Is anyone aware of a way to find the "ulimit -a" values for another user in Linux? I want user A to be able to check User B's ulimit values. Assumptions are the User A and User B are non-root users.

Thanks in advance

If I am understanding correctly, you are wanting to achieve something like the following...

Assuming I am root and I would like to find out the soft limit information configured for the user fred, the following approach:

su - fred -c "ulimit -Sa"

will return the desired values.

Alternatively, if as per your question, you are not root, then you could use sudo and if desired inject the necessary password on execution as shown here

echo "freds password" | sudo -Siu fred ulimit \-Sa
