Bash

I want to know if it is possible to modify my bash to intercept dangerous command like rm -rf / test/ble/... (notice the space) and to allow my user to see only process they own.

I think you can create an alias for "rm" that acts as a safety net. I'm not a Bash expert, but I know theres a Bash scripting guide at the Linux Documentation Project http://www.tldp.org

()bash to intercept dangerous command like rm -rf / test/ble/... (notice the space)
usually in ~/.bashrc: "alias rm='rm -i'"
Note this only is effective for root, as regular users don't have permission to delete "/" (not talking about symlinking and tricking some app with $UID=0 into deleting).

and to allow my user to see only process they own.
look at the GRSecurity patch kernelpatch.
