Platform: Ubuntu 10.04 VM running out of VirtualBox

File details:

-rwxr-x---  1 myuser myuser  123 2013-10-31 16:10 myscript.sh

The executable is visible in the directory:

>type myscript.sh
myscript.sh is ./myscript.sh

I do have . in the path:

>echo $PATH
.:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

Running it without sudo works fine:

>myscript.sh

but not with sudo:

>sudo myscript.sh
sudo: myscript.sh: command not found

Why?

    PATH is not inherited in sudo. Doing so would be a security flaw since someone might stick something unsafe in PATH such as ..

Sudo resets PATH, along with many other environment variables, for security reasons. It doesn't matter what is set in /etc/profile, unless you run sudo -i.

The sudo manual page, under SECURITY NOTES, gives an insight about the security implications, along with the options you have to fiddle in your /etc/sudoers file to modify these restrictions, after you understand the implications of doing so."
