I have some custom functions and aliases defined in my .bashrc file. Sometimes I need to execute whem as root. I then do something like:

$ sudo custom_cmd 80                                                                                                                                   
sudo: custom_cmd: command not found

How can I execute such commands with root privileges?

EDIT: Of course to achieve that I could simply source my .bashrc as root but I want to know if there is some quick (in terms of typing needed) way to do this. I also would like to avoid any customization if that is possible (such as sourcing my .bashrc automatically).

Run it through your shell:

sudo bash -c 'source /home/reachus/.bashrc; custom_cmd 80'

Alternatively, write a script which sources .bashrc for you, say /usr/local/bin/my:

#! /bin/bash
source /home/reachus/.bashrc

Then do:

sudo my custom_cmd 80
  • Yes, I can obviously source my .bashrc file but I am looking for more quicker solution. I'll edit my question.

  • @REACHUS write a script which does the same thing: source .bashrc; "$0" "$@".

  • You're right, that should be enough.

  • @REACHUS argh, I mean: simply "$@", since $0 would be the script name.

Just had the same problem.

You can also

  cd /etc/profile.d
  sudo gedit ./newfile.sh (you write commands here, can be nano also)
  sudo chmod +x newfile.sh

It should run automatically whenever you login to your account. To test it, instead of restarting, just run "su yourusername" in bash and login and it should work.
