go to/etc/profile or your own ~ /. Set the alias of the command in bashrc.

Use your favorite text editor to create a file called ~ /. Bash_aliases, and type the alias commands into the file .. bash_aliases will run at login (or you can just execute it with .. bash_aliases ). Bash does not try to recursively expand the replacement text.

3) If you want to add the alias LA = 'LS-al' line to the end of/etc/bashrc, bashrc is the configuration file of environment variables,/etc/bashrc and ~ /. The difference between bashrc is that one is set to the entire system, and the other is set to be used by a single user.
