How do I sudo if in Bash?

bash, shell, sudo

Solution

You need to run it under a subshell. Example:

if sudo bash -c '[[ -d "/home/otheruser/svn" ]]'
then
  echo "SVN exists"
else
  echo "SVN does not exist"
fi

Problem

I need to check for a directory in the home directory of another user. Normally I would sudo but that forks another process and I also lose my environment. For example, I have: ``` if [[ -d "/home/otheruser/svn" ]]; then echo "SVN exists" else echo "SVN does not exist" fi ``` I need the the test condition to run with root permissions.
