Create an alias

See also : alias

Use command alias Create an alias for an executable command on a specific instance . The following code uses this command to create an alias lscc, This alias will appear in the instance crazy-cat Middle execution command ls:

$ multipass alias crazy-cat:ls lscc

After executing this command , Alias lscc Will be defined in the instance crazy-cat On , And bind the execution command ls. If lscc Be deleted , The alias of the command is the default command ( This situation is ls).

Translation notes : I understand the meaning of this sentence is : lscc After the alias is deleted , ls The default alias for is ls, That is, you are your own command alias

Enumerate defined aliases

See also : aliases

Look at the list of aliases defined so far , Use aliases command :

$ multipass aliases
Alias Instance  Command
lscc  crazy-cat ls

Execute alias

There are two ways to execute aliases .

multipass <alias>

The first way to execute an alias is

$ multipass lscc

This will enter crazy-cat Example of shell, And implement ls, Then return to the host command line , Be similar to exec command

Parameters are also supported , use -- separation :

$ multipass lscc -- -l

<alias>

The second way to perform aliasing is a two-step process :

add to Multipass Alias script folder to system path

First , Add alias script folder to system path . The first time you create an alias , The guidance will be displayed automatically , Each platform displays differently . for example :

$ multipass alias crazy-cat:ls lscc
You'll need to add this to your shell configuration(.bashrc, .zshrc or so) for alias to work withour prefixing with `multipass`

PATH="$PATH:/home/user/snap/multipass/common/bin"

Linux

Linux Upper shell The configuration needs to be modified . In most Linux In the version , default shell yes bash, It can be in the user's home Directory through file .bashrc To configure . Any text editor can modify the file , for example :

$ nano ~/.bashrc

When editing a file , Add a new line at the end of the text as follows :

export PATH="$PATH:/home/user/snap/multipass/common/bin"

( Remember to change the folder to the correct folder in the above case command , And restart shell)/

In the use of zsh As shell In the scene , The files to be modified are .zshrc instead of .bashrc; The steps are the same .

macOS

stay MacOS On , Most commonly used shell yes zsh. Steps and... To add a folder to the system path Linux It's the same , As mentioned above

Windows

However , stay Windows On , A little complicated . To make the changes permanent , Need to use PowerShell Store old system paths , Add alias folder , And store the new path of the trace .

$old_path = (Get - ItemProperty - Path 'Registry::HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Environment' -Name PATH).path
$new_path = "$old_path;C:\Users\<user>\AppData\Local\Multipass\bin"
Set-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Environment' -Name PATH -Value $new_path

Don't forget to restart the terminal . The folder has now been permanently added to your path , Multipass You can now reference aliases to perform .

Execute alias

Once you add the alias folder to the system path , You can just （ No need to write multipass） The implementation is as follows ：

$ lsccat alias definition time,

This command （ Path based has been added to the system path ） Equivalent to multipass lscc. And support parameters , And there's no need to --:

$lscc -l

Remove alias

See also ：unalias

Last , Remove alias lscc, Issue commands ：

multipass unalias lscc

️ When the instance is cleared （purged） When , Aliases will also be removed . That means ,multipass delete crazy-cat --purge The alias will also be removed lscc.
