我为用户〜/ .bashrc添加了别名，但是“sudo -u user -i'alias_name'”仍然报告“找不到命令”？

Question

As a trivial example, in user foo's ~/.bashrc there is an alias;

alias ll='ls -l'

Using sudo I can see the alias is set;

bar@laptop:~$ sudo -u foo -i alias ll
alias ll=`ls -l'

But, I can't actually use the alias;

 bar@laptop:~$ sudo -u foo -i ll
 -bash: ll: command not found

Commands that are bash functions work, OK. Is there a way to get the aliases to work also?

Answer 1

Try:

alias sudo='sudo '

Answer 2

There is a great example of how to do this in the Archlinux wiki . Add the follwoing to your .bashrc

alias sudo="sudo "

Don't ask me why it works. I've scoured my man pages looking for this without luck, but it's never failed me yet.

Answer 3

make sure you add

alias sudo='sudo '

then go ahead and add your custom alias ... for eg. if regular command is

sudo rm ~/qwerty/removethis.txt

alias for above command will look like

alias your_custom_alias='sudo rm ~/qwerty/removethis.txt'
