  • Bash - Can I create cascading aliases, that is an alias of an alias?

    From Ottavio Caruso@21:1/5 to All on Fri Apr 29 15:44:32 2022
    Hi,

    Assuming:

    alias yt='/home/user/bin/yt-dlp'

    and I want have more aliases incorporating this alias:

    alias yt-native='yt --hls-prefer-native"
    alias alias yt-auth='yt -u user@email.com -p password"

    so that I don't have to repeat the location of yt-dlp.

    Is that possible?

    So why don't you just try it?

    You type this _once_ into your .bash_aliases!
    You could even repeat lines. Too much trouble?
    Or are you just trolling?

    Yes. I'd say that method sucks, however. Personally I use a wrapper
    script for yt-dlp that sets my preferred options and gives me handy
    command line shortcuts.

    But you can do some fun stuff with aliases.

    When an alias definition ends with a space, the following term can also
    be an alias. The typical use-case is an alias with nice, time, sudo or
    the like that you would prefix to a regular comandline.
    It can also be used to rename options.

    alias yt='/home/user/bin/yt-dlp '
    alias _native='--hls-prefer-native '
    alias _auth='-u user@email.com -p password '
    alias e='echo '

    Now you can chain them, and order doesn't matter.

    $ e yt _native _auth
    /home/user/bin/yt-dlp --hls-prefer-native -u user@email.com -p password
    $ e yt _auth _native
    /home/user/bin/yt-dlp -u user@email.com -p password --hls-prefer-native
    $

    But seriously, write a wrapper script.

    Or just use shell functions to avoid the restrictions of aliases and
    get the advantages of both.

    Ah, thanks. That's the one I was looking for. It's buried somewhere in
    the man page (hints are welcome) but I can't find it. However...

    But seriously, write a wrapper script.

    I agree.

    If the last character of the alias value is a blank, then the next command
