diff between sudo and su

[gany59]

what is the difference between the sudo and su

[Patrick Wallek · Accepted solution]

su requires that you know the password of the user you are su'ing to, if you are not root.

sudo lets you set users up to do things so that they do not need to know the root password.

sudo will also create a log entry including what command was executed.

su will only log the su attempt in /var/adm/sulog

For Sudo:

Please follow the links above and read the manpages, they should really help. But basically sudo can provide more granular control on permissions than su.
