Unix Chattr Remove Immutable Flag Home Shell Rc

Execution of chattr -i against shell initialization files within $HOME (e.g., $HOME/.bashrc, $HOME/.zshrc) to remove the immutable attribute. The command suppresses errors (2>/dev/null) and forces a successful exit (|| true), indicating a deliberate attempt to silently restore write access to user-level shell configuration files in the current user’s home directory.
