How to pass alias through sudo
- by Tanktalus
I have an alias that passes in some parameters to a tool that I use often. Sometimes I run as myself, sometimes under sudo. Unfortunately, of course, sudo doesn't recognise the alias.
Does anyone have a hint on how to pass the alias through?
In this case, I have a bunch of options for perl when I'm debugging:
alias pd='perl -Ilib -I/home/myuser/lib -d'
Sometimes, I have to debug my tools as root, so, instead of running:
pd ./mytool --some params
I need to run it under sudo. I've tried many ways:
sudo eval $(alias pd)\; pd ./mytool --some params
sudo $(alias pd)\; pd ./mytool --some params
sudo bash -c "$(alias pd)\; pd ./mytool --some params"
sudo bash -c "$(alias pd); pd ./mytool --some params"
sudo bash -c eval\ "$(alias pd)\; pd ./mytool --some params"
sudo bash -c eval\ "'$(alias pd)\; pd ./mytool --some params'"
I was hoping for a nice, concise way to ensure that my current pd alias was fully used (in case I need to tweak it later), though some of my attempts weren't concise at all. My last resort is to put it into a shell script and put that somewhere that sudo will be able to find. But aliases are soooo handy sometimes, so it is a last resort.
